21:09:56 [Step_1] which tract is for voluntary refined movements of the distal extremities?

21:10:59 Lorena enters this room

21:11:13 [Step_1] hi lorena.....great to see you

21:11:28 [Lorena]

21:11:32 [Lorena] hi everybody

21:11:44 [hutals] hi lorena

21:11:45 [butter] hi

21:12:17 [Lorena] just came to say hi and will join you for sure next one, i miss you guys!!

21:12:18 [Step_1] for those who dont know, lorena is one of the people who helped get these chats started

21:12:32 [Step_1] we miss you too lorena

21:13:14 [Lorena] i am so happy the chats continue so i dont distract you more , see you soon

21:13:38 [Lorena] study and enjoy your studies, best of luck again in your score step 1!!

21:13:42 [Step_1] thanks for stopping by. see ya in the next chat

21:13:50 [Step_1] thanks!

21:14:01 [Lorena] nice to see you again hutals, bye

21:14:06 [hutals] bye lorena

21:14:32 [hutals] i think the answer is corticospinal tract. is that right?

21:15:01 [Step_1] lorena is great. you guys will gain alot from her participation

21:15:27 [Step_1] yes hutals, the answer is corticospinal tract...good job

21:16:03 [Step_1] what is the difference between UMN and LMN signs?

21:17:34 [butter]>[Step_1] flaccid muscle in LMN, Barbinski and hyperreflex in UMN,

21:18:02 [Step_1] UMN has everything increased and LMN has them decreased.....so UMN has spastic paralysis, hyperreflexia, pos babinski, inc muscle tone, etc while LMN has flaccid paralysis, areflexia, no babinski, etc....good job butter

21:18:10 [ayouh] in umn everything is up, spastic paralysis, Hyperreflexia, +ve babinski, large area involved, and increased muscle tone....where everything is down is lmn

21:18:42 [ayouh] same way i memorized it step 1...cooll...

21:18:44 [Step_1] yes, very good ayouh

21:18:56 [butter] muscle fasciculation appear in UMN or LMN?

21:19:03 [freaha] hi every one

21:19:13 [butter] hi freaha

21:19:17 [Step_1] hi freaha

21:19:20 [freaha] in LMN

21:19:26 [hutals] hi freaha

21:20:26 [Step_1] LMN

21:20:42 [Step_1] sorry, didnt see the question until now

21:21:12 [freaha] well ...in a lesion of bulbospinal tract which cranial nerves show problems???????

21:21:51 [butter] facial nerve VII

21:22:08 [freaha] and

21:22:40 [Step_1] 8?

21:22:49 [butter] i thought all others get bilateral control except contralateral lower face

21:23:04 [butter] yeh decreased sound localization

21:23:33 [freaha] facial and hypoglossal nerve

21:24:16 [Step_1] good one

21:24:27 [butter] why XII?

21:25:45 [Step_1] question described a pt who stubbles in the dark, but is fine in daylight. what do you think it might be?

21:26:16 [butter] vestibulo prob?

21:26:58 [Step_1] hint.....when eyes closed and fall over, this is pos rhombergs, so dorsal column. when eyes open and fall over, this is cerebellar

21:26:58 [freaha] nightblindness

21:27:27 [freaha] ohh

21:27:47 [butter] i c

21:28:51 [hutals] thats a good point

21:29:29 [butter] where is the cell bodies of corticospinal tract?

21:30:01 [Step_1] sorry, my computer is slow.....since it is dark, it is the same as if the eyes are closed, so the person has sensory problems which means a problem with dorsal column, medial leminiscus pathway

21:30:35 [butter] yeh i c, the dark room suggest can't use eyes to adjust

21:31:08 [butter] i was thinking this way but confused DC with vestibulo prob, always confuse things

21:31:37 [butter] Where are the cell bodies of spinothalamic tract?

21:31:45 [Step_1] thats ok, better now than in the test

21:32:04 [butter]>[Step_1] yeh sure

21:32:28 [Step_1] VPL

21:32:43 [freaha] butter why dont u tell us about all the cell bodies....the ones u have asked and the ones u r abt to ask....cuz i really dont know

21:33:11 [butter] I just saw these two in my notes right now

21:33:28 [freaha] hmm

21:33:39 [butter] cell body of dorsal column should be in dorsal root ganglia

21:34:04 [butter] cell body of spinalthalamic tract should be in dorsal horn

21:34:42 [butter] cell body of corticospinal tract should be in motor cortex (precentral gyrus?)

21:34:42 [Step_1] thanks

21:35:07 [butter] make sure you can identify the structure when asked about cell bodies, that's what i heard in the lecture

21:36:00 [Step_1] what disease will effect both upper and lower motor neurons?

21:36:46 [butter] amyotrophic lateral sclerosis

21:36:57 [freaha] ALS

21:37:18 [Step_1] ALS (Lou Gerigs Dz) will effect both UPN and LMN....good job butter and freaha

21:38:48 [butter] if barbinski sign is positive on the right, where is the lesion of UMN, left or right?

21:39:40 [Step_1] UMN on the left

21:39:58 [freaha] butter the both sensory tracts have there cell bodies in dorsal root ganglia....check it out

21:40:43 [Step_1] well depends....contralateral if in brainstem or above, but can be ipsi if it is in the spinal cord

21:40:50 [freaha] UMN lesion can be on left if above the

21:40:53 [freaha] rite

21:41:28 [butter]>[Step_1] yeh, can't tell depending on above or below pyramidal decussation

21:42:07 [freaha] wht does syringomylia cause....

21:42:07 [Step_1] almost had me....had to think that one through a bit

21:42:36 [Step_1] bilateral loss of pain and temp at the level of the lesion

21:43:45 [butter] they point to spinothalamic tract, at that point assume lesion of tract is below cervical spine, the cell body of this tract should be the second neuron, which is dorsal horn

21:44:26 ash enters this room

21:44:39 [Step_1] hi ash

21:44:45 [freaha] yeah rite step 1....cuz it causes a central cavitation...and destroy the crossing over spinothalamic tracts

21:44:48 [ash] hi everyone

21:44:49 [hutals] hi ask

21:45:07 [butter] hi ash

21:45:21 [ash] hi all

21:45:24 [Step_1] infection in caverous sinus gives symptoms of diplopia, eyes pointed nasally, medially strabismus....which CN is effected?

21:45:43 [butter] abducens VI?

21:45:48 [ash] abducent

21:45:57 [freaha] hi ash

21:46:07 [ash] hi

21:46:23 [Step_1] yes, these are signs of deficit in abducens or CN 6, which goes through the cavaernous sinus

21:47:01 [ash] lesion at the base of pons can give what syndrome?

21:47:03 [butter] horner syndrome is always ipsilateral, true or false?

21:47:38 [ash] where corticobulbar and corticospinal tracts are affected

21:47:51 [freaha] true

21:47:58 [Step_1] true?

21:48:39 [ash] insyringomtlia

21:48:46 [ash] of cervical cord

21:48:57 [ash] syringomylia

21:49:49 [ash] alcohol abuse can affect what part of cervix?

21:49:50 [freaha] weber???

21:49:57 [ash] yes/TO butter

21:50:58 [butter] pontine lesion has medial vs lateral right?

21:51:07 [ash] sorry i meant alcohol abuse can affect what part of cerebellum

21:51:19 [butter] vermis

21:51:26 [freaha] yeah rite

21:51:32 [Step_1]>[ash] ahh, that changes things

21:51:38 [butter] therefore proximal (trunk) is affected, can't keep balance

21:52:12 [Step_1] i agree

21:52:22 [ash] sorry

21:52:38 [Step_1] anterior vermis to be exact

21:53:16 [butter] cerebellar and its peduncle lesion always ipsilateral by the way

21:53:18 [Step_1] no prob....i was scratching my head on that one...lol

21:53:33 [ash] paralysis of upward and downward gaze and noncommunicating hydrocephalus.what syndrome>?

21:53:37 [freaha] ant vermis

21:54:19 [freaha] it starts with a P

21:54:31 [freaha] .........

21:54:37 [ash] next is a

21:54:58 [ash] parinauds syndrome

21:55:02 [freaha] parinauds

21:55:14 [ash] or dorsal midbrain s.

21:56:27 [hutals] contralat spastic hemiparesis of body, contralat loss of position and vibration sense on body, tongue deviates to lesion side....what syndrom?

21:56:56 [ash] medial medullaryi

21:57:56 [Step_1] medial med....i agree

21:57:57 [freaha] did anyone read about paramedian midbrain syndrome??

21:58:17 [ash] yes

21:58:19 [hutals] yes, thats right

21:58:33 [ash] it is called benedicts syndrome

21:59:15 [ash] occulomotor n.,dentatothalamic tract and medial lemniscus affected

22:00:19 [freaha] in benedicts ....the dentothalamic fiber lesion causes contralaterl cerebellar dystaxia....does it make sense...???? CONTRALAT. cerebellar

22:00:37 [ash] trigeminal tracts go to which thalamic nucleus?

22:01:32 [butter] do you use kap-lan notes? can't find benedict, remember seeing it

22:01:51 [ash] dentate nucleus projects to contralateral thalamus so it makes sense

22:02:02 [butter] double cross

22:02:11 [butter] equals ipsilateral

22:02:38 [butter] benedicts is also red nucleus syndrome?

22:02:48 [butter] i mean red nucleus lesion

22:03:52 [butter] basal ganglia lesion is to contralateral side

22:04:16 [butter] just so that you know

22:04:51 [hutals] ipsilat limb ataxia, ipsi pain and temp loss in face, contra pain and temp body, vomiting, vertigo, nystagmus away from lesion, horners syndrome, ipsilat paralysus of vocal cord, dysphagia, palate droop. what syndrome?

22:04:58 [ash] trigeminal tract goes to which thalamic nucleus?

22:05:31 [butter] VPN?

22:06:23 [hutals] oops, wasnt supposed to hit sent yet

22:06:58 [butter] medial

22:07:10 [ash] good

22:07:20 [ash] what goes to lateral?

22:07:21 [Step_1] VPM

22:07:34 [butter] pain and tem from face medial, p&t body lateral right?

22:07:55 [ash] right

22:07:58 [freaha] thanks guy si figured it out

22:09:09 [butter] uncus herniation will cause what cranial nerve palsy?

22:09:32 [freaha] last 4

22:09:51 [ash] ipsilateral facial paralysis and medial strabismus what is the site of the lesion?

22:09:55 [Step_1] to help with the vascular lesion syndrome, easiest thing is to figure out from the CN deficit. this will tell you a couple of things. first, which side lesion is on because CN lesions always ipsilat. also will give you idea of level depending on where CN is located

22:10:41 [Step_1] from there, you can match the rest of the symptoms to confirm

22:11:44 [freaha] hutals whts the syndrome

22:12:04 [ash] presbiacusis affects what frequencies of sound?

22:12:25 [hutals] lateral medullary syndrome (aka wallengergs syndrome)

22:13:36 [Step_1]>[ash] i'd like to say medial pons, but sounds more like lat pons??

22:14:41 [ash]>[Step_1] it is pons but i want the specific site

22:15:04 [butter] what's the afferent and efferent nerve for blink reflex?

22:15:53 [ash] congenital facial diplegia +convergent squint what syndrome?

22:16:56 [butter] yeh i think so

22:17:05 [ash] if then ophthalmic nerve and facial nerve

22:17:09 [freaha] ash is it ...the facial colliculus

22:17:31 [hutals] is it 7 and 9?

22:18:07 [hutals] or 5 and 7 i think

22:18:29 [freaha] 5 and 7

22:18:32 [ash] congenital facial diplegia +convergent squint ,what syndrome?

22:18:50 [butter] what are the nerves that 1. open the eyes 2. close the eyes 3. keep the eyes open?

22:19:28 [freaha] 7 3 7

22:19:36 [freaha] no 3 7 3

22:20:05 [freaha] ash the low frequencies

22:20:18 [ash] yes

22:20:45 [freaha] and tell the difficult syndrome

22:21:14 [freaha] ok

22:21:17 [ash] the syndrome is mobius syndrome

22:21:51 [butter] think it's not on kap-lan notes

22:22:00 [butter] anyway, will check this out later...

22:22:07 [hutals] i couldnt find it in kap lan either??

22:22:36 [ash] i read h i g h y i e l d

22:22:36 [hutals] where did you get that one from ask?

22:23:11 [ash] it is supposed to be good for anatomy as comparwed to k a p l a n

22:23:15 [hutals] you mean from goljans high yield, or do you mean high yield neuro or anatomy?

22:23:39 [ash] h.h.neuro

22:23:48 [ash] h.y.neuro

22:24:22 [freaha] HY is good...i did a bit of it

22:24:28 [hutals] thanks ash

22:24:39 [Step_1] placidity, excessive excitatory, hypersexuality, hypersatiety, inability to learn, visual and tactile agnosia. what syndrome?

22:24:48 [ash] what lesion of hypothalamus results in poikilothermia?

22:25:28 [ash]>[Step_1] kluver busy s.

22:25:49 [freaha] butter ..so affrent is 3 and effrents r 7 and sym

22:25:57 [hutals] kluver bucy

22:27:33 [ash] ipsilateral anosmia,optic atrophy and contralateral papilloedema.syndrome?

22:27:44 [hutals] posterior nucleus

22:28:18 [Step_1] this is kluver bucy syndrome (ant temporal lobe containing hippocampus and amygdala)....good job ash and hutals

22:28:50 [ash] hippocampus is the most epileptogenic part of cerebrum.why?

22:28:54 [Step_1] agree with hutals, lesion in post nucleus of hypothal results in poikilothermia

22:30:05 [ash] but why do we see that part affected in the first place??

22:30:43 [ash] no

22:31:48 [Step_1] no to what? its not in the post nucleus?

22:32:01 [ash] ans is the sommers secter in hippocampus is very sensitive to ischemia and therefore epilepsy in this region

22:32:03 [butter] this area is activated constantly, like some routine events?

22:32:14 [ash] no to butters ans

22:32:43 [butter] so it's becoz more prone to ischemic attack?

22:32:46 [butter] i c

22:32:51 [ash] yes

22:33:37 [Step_1] hhhmmm, i didnt even see butters answer. i'm getting a weird connection today

22:33:39 [ash] ipsilateral anosmia,optic atrophy and contralateral papilloedema.syndrome?

22:34:36 [butter] temporal lobe prob?

22:34:36 [Step_1] kennedy syndrome?

22:34:54 [freaha] [ash] what lesion of hypothalamus results in poikilothermia?,,,,asnwer........

22:35:08 [ash] high dose thiamine therapy,spinal ataxia,optic atrophy and nerve deafness.what syndrome?

22:35:46 [ash]>[Step_1] yes foster kennedy syndrome

22:35:56 [ash]>[Step_1] good

22:37:17 [Step_1] Strachan's syndrome

22:37:23 [ash] wilsons disease affects which nucleus of cns?

22:37:35 [ash]>[Step_1] i am impressed

22:38:25 [hutals] none of this stuff is in kap lan, so now i feel stupid. do we need to study stuff on top of everything in kap for neuro, or is kap enuf?

22:39:31 [freaha] wilson effect basal ganglia

22:39:33 [butter] i watched kap-lan new videos in anatomy and neuro, a lot more shorter than old one

22:39:49 [freaha] I GUESS &lt;a target=new href=http://click.linksynergy.com/fs-bin/click?id=c97WUMRO5hY&offerid=47491.10002441&type=3 &subid=0 >Kaplan&lt;/a><IMG border=0 width=1 height=1 src=http://ad.linksynergy.com/fs-bin/show?id=c97WUMRO5hY&bids=47491.10002441&type=3&sub id=0 > IS NOT ENUF

22:39:57 [ash] i suggest h i g h y i e l d series for anatomy

22:40:47 [freaha] i used ridiculously simple and bit of HY bit of &lt;a target=new href=http://click.linksynergy.com/fs-bin/click?id=c97WUMRO5hY&offerid=47491.10002441&type=3 &subid=0 >Kaplan&lt;/a><IMG border=0 width=1 height=1 src=http://ad.linksynergy.com/fs-bin/show?id=c97WUMRO5hY&bids=47491.10002441&type=3&sub id=0 >

22:41:03 [hutals] i thought i knew alot by learning kap lan neuro past few days, but i havent seen alot of the questions ash is asking

22:41:18 [butter] i feel same

22:41:38 [freaha] me too feel bad

22:41:46 [Step_1] freaha, you cant type words like kap lan, amaxon, first aid, etc or you will get that link

22:41:55 [butter] in the new video they stress that only 3 long tracts are required to know, as to current trend, then brain stem lesion important too

22:42:15 [freaha] ok ash tell all the answers....

22:42:30 [freaha] ok i get it

22:42:30 [ash] come on guys you are doing well

22:42:53 [ash] please dont feel bad .that was not my intention

22:43:14 [hutals] i agree, kap is not as in depth because it covers only the really high yield stuff.

22:43:30 [freaha] no its good tht we know wht to do....need to study more of neuro

22:43:50 [ash]

22:43:54 [hutals] we know ash that you did not have bad intentions. i think we just studied different sources so hard to answer your questions.

22:44:20 [butter] after all we are taking same exam

22:44:41 [freaha] [ash] wilsons disease affects which nucleus of cns?

22:44:48 [hutals] just hope you dont think we didnt put in the effort to study for the session or something because i put alot into it, but its not showing

22:45:06 [freaha] guys dont get down......lets studyyyyyy and learn more and more

22:45:33 [hutals] i agree, i'm learning alot from ash and the rest of you....lets move on

22:45:38 [freaha] so shalll we .........

22:45:56 [Step_1] ok, where were we?

22:47:04 [ash] pt.has topographic memory loss,anosognosia,construction apraxia,dressing apraxia,what part of the brain is affected?

22:47:19 [freaha] basal ganglia....

22:47:43 [freaha] i dont know abt caudate

22:48:38 [freaha] [ash] high dose thiamine therapy,spinal ataxia,optic atrophy and nerve deafness.what syndrome..answer plz

22:49:05 [hutals] middle cerebral artery stroke?

22:49:36 [freaha] Strachan's syndrome.....wht is this syndrome

22:49:50 [freaha] ok

22:51:28 [hutals] basal ganglia, and the posterior and anterior internal capsule?

22:52:10 [butter] what's the wilson answer, ash?

22:53:04 [ash] now you guys ask some questions

22:53:14 Pascal enters this room

22:53:25 [freaha] IT IS THE INFERIOR PARIETAL LOBE OF NON DOMINANT HEMISPHERE

22:53:35 [hutals] your asking some good questions ash, please continue

22:53:48 [Step_1] hi pascal

22:53:48 [freaha]

22:54:03 [freaha] HI PAS

22:54:11 [ash] what test is used to test cerebral dominance?

22:54:19 [ash] hi pascal

22:54:35 crusher enters this room

22:54:53 [crusher] hi everyone

22:54:58 [freaha] SHOW ME WHICH HAND U WRITE WITH...ASH SO I CAN TEST U

22:55:11 [freaha] AM I RITE

22:55:18 [Step_1] what is the blood supply to the anterior limb of the internal capsule? question actually had a pic of the three limbs and pointed to an infarction and asked which vessel caused this

22:55:29 [Step_1] hi crusher

22:55:34 [freaha] HI CRUSHER

22:56:02 [ash] hi crusher

22:56:13 [butter] hi crusher

22:56:30 [freaha] HOW DO U CHECK FOR CEREBRAL DOMINENCE

22:57:12 [butter]>[Step_1] ante limb ACA, rest of it MCA

22:58:17 [Step_1] excellent butter!

22:58:53 [butter]>[Step_1] yeh.....just looked and copied

22:59:29 [ash]>[Step_1] antwerior choroidal artery?

22:59:41 [butter] hypertensive pt wake up in the morning and hd pure motor defect, what's wrong?

23:00:27 [crusher] stroke

23:00:50 [butter] sorry, i mean what part of brain is affected?

23:00:54 [ash] patienthas right and left confusion,finger agnosia,dyslexia,dyscalculia,contralat.hemianopia. what syndrome?site?

23:01:23 [Step_1] corticospinal tract i guess with info given

23:02:18 [crusher] parital lobe ..motor area.

23:03:18 [butter] lateral striate branches of MCOA supply posterior limb

23:04:01 [ash]>[Step_1] is ant.choroidal artery right for ant.limb?

23:04:20 [butter] MCA, not MCOA

23:04:58 [butter] actually post limb that close to genu

23:05:49 [ash] guys what about my syndrome?some ans?

23:07:16 [ash] gerstmanns syndrome involves inferior perietal lobule of dominant hemisphere

23:07:44 [butter] hmm i should know this one

23:07:46 [Step_1]>[ash] it was the ant cerebral artery as the main blood supply. not sure about branches.

23:08:04 [freaha] IN HYPERTENSION...THERE CLD B THROMBOEMBOLISM..OR INTRACEREBRAL BLEED...

23:09:03 [ash]>[Step_1] yes the branches are medial striate which supply the ant.limb

23:09:30 [Step_1]>[ash] thanks

23:09:55 [Step_1] maybe we should do some histo since our time is running out. what do you think?

23:10:03 [butter] ok

23:10:26 [butter] in cardiac muscle, what binds to calcium?

23:11:36 [hutals] troponin?

23:12:22 [freaha] Step_1] what is the blood supply to the anterior limb of the internal capsule? question actually had a pic of the three limbs and pointed to an infarction and asked which vessel caused this...ANSWER PLZ

23:13:33 [ash] ant.cerebral a.(medial striate branches) for ant. limb

23:13:42 [freaha] TROPONIN

23:14:19 [ash] middle cerebral a.(lat.striate branches)for posterior limb

23:14:26 [Step_1] the choices gave anterial cerebral , middle cerebral, post cerebral, and a couple of others. the answer was ant cerebral, but ask pointed out that the branches are the medial striate.

23:15:03 [ash] also ant.choroidal a. which is a branch of internal carotid a. for post.limb

23:15:27 [Step_1] i agree that ca binds to troponin

23:15:45 [butter]>[Step_1] troponin C

23:15:50 [butter] remember this point
