8:50 PM [roxanita]
8:50 PM [mmw] para erectoin and symp ejection
8:50 PM [ttw] sym
8:50 PM [roxanita] Para--erection, Eyac---sympat
8:50 PM [usmle_guy] Points and Shoots, so Parasympathetic is erection (Point) and Sympathetic is ejaculation (Shoots)
8:51 PM [mmw] if AFP dec ---Down ,If AFP inc anencephaly
8:51 PM [clover] nice way to remember
8:51 PM [roxanita] wow usmle_guy, that's agood one

8:58 PM [usmle_guy] anacephaly
8:58 PM [roxanita] yes!
8:58 PM [usmle_guy] caudal would be spina bifida
8:58 PM [mmw] meninges +s.c project through vertebral degect and inc AFP?
8:59 PM [roxanita] Failure to close anterior Neuropore results in Anencephaly and Failure to close POSTERIOR NEUROPORE results in SpINA BIFIDA
8:59 PM [roxanita] relate anterior with head and posterior with the spine
8:59 PM [usmle_guy] meningomyelocele
8:59 PM [mmw] i did'nt know this
9:00 PM [mmw] thanks rox
9:00 PM [mmw] myeloschisis?
9:01 PM [mmw] *choochoo*
9:01 PM [roxanita] Meningomyelocele is when meninges and spinal cord are projected
9:01 PM [roxanita] good wake up
9:01 PM [mmw]
9:02 PM [usmle_guy] mmw, your question said the meninges + spinal cord, so that would be meningomyelocele. if an open cord, then myeloschisis....right?
9:02 PM [roxanita] Myeloschisis is an open neural tube , is very severe form
9:02 PM [mmw] yes rox
9:02 PM [mmw] whar r glial cells?
9:02 PM [mmw] wake up guys
9:03 PM [roxanita] all cases of Spina Bifida except for the S.B Occulta have high AFP
9:03 PM [usmle_guy] i just think of what i would think if i saw a newborn with an open spinal cord...."my....oh, sh...." which sounds like myeloschisis lol
9:03 PM [mmw] yes rox
9:03 PM [roxanita] uhm like a crisis, yeah
9:04 PM [usmle_guy] you have to do what you can to remember it
9:04 PM [mmw]
9:04 PM [roxanita] Glial cells are more like support cells right
9:05 PM [roxanita] like ependymal cells, astrocytes and oligodendrocytes
9:05 PM [clover] i think so rox
9:05 PM [mmw] glial cells r yes rox
9:06 PM [mmw] microglial cell is also glial cell but thone come from the mesoderm
9:06 PM [mmw] right rox?
9:06 PM [roxanita] what protein is responsible for the transport movement in the axon?
9:06 PM [mmw] i mean that one not thone miss typing
9:07 PM [mmw] kinesin
9:07 PM [roxanita] KINESISN right
9:07 PM [roxanita] I think so mmw, microglia arise from the monocytes
9:08 PM [roxanita] I mean KINESIN
9:08 PM [roxanita] Kinesin would be for the anterograde movement bu for the retrograde movement?
9:08 PM [mmw] lateral ventricles derived from ?
9:08 PM [mmw] dynein
9:08 PM [ttw] dynein
9:09 PM [ttw] telecep
9:09 PM [ttw] telencep
9:09 PM [usmle_guy] telenceph
9:09 PM [clover] agree
9:09 PM [mmw] yes
9:09 PM [mmw] and 3th V from?
9:09 PM [roxanita] what disease can affect the Retrograde movement?
9:10 PM [ttw] diencep
9:10 PM [clover] dienceph
9:10 PM [mmw] herpes,polio and tetanus toxin
9:10 PM [usmle_guy] diencephelon
9:10 PM [ttw] polio herpes tetanus
9:10 PM [mmw] yes diencep is correct
9:10 PM [clover] agree polio herpes tet
9:11 PM [roxanita] right guys but my question was bad formulated. the thing is...Because the Retrograde movement thanks to Dynein the neuron cell body will be affected in these diseases
9:11 PM [mmw] why r DM pt complaint of distal glove and stock weakness or sensory defectsdue to what failure?\
9:12 PM [roxanita] because these disease mostly affect the axons but because our helper Dynein it will go back to the cell body and destroy it
9:12 PM [usmle_guy] this was a qbank question.....which derivative is ADH from? telencephalon, dien, mesen, metenceph, myelenceph?
9:12 PM [ttw] axonal polyneuropathies
9:13 PM [roxanita] Diencephalon?
9:13 PM [clover] dienceph
9:13 PM [clover] something to do with osmostic damage of pns or something i think
9:13 PM [roxanita] could you please explain it mmw?
9:14 PM [mmw] yes axonal transport failure (axonal polyneuropathy)
9:14 PM [roxanita] cells in the hypothalamus produce ADH and Hypothalamus derivate from Diencephalon
9:14 PM [usmle_guy] yes, ADH is from post. pit.....which is from neurohypophysis and that is a derivative of the diencephalon....qbank question. :/
9:15 PM [mmw] which axonal transport causes neuron cell body damage by exogeneous substance?
9:16 PM [roxanita] yes it is stored in the post pit or neurohypophysis but let's not forget it is produced in the Hypothalamus
9:16 PM [roxanita] retrograde
9:17 PM [mmw] yes retrogade rox
9:17 PM [mmw] lateral Ventricles located in?
9:17 PM [usmle_guy] good point rox. ADH and oxycon are released in post pit but synthesized in hypothal
9:17 PM [ttw] telen
9:17 PM [roxanita] what is the problem in Multiple Sclerosis?
9:17 PM huli72 has left the chat.
9:18 PM [usmle_guy] problem with myelination in cns
9:18 PM [mmw] myelination defect
9:18 PM [roxanita] and which Cranial Nerve is affected in M.S. ?
9:18 PM [ttw] 2
9:18 PM [mmw] 2 optic N
9:19 PM [roxanita] right
9:19 PM [usmle_guy] any can be affected, but 1st is often the optic nerve
9:20 PM [mmw] which axonal transport use microtubles?antero,retro ,both ,none
9:20 PM [clover] rox cant ms effect any nerve in the cns?
9:20 PM [roxanita] I think is only II from the C.N. I mean
9:20 PM [mmw] i think on optic can be affected because on 2 N hace myelin
9:21 PM [mmw] only 2N hace myelin
9:21 PM [clover] thats the reason why its called MULTIPLE sclerosis.....because effects multiple sites of cns at different times
9:21 PM sanz has left the chat.
9:21 PM [ttw] both
9:21 PM [mmw] no other CN except 2 N i think
9:22 PM [mmw] yes ttw both antero and retro uses microtubule
9:22 PM [roxanita] it affects many segments of spinal cord but from the Cranial nerves only II, Am I right?
9:22 PM [mmw] yes i thin so rox
9:23 PM [ttw] i thinkso
9:23 PM [mmw] normal ph of CSF?
9:23 PM [clover] but i've seen an ms pt with 3rd and 6th cn damage. this is a very common presenting symptom causing ophtalmoplegia
9:23 PM [roxanita] what is polyhydramnios related with?
9:24 PM [mmw] anencephali
9:25 PM [ttw] 7.33
9:26 PM [usmle_guy] clover makes a good point. MS often has MLF or intraophthalmic something, which is a problem with CN 3 and 6
9:26 PM [roxanita] yes anencephaly b/c baby can't swallow right
9:27 PM [roxanita] I got to read about it clover
9:27 PM [mmw] in communicating hydrocephalus where can we seen the obstruction inside the ventricles or outside?
9:27 PM lanny has left the chat.
9:28 PM [ttw] outside
9:28 PM [mmw] i will check again too clover
9:28 PM megs has left the chat.
9:28 PM [usmle_guy] thx....i'll look it up too
9:29 PM [mmw] yes ttw outside is correct
9:29 PM strug has left the chat.
9:30 PM [usmle_guy] its communicating so outside
9:30 PM [mmw] what about the non-communicationg hydrocephalus inside or outside?
9:30 PM [mmw] yes usmle_guy
9:30 PM [ttw] in
9:30 PM [ttw] in
9:30 PM [usmle_guy] non communicating is usually in aqueduct
9:30 PM [usmle_guy] in
9:30 PM [clover] in
9:31 PM [mmw] yes
9:31 PM [clover] 3rd ventricle will probably be enlarged
9:32 PM step2 has left the chat.
9:32 PM [mmw] pt with urinary incontinence ,confusion,ataxia and enlarded ventricleswhat would u expect to his CSF pressure inc,dec ,or normal?
9:33 PM [ttw] normal
9:33 PM [mmw] yes
9:34 PM [clover] there is an increase in the amount of csf, why not an increase in pressure?
9:34 PM [mmw] i have one more q which i don't know Na+is inc in CSF or not?compare to serum
9:35 PM [mmw] good Q clover but i don't know the answer
9:36 PM [mmw] *choochoo*
9:36 PM [mmw] *harp*
9:36 PM [mmw] where r u guys
9:36 PM [mmw] hey
9:36 PM [usmle_guy] i know that the csf glucose is often less than serum glucose normally, but not sure about Na
9:37 PM [clover] trying to look up the answer for you mmw
9:37 PM [mmw] it say thanks to all my friends
9:37 PM [mmw] sorry
9:37 PM [roxanita] The compositionf for CSF?
9:38 PM [roxanita] I can't find about Na+ levels
9:38 PM [clover] i cant find the answer to that either
9:38 PM [mmw] i mean it says in page 324 in kaplan sodium is greater in serum and CSF is that means that both increase?
9:38 PM [roxanita] I know glucose is like 66% of serum glucose level
9:39 PM [usmle_guy] agree with rox. csf glucose about 2/3 of serum glucose. i have no idea about the Na
9:40 PM [mmw] i don't understand that sentence?pg 324 sentence18 can anyone tell me please?
9:40 PM [usmle_guy] sodium is greater than what?
9:41 PM [roxanita] Sodium 135 – 145 mEq/L, this is in blood
9:41 PM [roxanita] now compare with CSF
9:41 PM buttercup has left the subroom.
9:42 PM [clover] welcome back butter
9:42 PM [roxanita] ok that's homework
9:42 PM [mmw] oh it means Na less in in CSF compare to serum is that correct?
9:43 PM [roxanita] now, what are the features of CSF in Bacterial meningitis x.e?
9:43 PM [roxanita] how is the glucose? lower or higher?
9:43 PM [mmw] Mg and Cl- in CSF inc ordec ?
9:43 PM [mmw] glucose is dec
9:44 PM [usmle_guy] total cell count 1000 to 20,000, >90% polys, decreased glucose, increase prot
9:44 PM [roxanita] what about proteins?
9:44 PM [clover] dec gluc, inc prot
9:44 PM [mmw] in bacterial meningitis bacteria usedoes not usse glucose to synthesis protein so glu dec
9:45 PM [roxanita] yes, in bacterial meningitis: PMN>1000 ; Protein elevated >100mg/dl, glucose reduced......right guys
9:45 PM [mmw] but in viral meningitis virus use glucose to synthsis protein so glucose dec and protein inc i think
9:45 PM [roxanita] right
9:46 PM [roxanita] In viral isn't it normal?
9:46 PM [clover] normal glucose in viral usually
9:46 PM [roxanita] yes, that's what I knew :/
9:46 PM [mmw] yes yes
9:46 PM [usmle_guy] some exceptions like mumps and herpes, but normal gluc
9:47 PM [mmw]
9:47 PM [roxanita] ok
9:47 PM [usmle_guy] but dont be fooled by the numbers compared with the serum because the glucose in the csf is normally lower than serum....but doesn't mean low
9:48 PM [mmw] ok usmle_guy
9:48 PM [roxanita] yup, CSFgluc=66%BLOODgluc
9:48 PM [usmle_guy] especially when you run across that question in qbank because it got me :<
