    Superior Oblique muscle

    Advertisements



    I have found in many different books, different functions of this muscle. I need to know which one is the right one.

    Down and in (nasaly)
    Down and out (temporal)
    When the eye is aducted the SOM moves the eye Down
    When the eye is in its central position the SOM moves it Down and out.

    I find it really hard to understand why in different books there are different answers. If it is possible check this information in this books.
    • Harrisons principles of internal medicine
    • Current pathophysiology
    • Moores anatomy
    • Adams neurology
    • and a lot more books have different answers for this simple muscle

    The superior rectus muscle can elevate and adduct the eye from the neutral position. From the abducted position it is the ONLY muscle that can elevate the eye!!!
    The inferior oblique muscle can elevate and abduct the eye from the neutral position. From the adducted position it is the ONLY muscle that can elevate the eye!!!
    The inferior rectus muscle can depress and adduct the eye from the neutral position. From the abducted position it is the ONLY muscle that can depress the eye!!!
    The lateral rectus muscle can abduct the eye.
    The superior oblique muscle can depress and abduct the eye from the neutral position. From the adducted position, it is the ONLY muscle that can depress the eye!!!
