Question 1

Extraocular muscles functions:

1. Med rectus
2. Lat rectus
3. Sup rectus
4. Infer rectus
5. Sup oblique
6. Infer oblique

Answer 1

1. Med rectus: adducts
2. Lat rectus: abducts
3. Sup rectus: elevates, adducts, int rotates
4. Infer rectus: depresses, adducts, ext rotates
   More powerful when in lateral
   Recti arise from fibrous common tendinous ring
5. Sup oblique: depresses, abducts, int rotates
6. Infer oblique: elevates, abducts, ext rotates

Also levator palpebral superioris

Via oculomotor, trochlear, abducens LR6SO4
Also optic nerve, and opthalmic division of trigeminal nerve supply structures in orbit

Opthalmic artery supplies orbit, giving off central artery which supplies retina. Opthalmic veins drain to cavernous venous sinus
