hi understanding the actions of theextra ocular muscles can be frustratingly confusing so i hope this video helpsyou may also want to watch the video on eye movement terminology before this one the eye sits within the bony orbit the orbit has a roof
How To Animate Head Bobbing, a floor, medial wall and lateral wall it is therefore somewhat pyramid like inshape the two orbits have medial walls which run parallel to one another the lateral walls are about forty-fivedegrees to the media walls, or about ninety
degrees to one another the eye sits within the middle of thisspace with the for recti muscles converging on the orbital apex wherethey insert into the annulus of zinn a fibrous ring of tissue that in circlesthe optic nerve these recti are superior rectus medial rectus and inferior rectus all supplied by the oculomotor or third cranial nerve and lateral rectus supplied by the abducens or sixth cranial nerve the inferior oblique is also supplied bythe oculomotor nerve
while the superior oblique is supplied bythe trochlea or fourth cranial nerve contraction of the lateral rectus a taxii ball contraction of the media rectus abduct c l_ i_ the two opposing muscles are describedas being antagonists sharon tinsel orf reciprocal innovationstates that when a master's stimulated its entire canisters inhibited this means abductions a combination ofcontraction of the lateral rectus and relax ation of the media rectus as well as having an antagonist musclethere's also a joke muscle
