what is the purpose of the orbital muscles
The extraocular muscles are the six muscles that control movement of the eye (there are four in bovines) and one muscle that controls eyelid elevation (levator palpebrae).The actions of the six muscles responsible for eye movement depend on the position of the eye at the time of muscle contraction.ive of the extraocular muscles have their origin in the back of the orbit in a fibrous ring called the annulus of Zinn: the four rectus muscles and the superior oblique muscle.
