Question

Quizplus · Accepted Answer

The muscles that control the movement of the eyeball in the socket are called extrinsic muscles. They are called extrinsic muscles because they originate from outside the eye and attach to the sclera (white part of the eye). These muscles allow the eye to move horizontally, vertically, and diagonally. Intrinsic muscles, on the other hand, are located within the eye and control the pupillary size and lens shape. Ciliary muscles are intrinsic muscles that control the shape of the lens, and socket muscles is not a commonly used term in describing the muscles of the eye.
