Question

Quizplus · Accepted Answer

The extrinsic muscles are responsible for moving the eyeball from side to side. The other choices are not involved in this movement. The iris controls the size of the pupil, the ciliary muscle controls the shape of the lens for focusing, and there are no intrinsic muscles in the eye that are involved in movement.
