Damage to the medial rectus muscles would probably affect________.
A) convergence
B) pupil constriction
C) refraction
D) accommodation

Question

Quizplus · Accepted Answer

The medial rectus muscles are responsible for inward eye movements, or convergence. Therefore, damage to these muscles would affect convergence. Pupil constriction is controlled by the pupillary sphincter muscle, which is not related to the medial rectus muscles. Refraction is controlled by the shape of the lens in the eye, and accommodation is controlled by the ciliary muscle in the eye, which are also not related to the medial rectus muscles.
