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

Question

Quizplus · Accepted Answer

The medial rectus muscles are responsible for moving the eye inward toward the nose, which is important for convergence (the ability to bring both eyes together to focus on a near object). Damage to the medial rectus muscles could therefore affect convergence. Pupil constriction is controlled by the iris muscles, accommodation is controlled by the ciliary muscles, and refraction is primarily controlled by the shape of the lens. While damage to the medial rectus muscles could potentially affect these processes indirectly, it is not a direct influence.
