Question

damage to the medial rectus muscles would probably affect

a) pupil constriction

b) accommodation

c) convergence

d) refraction

Explanation:

The medial rectus muscles are responsible for eye movement. Convergence is the process where both eyes turn inward to focus on a near object, and the medial rectus muscles play a key role in this. Pupil constriction is mainly related to the iris muscles. Accommodation (focusing of the lens) is related to the ciliary muscles. Refraction is about how light is bent as it passes through the eye's structures (cornea, lens etc.).

Answer:

C. convergence
