Question

multiple choice question
the transparent, elastic structure of the eye which changes shape in response to contraction by ciliary muscles is the
o cornea
o ciliary body
o lens
o choroid coat
o pupil

Explanation:

The lens of the eye is a transparent, elastic structure. Ciliary muscles can contract or relax to change the shape of the lens, adjusting its focal length for near and far - vision. The cornea is the front - most transparent part but is not adjusted by ciliary muscles in this way. The ciliary body contains the ciliary muscles but is not the structure that changes shape. The choroid coat is a vascular layer of the eye and not related to this function. The pupil is the opening in the iris and controls the amount of light entering the eye, not a shape - changing elastic structure in response to ciliary muscles.

Answer:

C. lens
