Which Structure is Affected by the Contraction and Relaxation of the Ciliary

Question

Which structure is affected by the contraction and relaxation of the ciliary muscles?
A) Cornea
B) Lens
C) Macula lutea
D) Optic chiasm

Accepted Answer

The contraction and relaxation of ciliary muscles affect the shape of the lens, allowing it to adjust and focus on objects at different distances. The cornea is not directly affected by the ciliary muscles, and the macula and optic chiasm are not part of the mechanism for adjusting the lens.
