Question

Which of the following statements is true of the cillary body of the eye?

(A) It contains muscles that help assist in control the thickness and size of the lens
(B) It produces a vitreous humor that fills the posterior chamber of the eye
(C) The suspensory ligaments create the color of iris
(D) It is involved in controlling the amount of light that is allowed into the eye

Answer 1

The true statement about the ciliary body is that it contains muscles that assist in controlling the thickness and size of the lens, allowing the eye to focus light onto the retina.

Step-by-step explanation:

The statement about the ciliary body of the eye that is true is (A) It contains muscles that help assist in controlling the thickness and size of the lens.

The ciliary body is a muscular structure located within the eye's vascular tunic layer, which also includes the choroid and iris. The choroid is a highly vascularized connective tissue that supplies blood to the eyeball. The ciliary body is equipped with muscles that connect to the lens of the eye via suspensory ligaments, also known as zonule fibers. These muscles and fibers enable the ciliary body to change the shape of the lens, thereby focusing light onto the retina at the back of the eye. This process is vital for adjusting the eye's focus to see objects at various distances.
