Which of the following components is NOT part of the uvea?

• A. Iris
• B. Ciliary body
• C. Cornea
• D. Choroid

Answer: (C)

The uvea is a crucial part of the eye that is responsible for providing blood supply and nourishment to the eye tissues. It consists of three primary components: the iris, the ciliary body, and the choroid. The iris is the colored part of the eye that regulates the amount of light entering through the pupil. The ciliary body is a structure that produces aqueous humor and contains muscles that control the lens's shape for focusing. The choroid is a vascular layer between the retina and the sclera that provides oxygen and nutrients to the outer layers of the retina. The cornea, on the other hand, is the clear, dome-shaped front surface of the eye that covers the iris and pupil. It is part of the outer layer of the eye and is not involved in the uvea. The cornea plays a significant role in focusing light onto the retina but does not participate in the vascular or pigmentary functions associated with the uveal tract. Therefore, identifying the cornea as not being part of the uvea is correct.
