Anatomy of the Eye Quiz

Eye Structures and Functions

• The trabecular meshwork actively pumps fluid out of the substantia propria to prevent over hydration and opacity.

Retinal Layers

• The retinal pigment epithelium (RPE) separates the retina from the choroid and contains a layer of pigmented epithelial cells on a basement membrane called Bruch's membrane.

Accessory Structures

• The function of accessory structures of the eye is to support and protect the eye.
• The conjunctiva, an accessory structure, produces mucus to lubricate and moisten the eye.

Ciliary Body and Processes

• The ciliary body produces the aqueous humor and maintains the shape of the lens.
• The function of the ciliary processes is to produce the aqueous humor.

Aqueous Humor

• The composition of the aqueous humor includes water, ions, sugars, and ascorbic acid.

Photoreceptors

• The primary function of rods and cones is to convert light into electrical signals that are transmitted to the brain.

Uveal Tract

• The choroid, a layer of the eye, contains numerous large melanocytes that absorb light and prevent interference from refraction.
