The term that refers to the major layered structures of the eye, including the sclera, choroid, and retina?

• A. Layers of the eye
• B. Accessory structures of the eye
• C. Tissues of the retina
• D. Layers of the cornea

Answer: (A)

Think of the eye as built from three main layers that form its wall: the outer fibrous layer where the sclera resides, the middle vascular layer containing the choroid, and the inner neural layer that is the retina. Describing these as “layers of the eye” captures this broad, organized structure from the outer to the inner part. It fits because the sclera, choroid, and retina are the major components that make up the eye’s layered walls. The other options point to more specific or different groups—layers of the cornea would only cover the cornea itself, tissues of the retina would refer just to the inner retinal tissue, and accessory structures refer to parts like the eyelids and glands—so they don’t describe the overall layered arrangement that includes sclera, choroid, and retina.
