What is the predominant type of collagen found in the vitreous body of the eye?

The vitreous body of the eye primarily contains Type 2 collagen, which is essential for its structure and function. Type 2 collagen is mainly associated with cartilage and, in the eye, contributes to the jelly-like consistency and mechanical stability of the vitreous humor. This type of collagen forms a framework that provides support and maintains the shape of the vitreous body, allowing it to effectively fill the space between the lens and the retina.

Other collagen types mentioned in the options have different roles and locations in the body. Type 1 collagen is abundant in skin, tendons, and bone, serving primarily in providing tensile strength. Type 3 collagen is found in reticular fibers and is important in providing support in soft tissues and organs. Type 4 collagen is specific to basal membranes, contributing to the filtration and structural functions of tissues. Therefore, these types do not play a significant role in the composition of the vitreous body as Type 2 collagen does.
