What is the composition of the vitreous body?

• A. A thick gel-like substance
• B. A watery fluid
• C. A dense network of fibers
• D. A solid structure

Answer: (A)

The vitreous body, located in the eye, is primarily composed of a thick gel-like substance. This gel is mostly water but is unique in that it also contains collagen fibers and hyaluronic acid, which together create a jelly-like consistency. The gel-like nature of the vitreous body is crucial, as it helps maintain the shape of the eyeball and supports the retina by keeping it in place against the choroid. While the options suggesting watery fluid, a dense network of fibers, and a solid structure pertain to components or characteristics of other parts of the eye or bodily structures, they do not accurately describe the overall composition of the vitreous body. The correct description captures its essential qualities and functionality in the eye.
