State five functions of ciliary body?

1. Production of aqueous humor: The ciliary body is responsible for producing the aqueous humor, a clear fluid that fills the anterior chamber of the eye. This fluid helps maintain the shape of the eye and provides nutrients to the cornea and lens.

2. Accommodation: The ciliary body plays a crucial role in the process of accommodation, which allows the eye to focus on objects at different distances. It adjusts the shape of the lens by contracting or relaxing the ciliary muscles, thereby changing the lens' curvature and enabling near or far vision.

3. Regulation of intraocular pressure: The ciliary body helps regulate the intraocular pressure by controlling the production and outflow of aqueous humor. It adjusts the rate of fluid production to maintain a balance between its production and drainage, preventing an increase or decrease in intraocular pressure.

4. Nutrient supply: The ciliary body supplies essential nutrients, such as oxygen and glucose, to the lens and cornea. These nutrients are necessary for maintaining the health and function of these structures.

5. Production of mucus: The ciliary body produces mucus that helps lubricate the surface of the eye, preventing dryness and irritation. This mucus is secreted by the ciliary processes and helps protect the eye from foreign particles and pathogens.
