8. Organs of Special Senses – ii

The ciliary body is a circular structure that is an extension of the iris, the colored part of the eye. 

The ciliary body produces the fluid in the eye called aqueous humor. 

It also contains the ciliary muscle, which changes the shape of the lens when your eyes focus on a near object.

The ciliary body has three functions: accommodation, aqueous humor production and resorption, and maintenance of the lens.

Accommodation essentially means that when the ciliary muscle contracts, the lens becomes more convex, generally improving the focus for closer objects and vice versa.

Aqueous humor, which is responsible for providing oxygen, nutrients, and metabolic waste removal to the lens and the cornea, which do not have their own blood supply.

The zonular fibers collectively make up the suspensory ligament of the lens. These provide strong attachments between the ciliary muscle and the capsule of the lens.
