Question

State the exact location of the following structures:

Ciliary body

Answer 1

Ciliary body:

1. The thin layer that is present in the terminal region of the choroid, at the junction of the sclera and cornea of the human eyeball is known as the ciliary body.
2. The thin fibers projecting from the ciliary body are known as suspensory ligaments (they hold the lens in position).

Function:

1. The ciliary body helps to alter the shape of the lens by contraction and relaxation.
2. The lens becomes spherical due to the contraction of the ciliary body.
3. The lens becomes elongated due to the relaxation of the ciliary body.
