cycl/o (6/24)

List item

cycl/o is a combining form that refers to “ciliary body” or “ciliary muscle”.

Ciliary body is a circular structure that is attached to the iris, the colored part of the eye. Fluid called aqueous humor is produced by the ciliary body in the eye. In addition, it contains the ciliary muscle, which changes the shape of the lens when you focus on a close object. It is called accommodation when this happens.
