Ciliary body of eye, SEM Featured October Print

Ciliary body of eye, SEM

Ciliary body of eye. Coloured scanning electron micrograph (SEM) of the ciliary body of a human eye. The ciliary body is a circular band of tissue that surrounds and supports the lens. It contains the ciliary muscles, which contract and relax to alter the curvature of the lens in order to focus light onto the retina. This process is known as accommodation.
