Iris
A
= pigmented tissue, sphincter
• control the amount of light entering the eye
5
Q

A
= ligaments connecting the ciliary muscle and the lens
• involved in controlling accommodation (focusing)
6

Ciliary muscle
A
= ring of muscle connected to lens via suspensory ligaments
• controls accommodation (focusing)
7
Q
