Question: What is the ciliary body and what two functions does it serve?

Answer: the ciliary body is a circular band of muscle that is connected and sits immediately behind the iris. It does two things:

1. Controls lens shape by pulling or relaxing on the lens zonules
2. Produces aqueous humor which fills the posterior and anterior chambers and provides nutrition for avascular tissues in the eye such as the cornea.
