A ciliary muscle is actually either of two distinct groups of muscle fibers that make up the ciliary muscles. They are found, together with many radiating folds called ciliary processes (or networks), within the ciliary body–the thickest part of the middle layer of the eye, which extends forward from the choroid and forms an internal ring around the front of the eye.
