2023年10月30日 · The ciliary muscle occupies the biggest portion of the ciliary body, which lies between the anterior border of the choroid and iris. It is composed of smooth muscle fibers oriented in three different directions; longitudinal, radial and circular.

The ciliary muscle is an intrinsic muscle of the eye formed as a ring of smooth muscle [3] [4] in the eye's middle layer, the uvea (vascular layer). It controls accommodation for viewing objects at varying distances and regulates the flow of aqueous humor into Schlemm's canal.

What does the ciliary body of the eye do? The ciliary body has two main jobs: To make aqueous fluid and to change the shape of your lens while your eye is focusing. The aqueous fluid, also called aqueous humor, is clear and takes up the space between your cornea and iris.

2025年1月22日 · The ciliary muscle is a ring of smooth muscle fibers in the eye that controls the shape of the lens, playing a crucial role in focusing (accommodation). It is part of the ciliary body, which also produces aqueous humor.

2023年8月8日 · The zonular fibers are in contact with the ciliary muscle, which is a circular band of smooth muscle that controls the tightness of the zonular fibers. The ciliary muscle alters the tightness of the zonular fibers by contracting and relaxing, thereby altering the shape of the lens and leading to the adaptation to near or far vision.

2023年8月7日 · The ciliary muscle is a smooth muscle ring that controls accommodation by altering the shape of the lens, as well as controlling the flow of aqueous humor into Schlemm's canal. The ciliary muscle is attached to the zonular fibers, which suspend the lens.

2023年10月30日 · The ciliary muscle is in charge of changing the shape of the lens, while the ciliary processes participate in the production of the fluid in the eye also known as the aqueous humor. The ciliary body is attached to the lens by the collection of …
