Ciliary body: anatomy and function - Kenhub
Oct 30, 2023 · The ciliary body is an inner eye structure, located at the border between the choroid and the iris. It is composed of several unique structures that give the ciliary body its unique shape and function.
Ciliary body - Wikipedia
The ciliary body is a ring-shaped thickening of tissue inside the eye that divides the posterior chamber from the vitreous body. It contains the ciliary muscle, vessels, and fibrous connective tissue. Folds on the inner ciliary epithelium are called ciliary processes, and these secrete aqueous humor into the posterior chamber. The aqueous humor ...
Basic Histology of the Eye and Accessory Structures - EyeWiki
The medial surface of the ciliary body that projects towards the lens is folded into small projections called ciliary processes. The ciliary processes are covered by 2 layers of epithelium: The inner layer is a pigmented layer of simple columnar epithelium that is rich in melanin.

The ciliary body functions primarily to control the shape of the lens and produce aqueous humor. Just behind the iris, the surface of the ciliary body is thrown into folds known as ciliary processes.

Feb 1, 2014 · Ciliary body has 3 distinct bundles of smooth muscle which assist in accommodation; as muscle contacts, ciliary body extends forward, reducing pressure on zonules, enabling lens to become less concave, thereby increasing its refractive power

May 1, 2023 · The uvea is the vascular layer in the middle, subdivided into the iris, ciliary body, and choroid. The retina constitutes the innermost layer and is made up of nervous tissue. All of these layers can further subdivide and undergo histological classification.
Ciliary Body and Ciliary Epithelium - PMC - PubMed Central (PMC)
In the eye, the ciliary epithelium bilayer forms a barrier between a part of the body that is one of the most densely vascularized and a part of the body that has no blood vessels at all. One of the unique features of the eyeball is the absence of blood in the optical pathway.

May 3, 2023 · Histology. The ciliary body contains two layers of cuboidal epithelium. The deep layer is heavily pigmented due to high vascularity and high level of melanin. The surface layer is non-pigmented, non-photosensitive extension of the receptor layer of the retina and is responsible for aqueous humor production 3.
The ciliary body is the site of aqueous humor production and it is totally involved in aqueous humor dynamics. The ciliary body is the anterior portion of the uveal tract, which is located between the iris and the choroid. (figure 1) Figure 1. Histology of human ciliary body (courtesy Prof. Ruth Santo)

Jan 24, 2024 · The ciliary body forms a complete ring around the iris. It is a ring of smooth muscle that holds the lens in place via the suspensory ligaments and controls the shape of the lens. In cross-section, the ciliary body is triangular. It is made up of 3 parts: ciliary epithelium, ciliary stroma and ciliary muscle.
