Ciliary muscle: Origin, insertion, innervation, function - Kenhub
2023年10月30日 · The layers of ciliary muscle are described differently by several authors in the literature, but the most used classification divides this muscle into three separate layers; The longitudinal layer is the outermost muscle layer situated adjacent to the …
Ciliary muscle - Wikipedia
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 .

2023年8月8日 · Seven anterior ciliary arteries supply the conjunctiva, sclera, and rectus muscles. Six extrinsic eye muscles move each eye: the superior rectus, inferior rectus, lateral rectus, medial rectus, superior oblique, and inferior oblique. These muscles are important for moving the eyes as they place an image on the fovea to get maximum resolution.
Ciliary muscle - Structure, Location, Function, Anatomy
4 天之前 · The ciliary muscle is made up of smooth muscle fibers arranged in three distinct orientations, each contributing to the muscle’s overall ability to change the shape of the lens: Longitudinal (Meridional) Fibers. The longitudinal fibers are the outermost layer of …
Ciliary body: anatomy and function - Kenhub
2023年10月30日 · 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. These structures include the ciliary muscle, ciliary processes, ciliary vessels and ciliary epithelia.

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.
Ciliary muscle - e-Anatomy - IMAIOS
The Ciliary muscle (m. ciliaris; Bowman's muscle) consists of unstriped fibers: it forms a grayish, semitransparent, circular band, about 3 mm. broad, on the outer surface of the fore-part of the choroid. It is thickest in front, and consists mainly of two sets of fibers, meridional and circular. Longitudinal and radial fibers are also described.
Anatomy Of The Ciliary Body - INSIGHT OPHTHALMOLOGY
2024年1月20日 · In this post we focus on mastering clinical anatomy of the ciliary body. We discuss the macroscopic parts, pars plana and pars plicata; microscopic 5 layers of the ciliary body and its important muscle, ciliaris. We deep dive into the ciliaris parts and its role in accommodation and aqueous drainage.
The ciliary muscle consists of three separate muscle fibers: longitudinal, circular and oblique. The longitudinal fibers (meridional), which are the most external, attach the ciliary body anteriorly to the scleral spur and trabecular meshwork at the limbus, and posteriorly to

2022年10月24日 · The ciliary muscle (TA: musculus ciliaris) is located within the ciliary body of the eye. It acts to facilitate lens accommodation for near vision, and receives parasympathetic innervation from short ciliary nerves, arising from the oculomotor nerve via the ciliary ganglion.
