Function Of Ciliary Body

Accommodation aqueous humor production and resorption and maintenance of the lens zonules for the purpose of anchoring the lens in place. The ciliary body has three functions.

The surface is thrown into folds called ciliary processes read more.

Function of ciliary body. The eye s cillary body carries out three essential functions. The ciliary body receives its parasympathetic nerve supply from the oculomotor nerve the third cranial nerve. Together with the sphincter pupillae the ciliary muscle functions are mainly instructed by the parasympathetic nerve fibers of oculomotor nerve cn iii.

The ciliary body is part of the uvea which also includes the iris the circular colored curtain of the eye that surrounds the pupil and the choroid of the eye which is the thin vascular middle layer. The ciliary body is a circular structure that is an extension of the iris the colored part of the eye. A critical structure within the eye the ciliary body performs three essential functions it supports the lens focuses on a near target and produces inner eye fluid.

It also contains the ciliary muscle which changes the shape of the lens when your eyes focus on a near object. Part of the eye the ciliary body is a circular structure just behind the iris composed of the ciliary muscle and ciliary processes which attach to the lens. Controls lens shape by pulling or relaxing on the lens zonules.

The ciliary body is the forward continuation of the choroid. The ciliary body is divided into an anterior pars plicata and posterior pars plana. The ciliary processes secrete the aqueous fluid and the ciliary muscle modifies focus by changing the shape of the lens.

This process is called accommodation. It does two things. The ciliary body is a circular band of muscle that is connected and sits immediately behind the iris.

Smith s anesthesia for infants and children eighth edition 2011. The ciliary body produces the fluid in the eye called aqueous humor. The contraction of the ciliary muscle loosens the zonular fibers increasing the convexity of the lens which induces accommodation for near vision.

It is a muscular ring triangular in horizontal section beginning at the region called the ora serrata and ending in front as the root of the iris. The ciliary body is responsible for aqueous humor production and outflow secretion of hyaluronic acid into the vitreous and lens accommodation. It is also a critical component of the blood aqueous barrier.

The ciliary body is the site of aqueous humor production and contains the ciliary muscles that are responsible for accommodation of the lens.
