The circular muscle located directly behind the iris of the eye.
produces the clear, watery aqueous humor that fills the anterior cavity of the eye.
Tissues located around the lens of the eye that supply fluid to nourish the eye.
(SIHL-ee-uh-ree): A structure near the angle that produces aqueous fluid. See glaucoma.
structure located behind iris, composed primarily of the ciliary muscles
one of the three portions of the vascular tunic of the eyeball, the others being the choroid and the iris; includes the ciliary muscle and the ciliary processes
a structure located behind the iris that produces a clear fluid known as the aqueous humor.
A structure located behind the iris (rarely visible) which produces aqueous fluid that fills the front part of the eye and thus maintains the eye pressure. It also allows focusing of the lens.
an annular (ring-like) structure on the inner surface of the anterior wall of the eyeball, contained within the uveal tract and composed largely of the ciliary muscle and bearing the ciliary processes
A thickened region of the choroid that encircles the lens of the eye; includes the ciliary muscle and the ciliary processes that support the suspensory ligaments of the lens.
Present in anterior chamber of eye; secretes aqueous humor.
The intraocular eye muscles that change the shape of the lens.
Located just behind the iris, contains circular muscle fibers and longitudinal muscle fibers, controlling focusing of the eye and the production of aqueous fluid.
The portion of the uveal tract between the iris and the choroid; composed of ciliary muscle and processes.
the part of the tunic of the eye between the choroid coat and the iris
An eye muscle that controls the shape of the lens to enable the eye to quickly change focus to see objects at near, intermediate and far distances.
ring-like structure lying behind the iris which holds the natural lense in its position and, at the same time, ensures a stable intraocular pressure by producing the eye water.
The part of the eye that connects the choroid to the iris. It produces aqueous fluid that fills the front part of the eye and thus maintains the eye pressure. It also allows focusing of the lens.
the ring of muscle fibers that holds the lens of the eye. It also helps control intraocular pressure.
Part of the eye that produces aqueous humor and maintains eye pressure. It also is attached to the lens and aids in accommodation (the ability to focus between distant objects and near objects).
Tissues behind the eye, which keep it secured and in place.
SIL-ee-air-ee BOD-ee A highly folded, specialized structure in the center of the choroid coat of the human eye that houses the ciliary muscle, which alters the shape of the lens. 648
a ring of tissue between the iris and the choroid consisting of muscles and blood vessels that changes the shape of the lens and manufactures aqueous humor
the thickened area of the vascular layer of the eye, connecting the choroid and iris
Part of the eye, the ciliary body is a thin vascular (blood vessel-filled) middle layer of the eye that is situated between the sclera (the white of the eye) and the retina (the nerve layer that lines the back of the eye, senses light, and creates impulses that travel through the optic nerve to the brain). See the entire definition of Ciliary body
the part of the eye that produces aqueous humor.
Silly-Airy Body] An organ located right behind and encircling the iris. Tumors can come from the vascular and non-vascular parts of the ciliary body. The ciliary body also makes fluid which fills the eye.
Made up of ciliary muscle which helps the accomodation of the lens and controls the intraocular pressure of the eye. It is also where the aqueous is made.
Part of the eye between the iris and the choroid; the three form the uvea. The ciliary body's main functions are accommodation, aqueous humor production and holding the lens in place.
An extension of the uvea which is comprised of the ciliary muscle and ciliary process. Its function is to assist in the changing of the crystalline lens in the act of accomodation.
Analagous to the choroids plexus of the brain. Secretes aqueous humor. Through zonule fibers supports the lens.
Part of the eye that contains a focusing muscle and connective tissue.
the structure that focuses the lens and produces the fluid inside the front of the eye.
Produces aqueous humor and contains the ciliary muscle.
an annular structure on the inner surface of the anterior wall of the eyeball. It is mainly composes of the ciliary muscle (important for accomodation) and ciliary process (vascular network attached to the ligament suspending the lens).
Tissues located around the lens of your eye that produce the aqueous fluid that nourishes the eye.
It is a structure which consists of the ciliary processes and ciliary muscles. The ciliary body produces aqueous, which provides nutrients to the eye and maintains ocular pressure. The ciliary muscles provide the focusing ability of the eye.
A structure in the eye that contains muscles which will affect the focusing of the lens.
the thickened part of the vascular tunic of the eye that joins the iris with the anterior portion of the choroid. Picture in Mosby Dictionary page 337).
The ciliary body is the circumfrential tissue inside the eye composed of the ciliary muscle and ciliary processes.Cassin, B. and Solomon, S. Dictionary of Eye Terminology. Gainsville, Florida: Triad Publishing Company, 1990.
