middle vascular tunic
The opaque middle layer of the eyeball is called the choroid. It is rich in blood vessels and helps to supply nutrients and oxygen to the retina, which is the light-sensitive layer at the back of the eye.
As the sclera and choroid reach the front part of the eye, they become thinner and more transparent. The sclera thins out to form the cornea, which is the clear outermost layer of the eye that allows light to enter. The choroid also becomes thinner and gives way to the ciliary body and iris in the front part of the eye.
The part of the eye that begins with the letter "u" is the uvea. The uvea is the middle layer of the eye that includes the iris, ciliary body, and choroid.
The iris is contained within the middle layer of the eye known as the uvea, which includes the choroid, ciliary body, and the iris. The iris is the colored part of the eye that surrounds the pupil and regulates the amount of light entering the eye by controlling the size of the pupil.
The uvea is located in the middle layer of the eye, beneath the white outer sclera and the inner retina. It includes the iris, ciliary body, and choroid, which are all important for regulating light entering the eye, focusing vision, and providing nourishment to the eye's structures.
Choroid
iris and ciliary muscles
Choroid
ciliary body
One of the two muscles that make up the front part of the choroid is the ciliary muscles. Another one that makes up the choroid is the iris.
The uveal tract is composed of the iris, ciliary body, and choroid. The iris is the colored part of the eye that regulates the amount of light entering the eye. The ciliary body produces aqueous humor, which nourishes the eye and maintains its shape. The choroid is a vascular layer that provides oxygen and nutrients to the retina.
The opaque middle layer of the eyeball is called the choroid. It is rich in blood vessels and helps to supply nutrients and oxygen to the retina, which is the light-sensitive layer at the back of the eye.
The correct order of the layers of the eyeball from the outside to the inside is the sclera (white part), choroid, retina (consisting of the outer pigmented layer and the inner neural layer).
As the sclera and choroid reach the front part of the eye, they become thinner and more transparent. The sclera thins out to form the cornea, which is the clear outermost layer of the eye that allows light to enter. The choroid also becomes thinner and gives way to the ciliary body and iris in the front part of the eye.
the ciliary muscle is the smooth muscle of the ciliary body
The part of the eye that begins with the letter "u" is the uvea. The uvea is the middle layer of the eye that includes the iris, ciliary body, and choroid.
the iris!!! iris is the coloured part of your eye,and its a muscle that controls your pupil(the black dot) to let how much light you're eye needs. The iris regulates the amount of light by controlling the size of the pupil.
