The outer covering of the eye is formed by?
The outer covering of the eye is formed by the cornea and sclera. The cornea is the transparent layer at the front of the eye, while the sclera is the white, tough, outer layer that covers the rest of the eyeball. These structures help protect and maintain the shape of the eye.
What is the opague middle layer of the eyeball?
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.
What is the anterior portion of the eye?
The anterior portion of the eye includes structures like the cornea, iris, pupil, and anterior chamber. These structures play a crucial role in allowing light to enter the eye and focusing it onto the retina.
What is the protective layer over the eye called?
There are two layers that protect the eye. One is called the cornea, and it is at the front of the eye. The second one is called the sclera, and it wraps around the whole eyeball. If you are still not sure, look up some diagrams of the eye or parts of the eye.
What is hypermyopia?
Extreme short sightedness Hypermyopia is Retinal Detachment The retina is attached to the sclera in the back of the eye, and a retinal detachment occurs when it is pulled away from this normal position. The retina, like film in a camera, is responsible for creating the images that one sees. A good picture could not be produced if the film were not in its correct location within the camera, and we lose vision if the retina is not in its proper place within the eye. The retina detaches by separating from the back wall of the eye. When it is removed from its blood supply (the choroid), it will lose nourishment and result in a loss of some vision if not repaired in time. This retinal tear may be caused by trauma or by a vitreous detachment (or "posterior vitreous detachment"). Vitreous detachment, not uncommon in older people, results from the vitreous fluid shrinking and pulling away from the retina. This causes "floaters," which do not damage the retina or vision.

How does the nature of the sclera and choroid change as they reach the front part of they eye?
I think this is correct! The sclera turns into the cornea, which is the transparent portion of the eye. The choroid also becomes transparent to allow more light into the eye.
What is the extra layer of reflecting cells behind the retina?
The choroid layer lies behind the retina and in front of the sclera. It carries oxygen and other necessary nourishment to the retina.
Which two involuntary muscles are located in the front part of the choroid?
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.
What is the Front part of the coat is the ciliary muscle and iris?
Choroid
What is the transparent outermost part of the eye?
The ocular structures most resistant to direct injury are the cornea (the clear front of the eye) and the sclera (the white part of the shell around the eye). The cornea and the sclera are contiguous.
The clear circular window in the front of the eye is the sclera?
False.
What is an involuntary muscle that makes up the front part of the choroid?
ciliary body
Are the iris and ciliary muscles located in the front part of the choroid muscles Involuntary?
iris and ciliary muscles

What is the front transparent part of the sclera called?
The front transparent part of the sclera is called the cornea. It serves as the eye's primary lens, allowing light to enter and helping to focus images onto the retina. The cornea also provides protection to the inner structures of the eye and plays a crucial role in vision.
what protects our lens?
Image result for what protects our lens The sclera (SLEER-uh) is the protective layer. This tough, fibrous tissue surrounds the eyeball and attaches to the cornea, which is the clear front surface of the eye. What we see as the white of the eye is the sclera. Over the sclera lies the conjunctiva, a clear skin layer that protects the eye from becoming dry.
What is the opague middle layer of the eyeball?
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.
