Description
The eyes are the organs of vision in the human body.
There is a pair of eyes in every person.
The eye is located in the orbits of the skull above the nose.
The eye is made up of:
1. eyeball
The eyeball is a slightly asymmetrical globe, about an inch in diameter.
The eye is made up of three layers:
1. The outer fibrous layer is composed of the cornea and sclera.
2. The middle vascular layer consists of the choroid, ciliary body and iris.
3. The innermost neural layer is the retina
The retina gets its circulation from the vessels of the choroid as well as the retinal vessels.
The retina contains the rods and cones which act as photoreceptors that transmit received images to the brain through the optic nerve.
Within these layers are
1. the aqueous humor,
The aqueous humor is a clear fluid that is contained in two areas:
a. the anterior chamber between the cornea and the iris, and
b. the posterior chamber between the iris and the lens.
2. the vitreous body,
The vitreous body is a clear jelly that is much larger than the aqueous humor present behind lens and the rest, and is bordered by the sclera, zonule, and lens.
They are connected via the pupil.
3. the flexible lens.
The lens is suspended to the ciliary body by the suspensory ligament made up of fine transparent fibers.
2. Accessories structures of the eye:
a. eyebrow
b. eyelid
c. lacrimal system
d. ocular muscles
e. ocular nerves
f. ocular blood vessels
Eye color is created by the amount and type of pigment in the iris.
Multiple genes inherited from each parent determine a person’s eye color.
What is the function of the Eye?
Function of the Eye:
Light comes in through the cornea.
The amount of light coming in is controlled by the pupil an opening that opens and closes.
The light focuses on the cones and rods of the retina a series of light-sensitive cells lining the back of the eye.
The retina acts like photoreceptor reacting to the incoming light and sending a record of it via the optic nerve to the brain.
