Eye section

The eye is a complex organ of vision, consisting of various membranes and structures. Let's look at the main elements of the eye shape:

The sclera is the outer shell of the eyeball, preserving its shape and density. It is transparent only in the cornea area.

The choroid is the middle layer of the eyeball containing blood vessels. It provides nutrition to the internal structures of the eye.

The retina is the inner layer of the eyeball, which contains light-sensitive receptors - rods and cones. It is in the retina that the image is formed.

The macula is the area of ​​the retina in the center of the visual field with the highest concentration of cones and maximum visual acuity.

The vitreous is a transparent jelly-like mass that fills the posterior chamber of the eye. It maintains the shape of the eye.

Aqueous humor is a clear liquid that fills the anterior and posterior chambers of the eye and provides nutrition to its structures.

The iris is a colored ring of smooth muscle that regulates the diameter of the pupil, changing the amount of light entering the eye.

The lens is an elastic transparent body behind the iris that changes curvature to focus images on the retina.

The cornea is the transparent convex part of the sclera that allows light to enter the eye.

The conjunctiva is a thin transparent mucous membrane covering the sclera and the inner surface of the eyelids.

These are the main elements of the anatomical structure of the eye, visible on its section. Their complex interaction allows the eye to perform the function of vision.
