Sense organ HUMAN EYE

Описание: ur topic for today is Human Eye.
The human eye is one of the most valuable sense organs that enables us to see the world around us.
Let us study about the different parts of an eye.
Sclera is a tough outer coat that protects the entire eyeball.
Cornea is the front portion of the eye.
It is convex in shape and bulges outside.
Light enters the eye through the cornea.
Iris is a dark muscular diaphragm located just behind the cornea.
It regulates the amount of light entering the eye by adjusting the size of the pupil.
Pupil is a hole in the middle of the iris.
Size of the pupil decreases or increases depending upon the intensity of light entering the eye.
Retina is a delicate membrane having a large number of light sensitive cells.
An inverted real image of the object is formed on the retina.
The electrical signals generated by the cells are sent to the brain through the optic nerve.
The brain reassembles the signals into a meaningful image and gives rise to the sensation of vision.
