OVERVIEW OF EYE ANATOMY
ANATOMY OF EYEANATOMY OF EYE
PUPIL
Black looking aperture (black due to the absorbing pigment of the retina )Allows the light to enter to the eye
THE OUTERMOST LAYER OF THE EYE BALL
THE WHITE AND OPAQUE PART OF EYEBALL
SCLERA
IRIS COLORED, RING MEMBRANE GIVES COLOUR TO THE EYE CONTROLS THE SIZE OF THE PUPIL DEPENDING ON THE AMOUNT OF LIGHT ENTERING INTO THE EYE
THREE LAYERS OF EYE
EXTERNAL LAYER – SCLERA AND CORNEAINTERMEDIATE LAYER- ANTERIOR (IRIS AND CILIARY BODY ) AND POSTERIOR (CHOROID )
INTERNAL LAYER – RETINA ( THE SENSORY PART )
CORNEA At the front of eyeball , sclera continues
into cornea . Dome-shaped transparent part of eyeball
Rays of light from outside world passes through cornea before passing through the lens
CHOROIDMiddle layer of the eyeball.
located between sclera and retina .
Provides nutrients and oxygen to the outer surface of the retina.
ANTERIOR CHAMBER The space between cornea and lens
Filled with aqueous humor
VITREOUS CHAMBER
Largest chamber of the eye Between lens and retina Filled with the amorphous somewhat gelatinous material of the vitreous body
RETINA SENSORY PART OF EYE
OPTIC NERVE Second of several pairs of cranial nerves The job of this nerve is to transfer visual information from retina to visual centre of brain via electrical impulse
The optic nerve made up of ganglion cells or nerve cell
EXTRAOCULAR MUSCLES
