AQUEOUS HUMOUR - watery liquid; nourishes the cornea, maintains the shape of the front of eye
BLIND SPOT - where the optic nerve leaves the eye; contains neither rods nor cones
CHOROID - absorbs light, prevents internal refraction, contains blood vessels
CILIARY MUSCLES - ring of muscles; changes the shape of the lens
CONJUNCTIVA - delicate mucous membrane, attached to the cornea; covers the front part of the eye
CORNEA - transparent outer layer; allows light through, refracts light rays
FOVEA - shallow pit on the retina, contains no blood vessels; contains cones, responsible for sharp vision
IRIS - pigmented part of the eye; contracts/relaxes the circular and radial muscles to change pupil size
LENS - transparent; changes shape to focus image on retina
OPTIC NERVE - carries nerve impulses from the retina to the brain
PUPIL - hole in the choroid, appears as a black dot in the iris; determines the amount of light entering the eye
RETINA - light sensitive membrane; contains rods and cones, receives image from the lens
SCLERA - tough outer layer; offers protection from mechanical injury, provides area for muscle attachment
VITREOUS HUMOUR - jelly-like fluid, transparent; supports the lens, helps to maintain the shape of the eye
The seven main parts of the eye are the sclera, pupil, lens, cornea, optic nerve, retina and iris.
what are the vital parts of the human eye
I
the eye ball and the eye .x
The parts of the human eye are:1. Iris2. Pupil3. Cornea4. Sclera5. Lens6. Macula7. Retina8. Optic Nerve
yes the human eye
I added a link below that has a very cool diagram of the eye.
mouth(:
more than 2 million working parts
You use a foam ball and you paint all the parts of the eye on the model.
The whole thing. The Lens
Ear, leg, eye, arm.
The optic disc in the human eye is the part of the eye that is connected to the retina and carries visual information to the thalamus and other parts of the brain.
welll it is the lower cornea
