Which of the following is wrong about eyes?
1. An adult human eye ball is nearly a spherical structure
2. Our paired eyes are located in sockets of the skull called orbits
3. The wall of the eye ball is composed of three layers
4. The external layer is composed of loose connective tissue and is called sclera

(1) Anterior portion of choroid

(2) Anterior portion of sclera

(3) Posterior portion of sclera

(4) Anterior portion of retina

(1) Ciliary bodies form it

(2) Pigmented and transparent

(3) Visible colored part of the eye

(4) Present in anterior part of eye

(1) Transparent

(2) Crystalline

(3) Held in place by tendons attached to the ciliary body

(4) Both A and C

(1) In front of the lens

(2) The aperture surrounded by the Iris

(3) Diameter of the pupil is regulated by collagen fibres of Iris

(4) All of these

(1) Innermost layer of eye

(2) Three layers of neural cells

(3) Ganglion is outermost cell

(4) Rods and Cones are the photoreceptors over there

(1) Red

(2) Green

(3) Blue

(4) Yellow

(1) When rodes are stimulated more than cones

(2) When cones are equally stimulated

(3) When rodes are equally stimulated

(4) When cones are stimulated more than rodes

(1) A point left to and slightly down the posterior pole of the eyeball

(2) A point medial to and slightly above the posterior pole of eye ball

(3) A point right to and slightly above the posterior pole of eyeball

(4) A point medial to and slightly down the posterior pole of the eyeball

(1) Photoreceptor cells are not present in blind spot

(2) Retinal blood vessels enter at that point

(3) Optic nerves leave the eye at this point

(4) Is slightly below the posterior pole of the eyeball.
