which is the coloured part of the eye. The iris regulates the size of the pupil. The choroid is the vascular layer of the eye that lies between the retina and the sclera. The choroid is thickest in the back of the eye at about 0.2 mm and narrows to 0.1 mm in the peripheral part of the eye. It contains
the retinal pigmented epithelial cells and provides oxygen and nourishment to the outer retina.

34) D. Occipital lobe

35) A. The eye lens is made of tranparent proteins called crystallins. The proteins are arranged in approximately 20,000 thin concentric layers. The average concentration of lens is about twice than
that of other intracellular proteins & is throught to play a structural role in the lens.

36) D. Iris muscles

37) D. Retina

38) B. Aqueous chamber

39) A. Glucoma develops due to increased intraocular tension as a result of blocking of canal of schlemm. The pressure in eye rises above the normal range of 15-20 mm of Hg since to aqueous humour is not drained out into the blood.

40) D. Choroid in the middle layer of the eye which is highly vascular and covered with pigment cells.

41) D. Aqueous humour

42) B. Opsin and Retinal

43) B. Equilibrium

44) D. Semicircular canal

45) D. In glaucoma, there is over production of vitreous humour which increases the pressure in the eye and this crushes the delicate cells of the retina, causing blindness.
