Document Summary
Lecture 17: organs of special sense the eye. The layers and the lens serve as boundaries for 3 chambers: anterior chamber between cornea and iris, posterior chamber between iris and lens. These chambers contain a watery substance called aqueous humor: vitreous chamber between lens and retina. This chamber contains a gel substance called vitreous humor. Sclera consist of 3 layers of dense fibrous connective tissue: corneosclera limbus transition between cornea and sclera, functions. Loose connective tissue and fenestrated capillaries: provides nutrients to retina, lamina vitrea (cid:894)lv(cid:895) (cid:894)bru(cid:272)h"s (cid:373)e(cid:373)(cid:271)ra(cid:374)e(cid:895) Thin layer between capillaries and pigment epithelium of the retina: function transport nutrients to retina and metabolic waste away from retina. Iris forms a contractile diaphragm in front of the lens: composed of, vascularized connective tissue stroma with melanocytes. Smooth muscles the constrictor (sphincter) and dilator pupillae muscles for adaptation to ambient light: pigment epithelium. Eye colour without stroma pigments is blue due to the pigment epithelium.
