Document Summary

Special senses: the eye/vision (reading material: chapter 18 pages 491-500) 70% of all the receptors in the body are in the eye. Adult eye is a slightly irregular sphere in shape with a diameter of 2 and 1/2 cm. Only the anterior 1/6th of the eye of the surface is visible and the rest of our eye is enclosed and protected. Determine the significance of the eyebroaws. eyelid (palpebrae): All eyes are protected anteriorly by the eyelids. The anatomical term for eyelids is the palpebral. Free margins of our eyelids are separated from each other when the eyes are open. palpebral fissure separation of the free margin. When our eyes are opened there is a prominent fissure. Eyes closed, there is no palperbral fissure. medial, lateral canthus. Even though the free margins are separated by this fissure, the two eyelids are connected through at the medial and lateral angles of the eye.
