The eyelids are two movable vela, situate in front of the eye; which by their separation permit the organ to receive the impression of light, or by their greater or less occlusion protect it from the influence of too great light, or from the action of extraneous bodies. They are separated, above, from the forehead, by the eyebrows; and, below, are confounded with the cheeks. They are distinguished into upper, Palpebra major seu superior, Epicoe'lis- and lower, Palpebra minor seu inferior, Hypocoelis, Hypacoelum, Hypacylum. The former is much broader and more movable than the latter. They are separated by a transverse cleft- Fissura palpebrarum-and their edges are thick, and furnished with the cilia or eyelashes. Supported by the tarsal cartilages, they unite at the extremities of the transverse diameter of the orbit, forming two angles, the innermost being called the greater angle of the eye, or inner or greater conthus; the other, the lesser, or external angle or canthus. They are formed, 1. Of a thin dermoid texture: 2. Of a muscular membrane, - a portion of the orbicularis: 3. Of a particular fibrous membrane: 4. Of the tarsi: 5. Of a mucous membrane, - a part of the tunica conjunctiva. Their vessels and nerves are called Palpebral.
