Eyelids skin folds around the eyes in vertebrate animals and man. Eyelids serve to protect the eyeball from external injury, to moisten it with lachrymal fluid, and to remove foreign bodies from the eye. The majority of animals have paired (upper and lower), movable eyelids. In a number of sharks, amphibians, reptiles, birds, and some mammals, there is also a third movable eyelid—the nictitating membrane. In most mammals the third eyelid lacks musculature and is therefore immovable; in primates and in man it is reduced and forms a semilunar fold in the inner corner of the eye. Eyelids in man consist of upper and lower movable skin folds that cover the eyeball when closed and circumscribe the eye aperture. The boundary of the upper lid is the recess between the orbit and the eyeball; the lower lid is separated from the cheek by a poorly defined furrow. The eyelids consist of skin, subcutaneous tissue, a muscle layer, a cartilaginous plate, and the conjunctiva. The skin of the eyelids is thin and turns into conjunctiva along the edges, where the eyelashes grow and the openings of the glands are located. The blood vessel network of the eyelids is well developed; sensory innervation is effected by branches of the trigeminal nerve; motor innervation is by the facial nerve. Of greatest anthropological interest is the upper lid, the skin of which can form various types of folds—superior (suprapalpebral), median (palpebral), and inferior (tarsal). The last type of fold is more developed in the outer part of the eye and is manifested more strongly with age. Also distinguished is the Mongolian fold (epicanthic), which partially covers the lacrimal caruncle and is usually a continuation of the palpebral fold. The epicanthic fold is especially widespread among representatives of the Mongoloid race (up to 60 percent or more, especially frequent in women and children); it is absent among Caucasoids and Negroids (except for Bushmen).

eyelidsA pair of movable folds of skin which act as protective coverings of the eye. The upper eyelid extends downward from the eyebrow and is the more moveable of the two. When the eye is open and looking straight ahead, it just covers the upper part of the cornea; when it is closed, it covers the whole cornea. The lower eyelid reaches just below the cornea when the eye is open and rises only slightly when it shuts. Each eyelid consists of the following layers, starting anteriorly: (1) skin, (2) a layer of subcutaneous connective tissue, (3) a layer of striated muscle fibres of the orbicularis muscle, (4) a layer of submuscular connective tissue, (5) a fibrous layer, including the tarsal plates, (6) a layer of smooth muscle, (7) the palpebral conjunctiva. Syn. blephara; lids; palpebrae. See ablephary; blepharitis; ciliosis; ectropion; entropion; epicanthus; lid eversion; eyelid lamella; lagophthalmos; palpebral ligament; myokymia; orbital septum; phthiriasis; Cogan's lid twitch sign; Collier's sign; Dalrymple's sign; inferior palpebral sulcus; superior palpebral sulcus; tarsorrhaphy; tarsus; xanthelasma.
eyelids lamella The eyelid is sometimes conceptualized as consisting of an anterior and a posterior lamella. The anterior lamella consists of the skin, the layer of subcutaneous connective tissue and the layer of striated muscle fibres of the orbicularis muscle. The posterior lamella consists of the tarsal plates, a layer of smooth muscle (Müller's palpebral muscle), and the palpebral conjunctiva.
eyelids retractor muscles The eyelid muscles that open the palpebral aperture. The upper eyelid is elevated by the levator palpebrae superioris muscle and the superior tarsal muscle (of Müller) and the lower eyelid is depressed by the inferior tarsal muscle (of Müller).Patient discussion about eyelidsQ. eyelids what causes your eye lids too twitch? my left eye lid has been twitching on and off for about a week what causes it and how can i get it to stop.A. Not an answer, just another question - how long can this go on? My eyelid has been twitching, (likely lack of sleep) for almost a month now. Any treatment that I should seek?
