The eyelids are made up of two parts: the frontal skin鈥搈uscle layer is the soft layer, and the back hard segment is the tarsoconjunctival layer. They can easily be separated with a knife when entering along the gray line at the lid margin (Fig. 5.1). The skin of the lids is ...

The oculomotor nerve provides innervation to the levator palpebrae superioris muscle that keeps the eyelids open, a function assisted somewhat by Muller�s muscle which is innervated by the sympathetic nervous system. Eyelid closure is achieved by contraction of the orbicularis oculi muscle, ...
The main function of the eyelid is to provide the eye with protection. The skin of the eyelids is loose and elastic, allowing for movement. There are several types of glands in the eyelids, including tarsal glands that produce a sebaceous secretion that results in an oily surface of the tea...
Structures that must be considered in a description of lid anatomy are [1] The skin and subcutaneous tissue: The outermost layer that provides protection and houses glands. The orbicularis oculi muscle (shown below): This sphincter-like muscle encircles the eyelids, enabling closure and contributin...
The article reports the results of the anatomic observations from dissec ring 30 upper eyelids and 8 eyebrows of adult cadavers.In the eyebrow region,the ante- rior and posterior sheaths of the galea inclose the muscle plane where the frontalis,or- bicularis and corrugator muscles are interdigit...
The eyelids are soft tissue structures that cover and protect the anterior surface of the eyeball. The anatomy of the eyelid may seem complex, but if we dissolve its multi-layered structure it is actually quite simple: Skin Subcutaneous tissue Muscle - orbital part of the orbicularis oculi mus...
Eyelids.Anteriorly, the eyes are protected by the eyelids, which meet at the medial andlateralcorners of the eye, themedialandlateral commissure (canthus), respectively. Eyelashes.Projecting from the border of each eyelid are the eyelashes. ...
The eyelashes (cilia) are attached to the free edges of the eyelids; they are short, thick, curved hairs, arranged in a double or triple row: those of the upper eyelid, more numerous and longer than those of the lower, curve upward; those of the lower eyelid curve downward, so that ...
