The eyebrow.

(pl. SUPERCILIA), In anat. the eyebrow; the projecting arch, covered with short hairs, above the eyelids: in anc. arch. the upper member of a cornice. It is also applied to the small fillets on each side of the scotia of the Ionic base.

Same etymon. The eyebrows (Sc.) Brees, (Prov.) Eye-breen, are two arched eminences, - convex above, and more or less prominent, according to the individual, - which lie on the superciliary arch of the os frontis, above the eyelids, and extend from the sides of the root of the nose to the temple. Their inner extremity or j head is more prominent than the outer or tail. The eyebrows are covered with short and stiff hairs, which are directed, obliquely, from within outwards, and are, commonly, of the colour of the hair. The skin in which these hairs are implanted, rests on the orbicularis palpebrarum, frontalis, and superciliaris muscles, which move the eyebrows in different directions. The eyebrows serve as an ornament to the countenance; and by covering the eye defend it from the impression of too strong a light. They direct the perspiration also from the eye.

L. for Eyebrow.

The eyebrow; an arched eminence of integument which surmounts the upper border of the orbit and supports numerous short, thick hairs, directed obliquely to the surface. It consists of thickened integument connected beneath with the orbicularis palpebrarum, corrugator supercilii, and occipitofrontalis.
