The glabella, in humans, is the area of skin between the eyebrows and above the nose. The term also refers to the underlying bone that is slightly depressed, and joins the two brow ridges. It is a cephalometric landmark that is just superior to the nasion. [1]
The skin thus drawn upon is thrown into folds, especially radiating from the lateral angle of the eyelids; these folds become permanent in senescence, and form the so-called "crow's feet". The Levator palpebræ superioris is the direct antagonist of this muscle; it raises the upper eyelid and exposes the front of the bulb of the eye. In ...
Few printed anatomies include it (Netter, et al.) and many authorities consider it to be part of the orbicularis oculi muscle. [ 1 ] On the other hand, many dermatologists , ophthalmologists , and plastic surgeons [ 2 ] hold that the depressor supercilii is a distinct muscle and has a definite, individual effect on the movement of the eyebrow ...
An eyelid is a thin fold of skin that covers and protects the eye. The levator palpebrae superioris muscle helps in the movement of eyelid. The human eyelid features a row of eyelashes along the eyelid margin, which helps in protection of the eye from dust and foreign debris. The main function of eyelid is to keep the cornea moist and clean.
fascia over lower part of nasal bone: skin of lower part of forehead between eyebrows: facial artery: facial nerve [CNVII], buccal branch: draws down medial angle of eyebrow (giving expressions of frowning) 2 1 depressor septi nasi: head, nose (left/right) incisive fossa of maxilla: nasal septum and back part of alar part of nasalis: superior ...
The brow ridge is a nodule or crest of bone situated on the frontal bone of the skull. It forms the separation between the forehead portion itself (the squama frontalis) and the roof of the eye sockets (the pars orbitalis). Normally, in humans, the ridges arch over each eye, offering mechanical protection.
In certain instances, excessive lower lid laxity creates the Fornix of Reiss – a pocket between the lower eyelid and globe – which is the ideal location to administer topical ophthalmic medications. Eyelid edema is a condition in which the eyelids are swollen and tissues contain excess fluid. It may affect eye function when it increases the ...
An eyebrow is an area of short hairs above each eye that follows the shape of the lower margin of the brow ridges of some mammals. In humans , eyebrows serve two main functions: first, communication through facial expression , and second, prevention of sweat, water, and other debris from falling down into the eye socket.
