The supratrochlear artery (or frontal artery) is one of the terminal branches of the ophthalmic artery. It arises within the orbit. [1] [2] It exits the orbit alongside the supratrochlear nerve. It contributes arterial supply to the skin, muscles and pericranium of the forehead. [3]
The ophthalmic artery (OA) is an artery of the head. It is the first branch of the internal carotid artery distal to the carotid sinus . Branches of the ophthalmic artery supply all the structures in the orbit around the eye , as well as some structures in the nose , face , and meninges .
the supratrochlear artery to the midline forehead. The supratrochlear artery is a branch of the ophthalmic branch of the internal carotid artery. the supraorbital artery to the lateral forehead and scalp as far up as the vertex. The supraorbital artery is a branch of the ophthalmic branch of the internal carotid artery. external carotid
The supratrochlear nerve passes medially [3] above the trochlea of the superior oblique muscle. [2] [3] It then travels anteriorly above the levator palpebrae superioris muscle. [1] It exits the orbit through the supratrochlear notch or foramen. [3] It then ascends onto the forehead beneath the corrugator supercilii muscle and frontalis muscle ...
The perfusion of the paramedian forehead flap comes from three sources: randomly, through the frontalis muscle and through the supratrochlear artery. [1] Because the forehead flap is an axial flap with a pedicle containing its dominant vessel, the pedicle can safely be narrowed to 1 to 1.2 cm. [1]
In anatomy, arterial tree is used to refer to all arteries and/or the branching pattern of the arteries. ... Supratrochlear artery; Dorsal nasal artery.
The short posterior ciliary arteries contribute arterial supply to the choroid, ciliary processes, [3] optic disc, the outer retina, and Bruch's membrane. [1]Some branches of the short posterior ciliary arteries supply the optic disc by means of an anastomotic ring - the circle of Zinn-Haller or circle of Zinn - which is associated with the fibrous extension of the ocular tendons (common ...
It is supplied by the supraorbital artery, the supratrochlear artery, and the occipital artery. It is innervated by the facial nerve. The epicranium also includes the skin of the scalp and the layer of subcutaneous tissue below it.
