Artery: Supratrochlear artery
The ophthalmic artery and its branches. (Supratrochlear artery labeled at center top.)
The arteries of the face and scalp. (Frontal labeled at upper right, above eye.)
Latin	arteria supratrochlearis, arteria frontalis
Gray's	subject #146 570
Supplies	forehead: integument, muscles, and pericranium
Source	ophthalmic artery, scalp

The supratrochlear artery (or frontal artery), one of the terminal branches of the ophthalmic artery, branches off where the ophthalmic travels posterior to the trochlea.

[edit] Course

It leaves the orbit at its medial angle by piercing the orbital septum with the supratrochlear nerve, and, ascending on the forehead, supplies the integument, muscles, and pericranium, anastomosing with the supraorbital artery, and with the artery of the opposite side.
