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

Supratrochlear (Frontal) vein visible through the forehead

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.
