| Anatomical terminology | |
Thesupratrochlear artery (orfrontal artery) is one of the terminal branches of theophthalmic artery. It arises within theorbit.[1][2] It exits the orbit alongside thesupratrochlear nerve. It contributes arterial supply to the skin, muscles and pericranium of the forehead.[3]
It branches from the ophthalmic artery near thetrochlea of thesuperior oblique muscle in theorbit.[1][2]
The supratrochlear artery branches from the ophthalmic artery in theorbit near thetrochlea of thesuperior oblique muscle.[1][2]
After branching from the ophthalmic artery, it passes anteriorly through the superomedial orbit. It travels medial to thetrochlear nerve. With thesupratrochlear nerve, the supratrochlear artery exits the orbit through the supratrochlear notch (variably present), medial to thesupraorbital foramen. It then ascends on the forehead.[citation needed]
The supratrochlear artery anastomoses with the contralateral supratrochlear artery, and the ipsilateralsupraorbital artery.[3]
The supratrochlear artery supplies blood to the skin of the medial aspect of the forehead and scalp, as well as the underlyingpericranium andfrontalis muscle.[citation needed]
