Anterior branch of the obturator artery
Encyclopedia
The anterior branch of the obturator artery runs forward on the outer surface of the obturator membrane
and then curves downward along the anterior margin of the foramen.
It distributes branches to the Obturator externus, Pectineus, Adductores
, and Gracilis
, and anastomoses with the posterior branch
and with the medial femoral circumflex artery
.
