Innervation – Nerve control
Femoral nerve, sometimes obturator nerve.
The pectineus muscle is considered a composite muscle as the innervation is by the femoral nerve (L2 and L3) and occasionally, in about 20% of the population, a branch of the obturator nerve called the accessory obturator nerve.
The obturator artery is a branch of the internal iliac artery that passes antero-inferiorly (forwards and downwards) on the lateral wall of the pelvis, to the upper part of the obturator foramen, and, escaping from the pelvic cavity through the obturator canal, it divides into both an anterior and a posterior branch.
