Text Appearing Before Image:
The Obturator Nerve supplies the Obturator externus and Adductor musclesof the thigh, the articulations of the hip and knee, and occasionally the integumentof the thigh and leg. It arises by two branches: one from the third, the otherfrom the fourth lumbar nerve, receiving also some fibres from the second. Itdescends through the inner fibres of the Psoas muscle, and emerges from its innerborder near the brim of the pelvis; it then runs along the lateral wall of the pelvis,above the obturator vessels, to the upper part of the obturator foramen, where itenters the thigh, and divides into an anterior and a posterior branch separated bythe Adductor brevis muscle. The anterior branch (Fig. 511) passes down in front of the Adductor brevis,being covered by the Pectineus and Adductor longus, and at the lower border of LUMBAR PLEXUS. Ill Fig. 510. Fig. 511.

Nerves of the Lower Extremity, front view. 772 THE SPINAL NERVES. the latter muscle communicates with the internal cutaneous and internal saphenousnerves, forming a kind of plexus. It then descends upon the femoral artery, uponwhich it is finally distributed. This nerve near the obturator foramen gives off an articular branch to the hip-joint. Behind the Pectineus it distributes muscular branches to the Adductorlono-us and Gracilis, and occasionally to the Adductor brevis and Pectineus, andreceives a communicating branch from the accessory obturator nerve.
