Quick Summary

The obturator nerve is a major nerve that originates from the lumbar plexus, formed by spinal nerves L1–L4. This nerve travels through the thigh via the obturator foramen and innervates muscles in the medial thigh, including the adductor muscles. These muscles are responsible for drawing the thigh inward toward the body's midline. The obturator nerve also provides sensory information to the knee joint's articular capsule.12
