Hip extension is primarily mediated by which nerve root level through the Gluteus maximus?

Explanation:
Hip extension is performed mainly by the gluteus maximus, which is innervated by the inferior gluteal nerve from the sacral plexus. This nerve carries fibers from the L5 to S2 segments, with S1 being the most prominent contributor for hip extension. Clinically, weakness of hip extension points to involvement around the S1 level. The other options involve different regions: L4-L5 relate more to knee or ankle actions, C7-C8 are cervical and unrelated to hip muscles, and L2-L3 are more about hip flexion.
