Dissection of male pelvis from a lateral approach
Piriformis muscle and nerve supply, medial view
The right sacral plexus has been resected to permit a view of the piriformis muscle. The nerves to this muscle (19), derived from the first and second sacral nerves and given off from the adjacent part of the sacral plexus, have been preserved.
