Which nerve shares a cutaneous area with the obturator nerve?

The obturator nerve primarily innervates the medial thigh, providing sensation to the skin in this area. One of the nerves that shares a cutaneous area with the obturator nerve is the L2 nerve. The L2 segment contributes to the sensory innervation of the medial thigh and groin, overlapping with the distribution of the obturator nerve.

This overlap occurs as the L2 nerve supplies the area that is adjacent to the territory of the obturator, particularly in the vicinity of the groin. It is important to understand that sensory fields can often overlap between different nerves, reflecting the complexity of nerve distributions in the body. This anatomical relationship highlights how different segments of the lumbar plexus interact and share functions in the innervation of the thigh region.
