Lumbar Plexus

The Lumbar Plexus (pronounced: LUM-bar PLEK-sus) is a network of intersecting nerves in the lumbar region of the body, specifically in the posterior abdominal wall.

Etymology

The term "Lumbar" is derived from the Latin word "lumbus," meaning loin, and "Plexus" is from the Latin "plexus," meaning braid or network.

Anatomy

The Lumbar Plexus is formed by the anterior rami (divisions) of the first four lumbar nerves (L1 to L4), and from contributions of the subcostal nerve (T12), which is the last thoracic nerve.

Branches

The Lumbar Plexus gives rise to several important nerves in the lower body, including the iliohypogastric nerve, ilioinguinal nerve, genitofemoral nerve, lateral femoral cutaneous nerve, obturator nerve, and the femoral nerve.

Function

The Lumbar Plexus provides motor and sensory nerve supply to parts of the pelvis and lower limb.
