Lumbar Plexus

Lumbar Plexus is a network of intersecting nerves in the lumbar region of the human body. The unification of ventral rami of L1 to L3 lumbar nerves and big upper part of ventral ramus of L4 nerve inside the substance of psoas major makes lumbar plexus. The

Genitofemoral Nerve

Genitofemoral nerve originates from the LI and L2 ventral rami, the genitofemoral nerve is formed within the matter of psoas major. Opposite the third or fourth lumbar vertebra, genitofemoral nerve goes down obliquely via the muscle to emerge on its medial border. It then goes down below

Iliohypogastric Nerve

The iliohypogastric nerve is the first significant branch of the lumbar plexus. Iliohypogastric nerve is a sensory nerve which supplies lateral and anterior cutaneous branches supplying the posterolateral gluteal skin as well as skin in the pubic region. Origin The iliohypogastric nerve generally emerges from the ventral

Ilioinguinal Nerve

The ilioinguinal nerve is a division of the LI nerve root with a support via T12 in some patients. The nerve goes with a curvilinear course that takes ilioinguinal nerve via its genesis of the LI and sometimes T12 somatic nerves to within the concavity of the

Inferior Gluteal Nerve

The inferior gluteal nerve is created from the posterior divisions of the L5, S1 and S2 nerve roots of the sacral plexus. The nerve is the primary motor nerve that provides the gluteus maximus muscle. Inferior gluteal is responsible for the motion of the gluteus maximus in
