The lumbar plexus and its branches. (Iliohypogastric visible at upper left.)
|Innervates||Sensory: Skin over the lateral gluteal region and above the pubis
Motor: internal and transverse abdominal muscles
|Anatomical terms of neuroanatomy|
The iliohypogastric nerve is the superior branch of the anterior ramus of spinal nerve L1 (one of the lumbar nerves) after this nerve receives fibers from T12 (subcostal nerve). The inferior branch is the ilioinguinal nerve.
It then perforates the posterior part of the transversus abdominis, near the crest of the ilium, and divides between that muscle and the obliquus internus abdominis into a lateral and an anterior cutaneous branch.
