2023年11月2日 · Being a mixed nerve, the iliohypogastric nerve supplies both motor and sensory innervation to the abdominal muscles, as well as sensory innervation to the skin of the posterolateral gluteal and suprapubic regions.

The iliohypogastric nerve is a nerve that originates from the lumbar plexus that supplies sensation to skin over the lateral gluteal and hypogastric regions and motor to the internal oblique muscles and transverse abdominal muscles.

The iliohypogastric nerve is a mixed nerve which arises from the anterior branch(es) of the L1 nerve and frequently the T12 nerve. It emerges along the lateral margin of the psoas muscle to pass anterior to the quadratus lumborum.

2023年1月1日 · Along its course, the iliohypogastric nerve innervates the skin over the buttocks, ileum, and skin overlying the inferior portion of the rectus abdominis muscle. It also sends motor branches to the inferior portions of the transversus abdominis, external oblique, and internal oblique muscles.

2024年8月5日 · The iliohypogastric nerve is the first major branch of the lumbar plexus. It runs to the iliac crest, across the quadratus lumborum muscle of the posterior abdominal wall. It then perforates the transversus abdominis, and divides into its terminal branches.

2024年3月19日 · The iliohypogastric nerve arises from the anterior ramus of the L1 nerve root of the lumbar plexus along with the ilioinguinal nerve. It is a sensory nerve that provides lateral and anterior cutaneous branches supplying the posterolateral gluteal skin and skin in the pubic region.

The iliohypogastric nerve supplies sensory innervation to the skin over the hypogastric (pubic bone) region, upper thigh, and lateral gluteal region.

2025年1月20日 · Abdominal Wall Muscles: One of the main functions of the iliohypogastric nerve is to provide motor innervation to the internal oblique and transversus abdominis muscles. These muscles play crucial roles in supporting the abdominal contents …

Motor innervation is provided to the transversus abdominis muscle and the internal oblique muscle. Sensory innervation is supplied to some of the abdominal muscles, the suprapubic and...

In parallel to the ilioinguinal nerve, the iliohypogastric nerve emerges from the lateral border of the psoas muscle, anterior to quadratus lumborum muscle, behind the renal fossa, into the kidney fat, and behind the lower pole of the kidney.
