Iliohypogastric
Iliohypogastric Nerve
The Iliohypogastric Nerve (pronunciation: il-ee-oh-hy-po-gas-trik) is a branch of the Lumbar Plexus that originates from the first lumbar nerve (L1).
Etymology
The term "Iliohypogastric" is derived from the Greek words "ilio" meaning flank, "hypo" meaning under, and "gastric" meaning stomach. Thus, the term refers to the nerve that runs under the stomach region and towards the flank.
Anatomy
The Iliohypogastric Nerve provides sensory innervation to the skin over the lateral and anterior parts of the Gluteal Region and the Hypogastric Region. It also provides motor innervation to the Internal Oblique Muscle and the Transversus Abdominis Muscle.
Clinical Significance
Damage to the Iliohypogastric Nerve can result in loss of sensation in the areas it innervates and weakness in the abdominal muscles. This can occur due to abdominal surgeries, hernia repairs, or trauma.
