Origin
The anterior cutaneous branch of Iliohypogastric nerve originates from the anterior ramus of the first lumbar nerve. Often, it may receive a contribution from the twelfth thoracic nerve.
Course
The anterior cutaneous branch originates between the transversus abdominis and internal abdominal oblique muscles, on top of the iliac crest. It runs obliquely and medially to pierce the external abdominal oblique muscle, just medial to the anterior superior iliac spine.
Branches
There are no branches as it is a terminal nerve.
Supplied Structures
The anterior cutaneous branch of Iliohypogastric nerve receives sensory information to the skin of the hypogastric, hip, and upper thigh regions.
