The anterior cutaneous branch arises as the terminal branch of the eleventh intercostal nerve.
Course
As the terminal portion of the eleventh intercostal nerve pierces through the anterior rectus sheath, it becomes the anterior cutaneous branch.
Branches
The anterior cutaneous branches divide into medial and lateral branches that extend over the rectus sheath.
Supplied Structures & Function
The anterior cutaneous branch conveys sensory information from the skin of the anterior abdominal wall, just below the umbilicus. See our dermatome map for cutaneous innervation.
