Origin
The communicating branch to iliohypogastric nerve originates from the subcostal nerve, just lateral to the spinal column.
Course
From its origin the communicating branch descends vertically and takes a short course, along the medial border of psoas major, to connect with the iliohypogastric nerve (Netter, 2011).
Branches
As this branch is a communicating branch, it does not give off any branches.
Supplied Structures
The communicating branch sends fibers to the iliohypogastric nerve. These supply sensory innervation to the skin over the hypogastric (pubic bone) region, upper thigh, and lateral gluteal region.
