Origin
The lateral and medial cutaneous branches arise from the dorsal branch of the subcostal artery.
Course
The lateral cutaneous branch follows the lateral branch of the posterior ramus of the corresponding thoracic nerve. It travels posteriorly, between the intertransverse ligaments and muscles and the vertebral body. It courses between the longissimus and iliocostalis muscles and piercing the latissimus dorsi to become superficial.
Branches
There are no named branches.
Supplied Structures
Along its course, the lateral cutaneous branch of the dorsal branch of the posterior intercostal artery supplies the longissimus thoracis, iliocostalis, and latissimus dorsi muscles, overlying fascia and skin.
