Long Thoracic and Thoracodorsal Nerves

  • Amgad S. Hanna


The long thoracic nerve arises from the posterior aspect of C5, C6, and often C7 ventral rami. It travels within the scalenus medius muscle. It then runs over the lateral surface of the serratus anterior supplying it with multiple branches. The thoracodorsal nerve (C6, C7, and C8) arises from the posterior cord. It courses anterior to the latissimus dorsi muscle along with the corresponding vessels and supplies the muscle.
