Anatomy of Thoracodorsal Nerve or Middle Subscapular Nerve ; Overview, Origin, Course, Supply, Motor

The Thoracodorsal Nerve, also known as the Middle Subscapular Nerve, is a motor nerve that arises from the posterior cord of the brachial plexus. Here's a brief overview of its anatomy: Origin and Course Origin: Posterior cord of the brachial plexus. Roots: Spinal nerves C6, C7, and C8. Course: It originates near the apex of the axilla, between the superior and inferior subscapular nerves, and posterior to the subscapular artery. It descends along the posterior wall of the axilla, crosses the subscapular artery, and then travels with the thoracodorsal artery to pierce the latissimus dorsi muscle. Innervation Muscle: Latissimus dorsi. Function: Provides motor innervation to the latissimus dorsi muscle, which is responsible for movements such as adduction, extension, and medial rotation of the arm #ThoracodorsalNerve
