Subscapular Nerves The subscapular nerves are a group of nerves that arise from the posterior cord of the brachial plexus. They innervate specific muscles in the shoulder region. Here's an overview of the subscapular nerves: Types of Subscapular Nerves Upper Subscapular Nerve: Origin: Arises from the posterior cord of the brachial plexus, primarily from the C5 and C6 nerve roots. Innervation: Innervates the upper part of the subscapularis muscle. Function: Assists in the medial rotation of the arm at the shoulder joint. Lower Subscapular Nerve: Origin: Also arises from the posterior cord of the brachial plexus, primarily from the C5 and C6 nerve roots. Innervation: Innervates the lower part of the subscapularis muscle and the teres major muscle. Function: Assists in the medial rotation and adduction of the arm at the shoulder joint. Thoracodorsal Nerve (Middle Subscapular Nerve): Origin: Arises from the posterior cord of the brachial plexus, from the C6, C7, and C8 nerve roots. Innervation: Innervates the latissimus dorsi muscle. Function: Responsible for the extension, adduction, and medial rotation of the arm at the shoulder joint. Clinical Significance Injuries to Subscapular Nerves: Damage to these nerves can lead to weakness or paralysis of the muscles they innervate, affecting shoulder movement and stability. Surgical Considerations: Knowledge of the anatomy and course of these nerves is crucial during shoulder surgeries to prevent inadvertent damage. #subscapularnerve
