The subscapular nerves are two distinct nerves, an upper and a lower, that innervate the subscapularis muscle. These nerves originate from the brachial plexus.
Details of the Subscapular Nerves
Here's a breakdown of the subscapular nerves:
- Origin: The brachial plexus.
- Types:
- Upper subscapular nerve.
- Lower subscapular nerve.
- Target Muscle: Subscapularis.
- Path: They cross the axillary vein dorsally to reach the subscapularis muscle.
In essence, the upper and lower subscapular nerves work together to control the subscapularis muscle, which is important for shoulder movement and stability.
