The origin of the subscapularis is predictable and arises from the anterior portion of the scapula called the subscapularis fossa. 151112 The muscle occupies almost the entire fossa making it the largest muscle attached to the scapula. The insertion of the subscapularis.
Twenty cadaveric shoulders were dissected and the subscapular nerves were identified from the posterior cord of the brachial plexus to the muscle insertion. The nerve length from the origin to the muscle insertion and the distance to the myotendinous junction were measured in various shoulder positions including neutral external and internal rotation.

Trigger Point Activating subscapularis Trigger Point Activating A persistent medially rotated humerus in tandem with an abducted Scapula immobilized which is observed with individuals that sleep on their shoulder or who sit in a chair applying pressure to the shoulder blade with their head dropped may activate TrPs in the Subscapularis.
The remaining three are the supraspinatus infraspinatus and subscapularis. The teres minor originates at the lateral border of the scapula and inserts at the inferior facet of greater tubercle of the humerus. The primary action of the teres minor is lateralexternal rotation of arm and stabilisation of the humerus.
