Where does the teres minor muscle originate?

The teres minor muscle originates from the lateral border of the scapula, which plays a crucial role in the stability and movement of the shoulder joint. This location allows the teres minor to participate in shoulder adduction and external rotation, making it important for various upper body movements.

In anatomy, understanding the origin of muscles is essential, as it determines the muscle’s actions and how it can affect surrounding structures. By originating from the lateral border of the scapula, the teres minor is positioned to work closely with the rotator cuff muscles, helping to stabilize the shoulder during activities that require strength and mobility.

This specific origin location is key to recognizing the anatomical relationships within the shoulder area and understanding how injuries to this region can impact the function of the teres minor and associated muscles.
