Shoulder Tenderloin

The notch of the scapula, also known as the incisura scapulae, is an important anatomical element of the shoulder girdle. It is located on the upper edge of the blade and is formed by its outer edge.

The scapular notch has several names, including PNA (posterior notch of the scapula), BNA (bony notch of the scapula), and JNA (jugal notch of the scapula). Despite their different names, they all refer to the same anatomical element.

Important structures such as nerves and blood vessels are located near the notch of the scapula. In particular, the scapular artery and nerves responsible for the innervation of the shoulder muscles pass here. In addition, the notch of the scapula is the attachment point for some muscles of the shoulder girdle.

The notch of the scapula plays an important role in the movement of the arm and shoulder. It allows the scapula to move up and down freely with the arm, allowing for a wider range of motion. In addition, notching the scapula helps reduce the load on the shoulder joint by distributing it over the entire surface of the scapula.

Despite its importance, scapular notching can be a source of pain and discomfort in some conditions. For example, some people may have scapular notch syndrome, which causes pain in the notch area. Also, the notch of the scapula can be damaged due to injuries to the shoulder girdle.

Overall, the notch of the scapula is an important element of the anatomy of the shoulder girdle, allowing free movement of the arm and shoulder. Its location and function are important for maintaining the health and mobility of the shoulder girdle.
