What is "scapula"?

The scapula, commonly known as the shoulder blade, is a flat, triangular bone that connects the upper arm bone (humerus) to the collarbone (clavicle). The scapula plays a crucial role in the movement and stability of the shoulder joint. It provides attachment points for various muscles involved in arm and shoulder movements, such as lifting, pushing, and pulling. The scapula's mobility and position allow for a wide range of shoulder motions, including rotation, abduction, and adduction. It also serves as a protective shield for the underlying structures, including the lungs and part of the ribcage. The scapula's presence and proper functioning are integral to the overall strength, stability, and functionality of the shoulder complex.

Example

The scapula has several important bony landmarks, including the acromion and the coracoid process, which serve as attachment points for muscles and ligaments.

An injury to the scapula, such as a fracture or dislocation, can result in significant pain and limited mobility of the shoulder.

The muscles surrounding the scapula, such as the rotator cuff muscles, help facilitate a wide range of shoulder movements, including lifting, rotating, and stabilizing the arm.
