What is the name of the structure that includes the clavicle, scapula, and humerus in the upper extremities?

The structure that includes the clavicle, scapula, and humerus in the upper extremities is known as the shoulder girdle. This anatomical region plays a crucial role in connecting the upper limb to the trunk of the body, allowing for a wide range of motion and mobility in the arm.

The clavicle, commonly referred to as the collarbone, serves as a strut that stabilizes the shoulder, while the scapula, or shoulder blade, provides attachment points for many muscles that facilitate arm movement. The humerus, which is the bone of the upper arm, connects at the shoulder joint with the scapula, forming a crucial articulation for numerous upper body movements.

The shoulder girdle is essential for both the stability and flexibility of arm movement, making it a vital area in functional anatomy. Understanding this structure is important for EMTs when assessing injuries and conditions related to the upper extremities.
