What is the main function of the scapula?
The scapula, also known as the shoulder blade, is a flat, triangular bone located on the back of the rib cage. It forms the posterior part of the shoulder joint and provides a stable platform for the attachment of muscles that control movement of the arm.
The main function of the scapula is to provide a stable base for the attachment of muscles that control movement of the arm. These muscles include the trapezius, rhomboids, levator scapulae, and serratus anterior. The trapezius is responsible for elevating and rotating the scapula, the rhomboids retract the scapula, the levator scapulae elevates the scapula, and the serratus anterior protracts the scapula.
The scapula also provides a surface for the attachment of the clavicle and humerus. The clavicle is a long bone that connects the scapula to the sternum, and the humerus is the long bone of the upper arm. The scapula allows for a wide range of movement of the arm, including flexion, extension, abduction, adduction, and rotation.
In summary, the main function of the scapula is to provide a stable base for the attachment of muscles that control movement of the arm. It also provides a surface for the attachment of the clavicle and humerus, and allows for a wide range of movement of the arm.
