The scapulothoracic joint is not a true anatomical joint but a functional articulation between the scapula and the thoracic cage, playing a crucial role in shoulder movement and stability. It facilitates a wide range of shoulder motions by allowing the scapula to glide over the ribcage, contributing to the overall mobility and function of the shoulder girdle.

The scapula, or shoulder blade, is a flat, triangular bone located in the upper back that plays a crucial role in shoulder mobility and stability by connecting the humerus (upper arm bone) with the clavicle (collarbone). It serves as an attachment site for multiple muscles, facilitating a wide range of arm movements and contributing to the overall function of the shoulder girdle.

The thoracic cage, also known as the rib cage, is a bony structure that surrounds and protects the heart and lungs in the thoracic cavity. It consists of the sternum, ribs, and thoracic vertebrae, providing support and facilitating respiration through its flexible yet sturdy design.

Shoulder movement involves the complex interaction of muscles, tendons, and bones that allow for a wide range of motion, including flexion, extension, abduction, adduction, and rotation. Understanding shoulder movement is crucial for diagnosing and treating injuries, improving athletic performance, and enhancing daily functional activities.

Mobility refers to the ability of individuals, goods, or information to move freely and efficiently across different spaces or systems. It encompasses various dimensions including physical movement, social mobility, and technological connectivity, each playing a crucial role in shaping economic opportunities and societal structures.

The shoulder girdle, also known as the pectoral girdle, is a set of bones that connects the upper limb to the axial skeleton and facilitates a wide range of shoulder movements. It consists primarily of the clavicles and scapulae, providing attachment points for numerous muscles and ligaments that enable arm mobility and stability.
