õlavööt

The õlavööt, commonly known as the shoulder girdle or pectoral girdle, is a complex of bones and muscles that connects the upper limbs to the axial skeleton. In humans, it consists of the clavicle (collarbone) and the scapula (shoulder blade). These bones articulate with each other and with the sternum (breastbone) to form the shoulder joint. The primary function of the shoulder girdle is to provide a base for the movement of the arms, allowing for a wide range of motion. It also plays a role in supporting the weight of the upper body and transmitting forces from the upper limbs to the trunk. The muscles attached to the shoulder girdle, such as the deltoid, rotator cuff muscles, and trapezius, are crucial for stabilizing the shoulder joint and performing various arm movements like lifting, rotating, and reaching. Disruptions to the õlavööt, whether through injury or congenital conditions, can significantly impact mobility and function.
