CLAVICLE Meaning and
Definition
-
The clavicle is a bone that is an integral part of the skeletal system, specifically the axial skeleton. Also commonly referred to as the collarbone, it is a long, slender, curved bone situated horizontally above the first rib. The clavicle extends from the sternum, or breastbone, and runs outwardly to connect with the scapula, or shoulder blade, on each side, forming the shoulder girdle. It acts as a structural link between the trunk and the upper limb, providing stability and mobility to the shoulder joint.
The clavicle serves multiple crucial functions in the body. Firstly, it acts as a protective shield, safeguarding the underlying nerves and blood vessels located in the neck and chest regions. Secondly, it serves as an anchor point for several vital muscles necessary for arm movements, such as the pectoralis major, deltoid, and trapezius muscles. Additionally, the clavicle contributes to the overall strength and stability of the shoulder joint, aiding in the transmission of forces from the upper limb to the axial skeleton.
Injuries to the clavicle are not uncommon, often resulting from direct impacts or falls onto the shoulder. These injuries can range from fractures, which are frequently treated using immobilization methods or surgical intervention, to dislocations and separations. Due to its superficial location, the clavicle is readily palpable and visible, making it a clinically important landmark for medical professionals when assessing the shoulder and upper limb regions.
