COLLAR BONES Meaning and
Definition
-
Collar bones, also known as clavicles, are key bones located in the human body that serve as part of the skeletal system. They are long and slender bones situated horizontally on each side of the upper chest, connecting the sternum (breastbone) to the scapulae (shoulder blades).
The collar bones play a crucial role in providing structural support to the upper body, particularly the shoulder girdle. They act as a bridge between the sternum and the shoulders, aiding in the movement and stability of the shoulders. Additionally, collar bones help to maintain the proper alignment of the arms, helping to distribute weight evenly between the upper limbs and chest.
These bones are easily palpable on most individuals, forming a subtle ridge or protrusion along the upper aspect of the chest when touched. They are relatively delicate compared to other bones and can be susceptible to fractures, especially when subjected to significant trauma or impact.
The collar bones are essential in protecting vital structures such as blood vessels and nerves that pass beneath them. They also contribute to the overall aesthetics of the upper body, providing a distinct shape and definition to the region between the neck and shoulders.
In summary, collar bones are paired, slender bones located horizontally on each side of the upper chest, playing a crucial role in supporting the shoulder girdle, maintaining proper alignment and movement of the arms, and protecting vital structures.
Etymology of COLLAR BONES
The word "collarbone" is derived from the Old English word "colerban" or "collarban", which was a combination of "collar" (meaning neck) and "ban" (meaning bone). The term was used to describe the bone located between the neck and the shoulders, which resembles a collar that goes around the neck. Over time, the word "collarbone" replaced the Old English term and has been commonly used to refer to the clavicle, the long bone that connects the shoulder blades to the breastbone.
