The clavicle is another name for the collarbone. It's also sometimes called the keybone.
Understanding the Collarbone
The collarbone, or clavicle, is a crucial bone in the human body. As the reference states, it's a slender, S-shaped bone, roughly 6 inches (15 cm) long. Its primary function is to act as a strut, connecting the shoulder blade (scapula) to the sternum (breastbone). This connection is vital for shoulder movement and stability.
Key Features and Functions:
- Shape: Its distinctive S-shape is important for its structural role.
- Location: It sits horizontally across the upper chest, just above the first rib.
- Function: It provides structural support to the shoulder, allowing for a wide range of motion while also protecting underlying blood vessels and nerves.
This simple bone plays a vital role in upper body mobility and stability. Understanding its other names – clavicle and keybone – provides a more complete anatomical picture.
