What is the Clavicle in Anatomy?
The clavicle, also known as the collarbone, is a long, slightly curved bone located at the base of your neck, one on each side. It acts as a crucial link, connecting your arm to your body.
- Connects Arm to Body: The primary function of the clavicle is to connect your arm to your torso, specifically bridging the gap between your sternum (breastbone) and your scapula (shoulder blade). This connection is vital for shoulder movement and stability. [Source: My.Clevelandclinic.org, TeachMeanatomy.info, Britannica.com]
- Supports Shoulder Blade: The clavicle helps maintain the proper position of your shoulder blade as you move your arm. [Source: My.Clevelandclinic.org]
- Unique Bone: The clavicle is unique because it's the only long bone in the body that lies horizontally. [Source: Physiopedia.com, Wikipedia.org]
- S-Shaped Bone: Its distinctive S-shape provides structural strength and flexibility. [Source: Kenhub.com]
- Ligament Connections: Ligaments attach the clavicle to the sternum and scapula, providing stability and facilitating a wide range of shoulder movements. [Source: My.Clevelandclinic.org, Pubmed.ncbi.nlm.nih.gov]
Clinical Significance
The clavicle's prominent location makes it susceptible to fractures, which are common injuries, particularly in contact sports. Treatment can range from conservative measures to surgical intervention depending on the severity of the fracture. [Source: OrthoInfo.org, AAFP.org]
Etymology
The term "clavicle" originates from the Latin word "clavicula," meaning "little key." [Source: My.Clevelandclinic.org]
