What is the significance of the clavicle?

The clavicle, commonly known as the collarbone, serves several important functions, and its significance as a landmark for physicians is particularly noteworthy. It is a palpable and easily identifiable structure that divides the neck from the thorax, marking the border between these two anatomical regions. This distinction is crucial for medical professionals during examinations and procedures, as it helps in locating other anatomical structures and in assessing conditions related to the shoulder, chest, and neck.

In addition to its role as a landmark, the clavicle provides attachment for muscles and supports the shoulder girdle. While it does play a role in protecting certain thoracic structures and assisting in the movement of the arm, its primary significance in a clinical context is that it provides a reference point for physicians, facilitating accurate assessments and interventions.
