Clavicle Bone – An Introduction

  • The clavicle or collarbone (os clavicula) is located superior to the first rib and runs horizontally from the manubrium of the sternum to the acromion of the scapula.
  • A superior view of the clavicle shows it is shaped somewhat like an “S”. The medial end curves anteriorly and the lateral end curves posteriorly.
  • Along with the scapula, the clavicle forms the shoulder or pectoral girdle, which connects the humerus (arm) to the axial skeleton.
  • The clavicle functions like a strut or lever arm to help support (suspend) the humerus and scapula and maintain their position relative to the rib cage.
