Examples of manubrium in the following topics:

  • Thoracic Cage: Sternum

    • The manubrium is the most superior region of the sternum and articulates with the clavicles or collarbones and the first pair of ribs.
    • The manubrium is the thickest portion of the sternum as it carries the greatest physical load.
    • Located below the manubrium, the gladiolus is the longest portion of the sternum and articulates with the ribs, either directly or indirectly, through the costal cartilage
  • Clavicle

    • Medially the clavicle is quadrangular in shape and articulates with the manubrium of the sternum forming the sternoclavicular joint. 
  • Clavicle Fracture

    • The medial end connects with the manubrium of the sternum and gives attachments to the fibrous capsule of the sternoclavicular joint, articular disc, and interclavicular ligament.
  • Cartilaginous Joints: Synchodroses

    • The joint between the manubrium and the sternum is an example of a cartilaginous joint.
  • Structural Classification of Joints

    • Symphyses are found between the manubrium and sternum (manubriosternal joint), intervertebral discs, and the pubic symphysis.
  • Cartilaginous Joints: Symphyses

    • The more prominent symphyses are the pubic symphysis; the symphyses between the bones of the skull, most notably the mandible (symphysis menti); sacrococcygeal symphysis; the intervertebral disc between two vertebrae; and in the sternum, between the manubrium and body, and between the body and xiphoid process.
