Rib Cage Anatomy

Manubrium: The superior part of the sternum, articulates with the clavicles and the first pair of ribs.
Sternal Angle: The junction between the manubrium and the sternal body, important anatomical landmark; corresponds to the second rib.
Sternal Body: The central portion of the sternum; articulates with ribs 2-7.
Jugular Notch: A visible dip in the top of the manubrium; easily palpable and signifies the boundary between the neck and chest.
Clavicular Notch: On the manubrium, where the clavicle articulates; provides support for shoulder attachment.
Xiphoid Process: The small, bony structure at the bottom of the sternum; varies in shape and size, often serves as a landmark for CPR.
Xiphisternal Joint: The fusion point between the xiphoid process and the sternal body; commonly used as a reference point in anatomy.
Clavical: Also known as the collarbone; connects the arm to the body and aids in stabilizing the shoulder.
True Ribs: Ribs 1-7 that attach directly to the sternum through their own costal cartilage, providing a rigid structure to the thoracic skeleton.
False Ribs: Ribs 8-12 that do not attach directly to the sternum; rely on indirect connections via the costal cartilage of rib 7.
Vertebrochondral Ribs: Another name for false ribs (8-10), featuring indirect connections to the sternum for flexibility.
Floating Ribs: Ribs 11-12 that do not connect to the sternum or any other ribs; provide additional mobility to the rib cage.
Scapula: Also known as the shoulder blade; a flat bone that connects the humerus to the clavicle.
Costal Cartilage: Connective tissue that links ribs to the sternum; allows for flexibility and expansion during respiration.
Humerus: The long bone of the upper arm; connects the shoulder to the elbow.
Structure of a Typical Rib: Composed of a head, neck, tubercle, and shaft; varies in curvature and length depending on its position in the cage.
