    Sternum

    Manubrium – bone that is trapezoidal in shape, makes up the superior aspect of the sternum.

    Jugular notch – concave notches on either side of the superior aspect of the manubrium, for articulation with the clavicles.

    Corpus or body – flat, rectangular bone making up the major portion of the sternum. The lateral aspects contain the notches for the true ribs, called the costal notches.

    Xiphoid process – variably shaped bone found at the inferior aspect of the corpus. Process may fuse late in life to the corpus.

    Clavicle

    Sternal end – rounded end, articulates with manubrium.

    Acromial end – flat end, articulates with scapula.

    Conoid tuberosity – muscle attachment located on the inferior aspect of the shaft, pointing posteriorly.

    Ribs

    Head, Neck, Tubercle, Shaft, and Costal groove.

    Scapulae

    Ventral surface, Dorsal surface, Spine, Coracoid process, Acromion, Glenoid fossa, Axillary margin, Medial angle, and Vertebral margin.
