Manubrium of sternum

Sternum, superior most segment that has a suprasternal notch with a clavier notch on either side, articulates with clavicle so pectoral girdle; first rib cartilages attach just below clavicular notches

Xiphoid process of sternum

Inferior segment; protrusion that provides an attachment site for certain abdominal muscles

Body sternum

Large middle segment; features sternal angle where manubrium and body meet and second rib cartilage attaches; lateral edge of remaining body has notches for third through seventh rib cartilages
