Above, it articulates with the lower end of the body, and on the front of each superior angle presents a facet for part of the cartilage of the seventh rib; below, by its pointed extremity, it gives attachment to the linea alba. The sternum or breastbone is a flat bone located at the anterior aspect of the thorax. These fossae articulate with the medial ends of the clavicles, forming the sternoclavicular joints. It also provides a graphic of the regional lymph nodes of the thorax. The angle of Louis is the articulation formed by the fusion of the manubrium and the body.

Ribs 8—10 have their costal cartilages attached to the cartilage of the next higher rib. —The superior border is oval and articulates with the manubrium, the junction of the two forming the sternal angle angulus Ludovici. The xiphoid process varies much in form; it may be broad and thin, pointed, bifid, perforated, curved, or deflected considerably to one or other side. The inferior angle has a small facet, which, with a corresponding one on the xiphoid process, forms a notch for the cartilage of the seventh rib. You've got articulations with the clavicle and with the first costal cartilage here.
