=Costae=
*Arranged in pairs and articulate with two successive vertebrae
*Bony dorsal part, body of rib, and ventral costal cartilage
*Increase in length, curvature and amount of cartilage craniocaudally
*Cartilage of last rib may fail to join that of its neighbor: said to be '''floating'''
*Join ventrally on the midline at the '''Sternum''', which is comprised of three parts
**Manubrium: most cranial, projects beyond the first set of ribs and can be palpated
**Body: segmented '''sternebrae''' joined by cartilage in young animals that is later replaced by bone
**'''Xiphoid Cartilage''': caudal end that projects between lower ends of costal arches, providing attachment for the '''linea alba'''
