The substance and epiphysis of the ribs

All the ribs have it in common that they are made up of a bony (from a through f to A in fig. 3) and cartilaginous (from B to E in the same fig., or A, B in fig. 1) substance, and that they possess an epiphysis (L and M in fig. 4; figs. 4 and 5 show a rib broken at F) at the spot where they are joined to the bodies of the vertebrae and where you will hear they swell out into capitula [facies articulares superior et inferior capitis costae].
