Cartilage and Bone

There are three types of cartilage on the bases of characteristics of their extracellular matrix:

There are two distinct structural arrangement of bone tissue:

Osteons are arranged along the axis parallel to the long axis of the bone (Haversian canals run parallel to the long axis of the bone). Collagen in concentric lamellae are laid parallel to one another in any given lamella. Between adjacent lamellae the fibers are arranged in different directions. This arrangement provides strength to the osteons.
