Chapter 5 - Cartilage and Bone
Cartilage and bone are connective tissue specialized for support. Cartilage occurs where flexibility is required, while bone resists deformation. Each has all the common features of connective tissue, which includes ground substance, fibers and cells.
CARTILAGE
Three types of cartilage can be distinguished based on the relative amount of fibers and ground substance: hyaline cartilage, elastic cartilage and fibrocartilage.
Hyaline Cartilage
Hyaline cartilage contains fibers of type II collagen within abundant ground substance.

BONE
Bone is hard and rigid. It is mineralized and forms the supportive framework for the body. Morphologically, bone is organized into two types: compact bone and spongy (cancellous or trabecular) bone.
Bone also serves as a reservoir for Ca2+ and PO42-.
