ii. Fibrocartilage
Thick bundles of collagen fibres are seen within the extracellular matrix of fibrocartilage as well as chondrocytes scattered throughout. There is no perichondrium. This tissue is the strongest of the three types of cartilage displaying a combination of strength and rigidity.
Example:
iii. Elastic cartilage
Chondrocytes are located within the network of elastic fibres of the extracellular matrix. There is a perichondrium. This tissue maintains strength and elasticity of certain structures.
Example:
D. Bone: composed of osteocytes in a calcified matrix
Bones are one part of the skeletal system. Bones store calcium and phosphorus; house red bone marrow, which produces blood cells; and contain yellow marrow, a storage site for triglycerides. Bones are organs composed of several different CTs including osseous tissue, the periosteum, red and yellow marrow, and the endosteum. Bone tissue is classified as either Compact or Spongy depending on how its ECM and cells are organized.
