SKELETAL TISSUE As an example of Connective Tissue

CARTILAGE Chondrocytes Matrix – Glycoproteins – Collagen – Elastic Fibers

Perichondrium Nonvascular

Types of Cartilage

Hyaline

Types of Cartilage Elastic

Types of Cartilage Fibrocartilage

BONE CELLS – Osteocytes – Osteoblasts – Osteoclasts

BONE Intercellular substance – Calcium phosphate – Hydroxyapatite crystals – Collagen

BONE Vascular Periosteum General Functions

Typical Long Bone Diaphysis Epiphysis Metaphysis Articular Cartilage Periosteum Marrow = Medullary cavity Endosteum

Compact Bone OSTEON – Central (Haversian) Canal – Perforating (Volkmann’s Canal) – Lamellae – Osteocytes in lacunae

Spongy = Cancellous Bone Trabeculae

OSSIFICATION Intramembranous
