CONNECTIVE TISSUES 3: 1. CARTILAGE 2. OSSIFICATION 3. BONE

1. CARTILAGE - hyaline cartilage - elastic cartilage - fibrous cartilage

Hyaline cartilage Trachea ankle surfaces trachea, larynx, nose cartilage end parts of ribs * Cellular elements * Collagen type 2 * Ground substance (proteoglycans + H2O)

Hyaline cartilage perichondrium chondroblasts

Hyaline cartilage chondrocytes lacuna teritorium interteritorium Isogenous group

Elastic cartilage epiglottis *FIBERS: Elastic + collagen type 2 *small amount of ground substance * more individual chondrocytes epiglottis

Elastic cartilage perichondrium chondroblasts

Elastic cartilage teritorium interteritorium chondrocytes Isogenous group

Fibrous cartilage meniscus * Without perichondrium * collagen type 1 * small amount of ground substance * more individual chondrocytes

Fibrous cartilage Isogenous group small amount of ground substance collagen fibers

2. OSSIFICATION - indirect - direct

INDIRECT OSSIFICATION

INDIRECT OSSIFICATION Zone of ossification Zone of hypertophy Zone of proliferation Zone of reserve cartilige Zone of calcification Zone of erosion

DIRECT OSSIFICATION mesenchymal tissue osteocyte osteoblast bone matrix

3. BONE TISSUE
