2 types of supportive connective tissue

Cartilage & bone

3 types of cartilage

hyaline, Fibrocartilage & elastic

What cells make up cartilage?

Chondrocytes

What is interstitial growth?

Growth that increases length of cartilage/bone.

What is appositional growth?

Growth that increases width/thickness.

Where is hyaline cartilage found?

end of long bones & respiratory tract

What is Fibrocartilage function?

Provides shock protection.

Where is elastic cartilage found?

External ear; it allows the ear to bed and return to its shape.

What are concentric lamellae?

Rings of bone tissue surrounding the central canal.

What are canaliculi?

Tiny channels that allow communication between osteocytes.

What are trabeculae?

What is the periosteum?

Outer covering of bone.

What is endosteum?

Membrane lining the inner surfaces of bone.

What does the volkman’s canal do?

What is the final stage of fracture healing?

Compact bone formation.

What is the order of fracture healing?

Hematoma - callus - spongy bone - compact bone.
