Bone Structure Quiz

Study Notes

Central (Haversian) Canal

Located in the center of the osteon, which is the functional unit of compact bone
Houses blood vessels, nerves, and lymphatic tissue
Responsible for providing nutrients, oxygen, and removing waste products from bone cells
Plays an important role in communication and signaling between bone cells

Lacunae

Small cavities within both bone and cartilage
House chondrocytes in cartilage and osteocytes in bone
Crucial for the maintenance and health of these tissues
Osteocytes within lacunae communicate with each other to regulate bone density

Osteocytes

Mature bone cells residing in lacunae
Responsible for maintaining bone tissue by regulating bone density and mineral content
Communicate with other osteocytes through canaliculi

Concentric Lamellae

Layers of mineralized matrix surrounding the central canal, forming ring-like structures
Provide structural support and strength to bone
Contain collagen fibers and minerals arranged in a specific way to resist stress and strain

Canaliculi

Tiny channels connecting lacunae to each other and the central canal
Facilitate the exchange of nutrients, waste products, and signaling molecules between osteocytes and the blood supply
Essential for the communication and function of osteocytes

Trabeculae

Thin, bony plates found in spongy bone, creating a lattice-like structure
Provide structural support and distribute forces throughout the bone
Help reduce weight and maintain bone strength

Description

Test your knowledge on the central canal, lacunae, osteocytes, and concentric lamellae. This quiz covers the essential components and functions of bone tissue, highlighting their roles in maintaining bone health and communication. Perfect for students of anatomy and physiology.
