Macro and Micro Bone Anatomy

Front

What are osteoclasts?

Back

Osteoclasts are specialized bone cells responsible for the resorption and dissolution of old bone matrix.

Front

What are osteocytes?

Back

Osteocytes are mature bone cells that maintain bone tissue and are found within lacunae.

Front

What is the function of osteoblasts?

Back

Osteoblasts are bone-forming cells that synthesize and secrete the bone matrix.

Front

What is the primary function of osteons?

Back

Osteons are the structural units of compact bone, consisting of concentric lamellae surrounding a central canal.

Front

What are lamellae?

Back

Lamellae are thin layers of bone matrix that form the structure of osteons.

Front

What are lacunae?

Back

Lacunae are small cavities in bone tissue that house osteocytes.

Front

What are canaliculi?

Back

Canaliculi are tiny channels that connect lacunae and allow for communication and nutrient exchange between osteocytes.

Front

What type of bone is a vertebra?

Back

A vertebra is classified as an irregular bone due to its complex shape.

Front

What is the role of osteoblasts in bone remodeling?

Back

Osteoblasts play a crucial role in bone remodeling by forming new bone tissue.

Front

What is the difference between compact bone and spongy bone?

Back

Compact bone is dense and forms the outer layer of bones, while spongy bone is lighter and contains trabecular structures.
