Microscopic Bone Structure

Front

What is the function of lacunae in bone structure?

Back

Lacunae are small cavities in bone that house osteocytes, the mature bone cells.

Front

What are osteocytes?

Back

Osteocytes are mature bone cells that maintain bone tissue and reside in lacunae.

Front

What is the role of canaliculi in bone?

Back

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

Front

Define lamellae in the context of bone structure.

Back

Lamellae are concentric rings of bone matrix that surround the Haversian canal, providing structural support.

Front

What is the Haversian canal?

Back

The Haversian canal is a central channel in bone that contains blood vessels and nerves.

Front

What are osteoblasts?

Back

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

Front

What are osteoclasts?

Back

Osteoclasts are cells that break down bone tissue, playing a crucial role in bone remodeling.

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 found inside bones, containing red marrow.

Front

What is the significance of the Volkmann's canal?

Back

Volkmann's canals are channels that connect Haversian canals and allow for the passage of blood vessels and nerves between different osteons.

Front

How do osteocytes communicate with each other?

Back

Osteocytes communicate through the canaliculi, which connect their lacunae.
