Micro Bone Anatomy

Front

What is the function of Central (Haversian) canals in bone anatomy?

Back

Central (Haversian) canals contain blood vessels and nerves that provide nutrients and signals to the bone.

Front

What are osteocytes and where are they located?

Back

Osteocytes are mature bone cells that are located within the lacunae of bone tissue.

Front

What is the role of canaliculi in bone structure?

Back

Canaliculi are small channels that connect osteocytes and allow for the exchange of nutrients and waste.

Front

What are lamellae in the context of bone anatomy?

Back

Lamellae are thin layers of bone matrix that form the structural units of compact bone.

Front

What is an osteon and what is its significance in bone structure?

Back

An osteon, or Haversian system, is the fundamental functional unit of compact bone, consisting of a central canal surrounded by concentric lamellae.

Front

How do osteocytes communicate with each other?

Back

Osteocytes communicate through the canaliculi, which connect their cell processes.

Front

What is the composition of bone matrix?

Back

The bone matrix is composed of organic components (like collagen fibers) and inorganic components (like hydroxyapatite crystals).

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, has a porous structure, and is found inside bones.

Front

What is the significance of the periosteum in bone anatomy?

Back

The periosteum is a dense layer of vascular connective tissue that covers the outer surface of bones, providing protection and serving as an attachment point for muscles.

Front

What role do osteoblasts play in bone formation?

Back

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