Microscopic Bone Test Review

Front

What are Volkmann's canals?

Back

Volkmann's canals, also known as perforating canals, are blood vessels that lie at right angles to the central canal, connecting the blood and nerve supply of the periosteum to the central canal.

Front

Where do osteocytes reside?

Back

Osteocytes reside in small spaces called lacunae within the bone matrix.

Front

What is an osteon?

Back

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

Front

What are lamellae?

Back

Lamellae are the rings of bone matrix that surround the central (Haversian) canal in an osteon.

Front

What is the function of osteocytes?

Back

Osteocytes are mature bone cells that maintain bone tissue and communicate with other bone cells to regulate bone remodeling.

Front

What is the role of osteoblasts?

Back

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

Front

What is the function of osteoclasts?

Back

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

Front

What is the periosteum?

Back

The periosteum is a dense layer of vascular connective tissue that envelops the bones except at the surfaces of the joints.

Front

What is the central canal?

Back

The central canal, also known as the Haversian canal, contains blood vessels and nerves that supply the bone.

Front

What are canaliculi?

Back

Canaliculi are tiny channels that connect lacunae to each other and to the central canal, allowing for nutrient and waste exchange.
