Micro Bone Anatomy

Front

What are lacunae in bone anatomy?

Back

Lacunae are small cavities in bone tissue that house osteocytes.

Front

What are osteocytes and where are they located?

Back

Osteocytes are mature bone cells located within the lacunae.

Front

What are canaliculi in the context of bone structure?

Back

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

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 lamellae.

Front

What are Central (Haversian) canals?

Back

Central (Haversian) canals are the central channels in osteons that contain blood vessels and nerves.

Front

How do osteocytes communicate with each other?

Back

Osteocytes communicate through the canaliculi that connect their lacunae.

Front

What is the role of osteoblasts in bone tissue?

Back

Osteoblasts are cells responsible for bone formation and the synthesis of 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 remodeling.

Front

What is the composition of bone matrix?

Back

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

Front

What is the significance of the Haversian system in bone structure?

Back

The Haversian system allows for the efficient transport of nutrients and waste products, maintaining bone health.
