Histology of Bone Tissue

Front

What are canaliculi?

Back

Canaliculi are small channels in bone tissue that connect lacunae, allowing for communication and nutrient exchange between osteocytes.

Front

What is the function of osteons in compact bone?

Back

Osteons, or Haversian systems, are the structural units of compact bone, providing strength and support through their concentric lamellae and central canals.

Front

What are the types of lamellae found in compact bone?

Back

The types of lamellae in compact bone include concentric lamellae, interstitial lamellae, inner circumferential lamellae, and outer circumferential lamellae.

Front

What are Sharpey's fibers?

Back

Sharpey's fibers are collagen fibers that anchor the periosteum to the underlying bone, providing stability and support.

Front

What is the medullary cavity?

Back

The medullary cavity is the central cavity within long bones that contains bone marrow, which is involved in blood cell production.

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, less dense, and contains trabeculae that house bone marrow.

Front

What are trabeculae?

Back

Trabeculae are the small, rod-like structures in spongy bone that create a network for support and house bone marrow.

Front

What is the role of interstitial lamellae?

Back

Interstitial lamellae fill the spaces between osteons in compact bone, providing additional strength and support.

Front

What is the significance of the Haversian canal?

Back

The Haversian canal contains blood vessels and nerves, providing nutrients and signaling to the bone tissue.

Front

What is the outer circumferential lamellae?

Back

Outer circumferential lamellae are layers of bone tissue that encircle the outer surface of compact bone, providing structural support.
