Long bone & Osteon Review Kramer

Front

What is the periosteum?

Back

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

Front

What is the medullary cavity?

Back

The medullary cavity is the central cavity of bone shafts where red and yellow bone marrow is stored.

Front

What is the epiphysis?

Back

The epiphysis is the end part of a long bone, initially growing separately from the shaft.

Front

What are canaliculi?

Back

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

Front

What are lacunae?

Back

Lacunae are small cavities in bone that house osteocytes.

Front

What are osteons?

Back

Osteons, or Haversian systems, are the fundamental functional units of compact bone, consisting of a central canal surrounded by concentric rings of bone matrix.

Front

What are lamellae?

Back

Lamellae are thin layers of bone matrix that form the structure of osteons.

Front

What is the diaphysis?

Back

The diaphysis is the shaft or central part of a long bone.

Front

What are osteocytes?

Back

Osteocytes are mature bone cells that maintain the bone matrix and communicate with other bone cells.

Front

What are Volkmann's canals?

Back

Volkmann's canals are channels in bone that transmit blood vessels and communicate with Haversian canals.
