Human Anatomy and Physiology the Skeletal System

Front

What is the central Haversian canal?

Back

The central Haversian canal is a channel in the center of an osteon that contains blood vessels and nerves, providing nutrients and communication to the bone.

Front

What is the periosteum?

Back

The periosteum is a tough layer of connective tissue that surrounds the bone, allowing for attachment to tendons and ligaments.

Front

What are canaliculi?

Back

Canaliculi are small channels that connect osteocytes within the bone, allowing for communication and nutrient exchange.

Front

What is a hematoma?

Back

A hematoma is a localized collection of blood outside of blood vessels, often forming at the site of a bone fracture.

Front

What is the function of hydroxyapatite in bones?

Back

Hydroxyapatite provides strength and hardness to bones, making them resilient to stress.

Front

What is an osteon?

Back

An osteon, or Haversian system, is the basic structural unit of compact bone, consisting of a central canal surrounded by concentric rings of bone matrix.

Front

What are osteocytes?

Back

Osteocytes are mature bone cells that maintain bone tissue and communicate with other bone cells through canaliculi.

Front

What is the diaphysis of a bone?

Back

The diaphysis is the long, tubular shaft of a long bone, providing structural support and housing the medullary cavity.

Front

What are epiphyses?

Back

Epiphyses are the ends of long bones, which articulate with other bones and are covered with articular cartilage.

Front

What is the epiphyseal plate?

Back

The epiphyseal plate, or growth plate, is a layer of cartilage where bone growth occurs in children and adolescents.
