Skeletal System - Bone Structure

Front

What is the primary function of long bones in the skeletal system?

Back

Long bones primarily support the weight of the body and facilitate movement.

Front

Which bones are classified as long bones?

Back

Examples of long bones include the femur, humerus, and tibia.

Front

What is the structure that contains blood vessels and nerves in long bones?

Back

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

Front

What type of bone tissue is dense and forms the outer layer of bones?

Back

Compact bone is the dense tissue that forms the outer layer of bones.

Front

What is the spongy bone, and where is it typically found?

Back

Spongy bone, or cancellous bone, is found at the ends of long bones and in the interiors of others, providing structural support and flexibility.

Front

What is the role of marrow in bones?

Back

Marrow is soft connective tissue found in the spaces of bones, responsible for producing blood cells.

Front

What are epiphyses in the context of long bones?

Back

Epiphyses are the ends of long bones, which articulate with other bones at joints.

Front

What is the difference between compact bone and spongy bone?

Back

Compact bone is dense and forms the outer layer, while spongy bone is lighter, less dense, and contains many spaces.

Front

What is the significance of the periosteum in bone structure?

Back

The periosteum is a dense layer of vascular connective tissue that covers the bones, providing protection and serving as an attachment point for muscles.

Front

What is the function of osteocytes in bone tissue?

Back

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