Anatomy of a Long Bone Quiz

What is the structure of a long bone?

• The structure of a long bone consists of a diaphysis, epiphysis, metaphysis, periosteum, compact bone, spongy bone, medullary cavity, and blood vessels.

• The structure of a long bone consists of a diaphysis, epiphysis, metaphysis, periosteum, compact bone, spongy bone, medullary cavity, and articular cartilage.

• The structure of a long bone consists of a diaphysis, epiphysis, metaphysis, periosteum, compact bone, spongy bone, medullary cavity, and nerve tissue.

• The structure of a long bone consists of a diaphysis, epiphysis, metaphysis, periosteum, compact bone, spongy bone, medullary cavity, and muscle tissue.

Name the components of a long bone.

• diaphysis, epiphysis, metaphysis, periosteum, endosteum, medullary cavity, articular cartilage, compact and spongy bone

• shaft, head, neck, periosteum, endosteum, marrow cavity, cartilage, hard and soft bone

• diaphysis, epiphysis, metaphysis, periosteum, endosteum, medullary cavity, articular cartilage, compact and spongy bone

• cortex, apophysis, epiphysis, periosteum, endosteum, marrow cavity, articular cartilage, dense and porous bone

What are the functions of a long bone?

• Long bones do not produce blood cells or store minerals

• Long bones support the weight of the body, facilitate movement, produce blood cells, and store minerals.

• Long bones are not involved in movement

• Long bones are only used for protection

Which part of a long bone contains red bone marrow?

• Compact bone

• Yellow bone marrow

• Periosteum

• Spongy or cancellous bone

What is the outermost layer of a long bone called?

• medullary cavity

• endosteum

• epiphysis

• periosteum

What is the purpose of the periosteum?

• The purpose of the periosteum is to secrete hormones that regulate bone growth

• The purpose of the periosteum is to act as a cushion for the bone

• The purpose of the periosteum is to provide a pathway for blood vessels to enter the bone

• The purpose of the periosteum is to provide a protective outer lining that helps with repair and maintenance of the bone and to serve as a site for muscle and ligament attachment; the periosteum has nutrient arteries, veins, and nerves that are interwoven through it that provide the interior bone with nutrients and oxygen for growth and carry away waste. When we break a bone, the reason we feel pain is because we have ruptured/broken through nerves within the periosteum.

Which type of bone cells are responsible for bone formation?

• Osteoblasts

• Chondrocytes

• Osteocytes

• Osteoclasts

What is the central cavity of a long bone called?

• Periosteum cavity

• Medullary cavity

• Haversian canal

• Central canal

What is the function of yellow bone marrow?

• Yellow bone marrow stores calcium and produces blood cells.

• Yellow bone marrow stores fat and produces blood cells.

• Yellow bone marrow stores fat and produces bone cells.

• Yellow bone marrow stores fat and produces muscle cells.

What is the role of osteoclasts in bone remodeling?

• Osteoclasts break down old or damaged bone tissue in bone remodeling.

• Osteoclasts build new bone tissue in bone remodeling.

• Osteoclasts only break down bone tissue in young individuals.

• Osteoclasts have no role in bone remodeling.
