Skeletal System Microanatomy Quiz

What is the structure and function of an osteon?

• The function of an osteon is to provide sensory perception and transmit nerve impulses within the bone.

• The structure of an osteon consists of irregularly arranged layers of bone matrix called lamellae, surrounding a central cavity called the Haversian canal.

• The structure of an osteon consists of concentric layers of bone matrix called lamellae, surrounding a central canal called the Haversian canal. The function of an osteon is to provide structural support and allow for the transport of nutrients and waste products within the bone.

• The structure of an osteon consists of concentric layers of cartilage called lamellae, surrounding a central canal called the Haversian canal.

How does bone growth and development occur?

• Bone growth and development occur through ossification.

• Bone growth and development occur through muscle contraction.

• Bone growth and development occur through cartilage formation.

• Bone growth and development occur through cell division.

What is the process of bone remodeling and repair?

• Bone remodeling and repair is the process of increasing the density of existing bone tissue without replacing it.

• Bone remodeling and repair is the process of replacing old bone tissue with muscle tissue.

• Bone remodeling and repair is the process of removing bone tissue without replacing it.

• Bone remodeling and repair is the process of replacing old bone tissue with new bone tissue through bone resorption and formation.

What are the different types of bone cells and their functions?

• The different types of bone cells are osteoblasts, osteocytes, and osteoclasts. Their functions are as follows: osteoblasts are responsible for bone formation, osteocytes maintain bone tissue, and osteoclasts are involved in bone resorption.

• The different types of bone cells are osteoclasts, osteocytes, and osteoblasts. Their functions are as follows: osteoclasts are responsible for bone resorption, osteocytes maintain bone tissue, and osteoblasts are involved in bone formation.

What is the basic unit of structure in compact bone?

• Adipocyte

• Osteon or Haversian system

• Chondrocyte

• Myofibril

What factors influence bone growth and development?

• Weather, geography, and time of day

• Genetics, nutrition, physical activity, hormones, and age.

• Favorite color, music taste, and shoe size

• Number of pets, favorite food, and hair color

Explain the process of bone remodeling.

• Bone remodeling is the continuous process of removing old bone tissue and forming new bone tissue.

• Bone remodeling is the process of replacing cartilage with bone tissue.

• Bone remodeling is the process of repairing damaged bone tissue.

• Bone remodeling is the process of increasing bone density.

What are the functions of osteoblasts and osteoclasts?

• Osteoblasts resorb bone, while osteoclasts form bone.

• Osteoblasts and osteoclasts have no functions in bone formation or resorption.

• Osteoblasts form cartilage, while osteoclasts resorb bone.

• Osteoblasts form bone, while osteoclasts resorb bone.

Name and describe the different parts of a long bone.

• A long bone has one main part: the shaft.

• A long bone has three main parts: the diaphysis, the epiphysis, and the metaphysis.

• A long bone has two main parts: the diaphysis and the epiphysis.

• A long bone has four main parts: the periosteum, the endosteum, the medullary cavity, and the articular cartilage.
