Question 1

Which of the following best describes the difference between axial and appendicular skeletons?

Accepted Answer

Axial skeleton consists of bones that form the long axis of the body, such as the skull, vertebral column, and rib cage; appendicular skeleton consists of bones of the limbs and girdles.

Question 2

Which of the following is NOT a function of bone tissue?

Accepted Answer

Production of hormones for metabolism

Question 3

A patient’s X-ray shows a gradual loss of bone density over several years. Which process is most likely impaired?

Accepted Answer

Bone remodeling

Question 4

Which cell type is primarily responsible for bone resorption?

Accepted Answer

Osteoclasts

Question 5

Which equation best represents the relationship between calcium homeostasis and bone tissue?

Accepted Answer

$$Ca^{2+}$$_{bone} \leftrightarrow $$Ca^{2+}$$_{blood}$$

Question 6

Which of the following best describes the process of endochondral ossification?

Accepted Answer

Bone replaces a pre-existing cartilage model during development.

Question 7

A 70-year-old patient is diagnosed with osteoporosis. Which of the following best explains the impact of this disease on bone tissue?

Accepted Answer

Increased bone resorption and decreased bone formation result in fragile bones.

Question 8

Which of the following is a major inorganic component of bone matrix?

Accepted Answer

Hydroxyapatite

Question 9

During bone remodeling, which equation best describes the balance between bone formation and resorption?

Accepted Answer

$$\Delta Bone_{mass} = Bone_{formation} - Bone_{resorption}$$

Question 10

Which of the following scenarios best illustrates the effect of hormones on bone growth?

Accepted Answer

A child with excess growth hormone develops abnormally long bones.

Question 11

Which of the following is a correct sequence in the process of fracture healing?

Accepted Answer

Hematoma formation, fibrocartilaginous callus, bony callus formation, bone remodeling

Question 12

Which of the following best explains why bone density decreases with age?

Accepted Answer

Osteoclast activity increases while osteoblast activity decreases.

Question 13

Which of the following is a correct description of compact bone?

Accepted Answer

It is dense and forms the outer layer of all bones.

Question 14

Which of the following best describes the role of osteocytes?

Accepted Answer

They maintain bone tissue and communicate mechanical stress.

Question 15

A radiologist is assessing a child’s X-ray and notes the presence of an epiphyseal plate. What does this indicate?

Accepted Answer

The child’s bones are still growing in length.

Question 16

Which of the following is a correct statement about bone diseases?

Accepted Answer

Osteoporosis is characterized by decreased bone mass and increased fracture risk.

Question 17

Which of the following best describes the function of the periosteum?

Accepted Answer

It covers the outer surface of bone and contains blood vessels and nerves.

Question 18

Which equation best represents the rate of bone growth in children?

Accepted Answer

$$Rate_{growth} = \frac{\Delta Length}{\Delta Time}$$

Question 19

Which of the following best explains the difference between spongy and compact bone?

Accepted Answer

Spongy bone contains trabeculae and is found at the ends of long bones; compact bone is dense and forms the outer layer.

Question 20

Which of the following best describes the process of bone aging over the lifespan?

Accepted Answer

Bone mass peaks in early adulthood and gradually declines with age.
