$$\text{Bone mass} = \text{Volume} \times \text{Density}$$

Question 1

Which structure in a long bone is responsible for housing stem cells and producing red blood cells?

Accepted Answer

Epiphysis

Question 2

What is the primary function of the periosteum in bone tissue?

Accepted Answer

To provide a tough, connective tissue layer for protection and attachment of tendons

Question 3

Which of the following best describes the arrangement of osteocytes in compact bone?

Accepted Answer

Arranged in rings within cylindrical structures called osteons

Question 4

A patient suffers a fracture in the diaphysis of their femur. Which type of bone marrow is most likely affected?

Accepted Answer

Yellow bone marrow

Question 5

Which structure allows osteocytes to exchange nutrients and communicate with each other?

Accepted Answer

Canaliculi

Question 6

If the Haversian canal in an osteon is blocked, what is the most likely consequence?

Accepted Answer

Nutrient supply to osteocytes will be compromised

Question 7

Which equation best represents the mineralization process of bone tissue?

Accepted Answer

$$Ca^{2+}$$ + $$PO_4$$^{3-} \rightarrow $$Ca_3$$($$PO_4)_2$

Question 8

Which part of the long bone is primarily composed of spongy bone and contains red bone marrow?

Accepted Answer

Epiphysis

Question 9

In a histological section, you observe osteocytes embedded in lacunae with canaliculi connecting them. What is the main function of these canaliculi?

Accepted Answer

To facilitate nutrient and waste exchange between osteocytes

Question 10

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

Accepted Answer

Producing red blood cells

Question 11

A bone biopsy reveals cells trapped in hollow chambers surrounded by calcium phosphate. What are these chambers called?

Accepted Answer

Lacunae

Question 12

Which structure is most likely to be damaged if a bone is fractured at the periosteum?

Accepted Answer

Blood vessels and nerves

Question 13

Which of the following best describes the function of osteocytes?

Accepted Answer

They maintain bone tissue and exchange nutrients via canaliculi

Question 14

A patient with leukemia receives a bone marrow transplant. Which part of the long bone is most likely targeted for the transplant?

Accepted Answer

Epiphysis

Question 15

Which structure is responsible for the hardness of bone tissue?

Accepted Answer

Calcium phosphate matrix

Question 16

If a mutation disrupts the formation of canaliculi, what is the most likely effect on bone tissue?

Accepted Answer

Osteocytes will be unable to exchange nutrients efficiently

Question 17

Which of the following equations best represents the relationship between bone mass and mineral content?

Accepted Answer

$$	ext{Bone mass} = 	ext{Volume} 	imes 	ext{Density}$$

Question 18

Which structure is most important for the attachment of tendons and ligaments to bone?

Accepted Answer

Periosteum

Question 19

Which of the following is a correct sequence for the flow of nutrients to osteocytes in compact bone?

Accepted Answer

Haversian canal → canaliculi → lacunae → osteocytes

Question 20

Which of the following best explains why the diaphysis is composed mainly of compact bone?

Accepted Answer

To provide strength and support for weight-bearing
