Question 5

The bone matrix is primarily composed of which two substances?

Accepted Answer

Collagen fibers and hydroxyapatite

Question 6

Accepted Answer

Osteoclast

Question 7

A patient is diagnosed with osteoporosis, a condition characterized by decreased bone density. Which part of the bone is most affected by this disease?

Accepted Answer

Spongy bone (trabecular bone)

Question 8

Which of the following statements about compact bone is correct?

Accepted Answer

It contains osteons (Haversian systems) that provide strength

Question 9

The periosteum is essential for bone health because it:

Accepted Answer

Contains blood vessels and nerves that nourish bone tissue

Question 10

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

Accepted Answer

Bone replaces a hyaline cartilage model

Question 11

A 12-year-old child is experiencing rapid growth. Which region of the long bone is primarily responsible for this increase in length?

Accepted Answer

Epiphyseal plate (growth plate)

Question 12

Which formula correctly represents the calculation of bone mineral density (BMD) if bone mass is $$M$$ and bone volume is $$V$$?

Accepted Answer

$$	ext{BMD} = \frac{M}{V}$$

Question 13

During bone growth, which cell type is responsible for depositing new bone matrix on the outer surface of the diaphysis?

Accepted Answer

Osteoblasts

Question 14

A patient with leukemia is undergoing a bone marrow biopsy. Which type of bone marrow is most likely to be sampled for hematopoietic (blood cell) analysis?

Accepted Answer

Red bone marrow

Question 15

Which of the following best explains why flat bones, such as those in the skull, are more likely to form via intramembranous ossification rather than endochondral ossification?

Accepted Answer

They develop directly from mesenchymal tissue without a cartilage model

Question 16

A patient presents with a bone infection that has spread to the inner lining of the bone cavity. Which structure is most likely affected?

Accepted Answer

Endosteum

Question 17

Which of the following scenarios best illustrates the role of bone markings in clinical practice?

Accepted Answer

A physician palpates the greater trochanter to locate the site for an intramuscular injection

Question 18

Which of the following is a correct sequence of events in endochondral ossification?

Accepted Answer

Cartilage model develops → cartilage calcifies → primary ossification center forms → medullary cavity develops

Question 19

If a bone is subjected to increased mechanical stress, which of the following best describes the expected physiological response according to Wolff's Law?

Accepted Answer

Bone will increase in density and strength at the site of stress

Question 20

A 30-year-old athlete suffers a fracture in the shaft of the humerus. Which region of the long bone is most likely involved?

Accepted Answer

Diaphysis
