Question 1

Which of the following statements best explains why cartilage heals more slowly than bone after injury?

Accepted Answer

Cartilage is avascular and lacks nerves, limiting nutrient supply and repair mechanisms.

Question 2

A patient presents with a fracture in the shaft of their femur. Which anatomical term describes this region?

Accepted Answer

Diaphysis

Question 3

Which type of cartilage is most likely to be found in the menisci of the knee, and what property does it provide?

Accepted Answer

Fibrocartilage; provides strength and compressibility

Question 4

During bone growth, which process increases the thickness of bones?

Accepted Answer

Appositional growth

Question 5

Which bone cell is primarily responsible for bone resorption, and what is the main function of this process?

Accepted Answer

Osteoclast; breaks down bone matrix to release minerals

Question 6

A child with rickets is likely to have bones that are soft and deformed. Which component of bone is deficient, and what is its chemical formula?

Accepted Answer

Hydroxyapatite; $$Ca_{10}(PO_4$)_6(OH)_2$$

Question 7

Which of the following best describes the structural unit of compact bone?

Accepted Answer

Osteon (Haversian system)

Question 8

A 60-year-old woman is diagnosed with osteoporosis. Which of the following best explains the pathophysiology of this disorder?

Accepted Answer

Loss of bone mass due to increased bone resorption and decreased bone formation

Question 9

Which process is responsible for the formation of flat bones such as those in the skull?

Accepted Answer

Intramembranous ossification

Question 10

If a bone fracture occurs, which step immediately follows hematoma formation in the repair process?

Accepted Answer

Fibrocartilaginous callus formation

Question 11

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

Accepted Answer

Compact bone is dense and organized into osteons, while spongy bone consists of trabeculae aligned along lines of stress.

Question 12

Which bone membrane contains osteogenic cells and is essential for bone growth and repair?

Accepted Answer

Periosteum

Question 13

A long bone grows in length primarily at which structure during childhood?

Accepted Answer

Epiphyseal plate

Question 14

Which of the following is NOT a function of bone?

Accepted Answer

Production of hormones

Question 15

Which type of bone is classified as irregular, and what is an example?

Accepted Answer

Vertebra; irregular bone

Question 16

A patient with Paget’s disease is experiencing abnormal bone remodeling. Which of the following best describes the consequence of this disease?

Accepted Answer

Disorganized bone structure and weakened bones

Question 17

Which equation best represents the mineral responsible for bone hardness?

Accepted Answer

$$Ca_{10}(PO_4$)_6(OH)_2$$

Question 18

Which of the following scenarios best illustrates appositional growth in bone?

Accepted Answer

An athlete’s bones increase in diameter due to repeated mechanical stress.

Question 19

Which component of bone matrix is primarily responsible for its tensile strength?

Accepted Answer

Collagen fibers

Question 20

A medical student is asked to identify the tissue that surrounds cartilage and provides nutrients via diffusion. Which tissue should they select?

Accepted Answer

Perichondrium
