Question 2

A patient presents with a fracture in the shaft of the femur. Which type of bone cell is primarily responsible for the resorption of bone tissue during the healing process?

Accepted Answer

Osteoclasts

Question 3

Which equation correctly represents the relationship between bone mass ($$M$$), bone formation rate ($$F$$), and bone resorption rate ($$R) $$over time?

Accepted Answer

$$M = F - R$$

Question 4

Which of the following is a common consequence of osteoporosis?

Accepted Answer

Compression fractures of the vertebrae

Question 5

A patient is diagnosed with scoliosis. Which term best describes this condition?

Accepted Answer

Abnormal lateral curvature of the spine

Question 6

Which of the following best distinguishes axial from appendicular skeleton components?

Accepted Answer

Axial skeleton includes the skull, vertebral column, and rib cage; appendicular skeleton includes the limbs and girdles.

Question 7

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

Accepted Answer

Facilitating growth in length during childhood

Question 8

Which of the following best describes the microscopic structure of compact bone?

Accepted Answer

It contains osteons with concentric lamellae surrounding a central canal.

Question 9

Which of the following scenarios best illustrates the difference between tendon and ligament?

Accepted Answer

A tendon attaches muscle to bone, while a ligament connects bone to bone.

Question 10

Which of the following muscle types is under voluntary control?

Accepted Answer

Skeletal muscle

Question 11

During muscle contraction, which equation best represents the relationship between force ($$F$$), cross-sectional area ($$A$$), and muscle tension ($$T$$)?

Accepted Answer

$$F = T 	imes A$$

Question 12

Which of the following best describes the role of the neuromuscular junction?

Accepted Answer

It is the site where a motor neuron communicates with a muscle fiber to initiate contraction.

Question 13

A patient with muscle atrophy is most likely to experience which of the following?

Accepted Answer

Decrease in muscle mass and strength

Question 14

Which of the following best describes the difference between origin and insertion of a muscle?

Accepted Answer

Origin is the fixed attachment; insertion is the movable attachment.

Question 18

Which equation best represents the calculation of muscle force ($$F) $$given muscle cross-sectional area ($$A) $$and specific tension ($$\sigma$$)?

Accepted Answer

$$F = \sigma 	imes A$$

Question 19

Which of the following is a distinguishing feature of cardiac muscle compared to skeletal muscle?

Accepted Answer

Cardiac muscle cells are connected by intercalated discs.

Question 20

A soccer player tears a ligament in the knee. Which of the following best describes the function of ligaments?
