Question 1

Which of the following best describes the main function of epithelial tissue in the human body?

Accepted Answer

Covering surfaces and lining cavities to form protective barriers

Question 2

A patient suffers a deep cut that damages both the epidermis and dermis. Which sequence correctly represents the steps of tissue repair?

Accepted Answer

Inflammation \rightarrow Organization \rightarrow Regeneration and Fibrosis

Question 3

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

Accepted Answer

Presence of intercalated discs and involuntary control

Question 4

Which bone cell type is primarily responsible for bone resorption during remodeling?

Accepted Answer

Osteoclast

Question 5

A long bone fracture is repaired through several steps. Which step involves the formation of a fibrocartilaginous callus?

Accepted Answer

Fibrocartilaginous callus formation

Question 6

Which equation best represents the relationship between force generated by a muscle and the number of motor units recruited?

Accepted Answer

$$F = k 	imes MU$$

Question 7

Which of the following best explains why bones are composed of both organic and inorganic components?

Accepted Answer

Organic components provide flexibility, while inorganic components provide hardness.

Question 8

During muscle contraction, which sequence correctly describes the role of calcium ions ($$Ca^{2+}) $$and acetylcholine (Ach)?

Accepted Answer

Ach stimulates sarcolemma, $$Ca^{2+} is $$released from sarcoplasmic reticulum

Question 9

Which of the following best describes endochondral ossification?

Accepted Answer

Bone replaces hyaline cartilage models

Question 10

A patient with osteoporosis is at increased risk for fractures because:

Accepted Answer

Bone resorption exceeds bone deposition, reducing bone density

Question 11

Which of the following is a characteristic unique to smooth muscle tissue?

Accepted Answer

Spindle-shaped cells and involuntary control

Question 12

Which formula best represents the rate of bone remodeling as influenced by hormonal and mechanical factors?

Accepted Answer

$$R = h + m$$

Question 13

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

Accepted Answer

Production of hormones

Question 14

A muscle fiber is stimulated repeatedly at a high frequency, resulting in a sustained contraction. This phenomenon is known as:

Accepted Answer

Tetanic contraction

Question 15

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

Accepted Answer

Compact bone is dense and forms the outer layer, spongy bone is porous and found inside

Question 16

Which equation best represents the relationship between muscle fatigue ($$MF$$), ATP availability ($$A$$), and lactic acid accumulation ($$L$$)?

Accepted Answer

$$MF = \frac{L}{A}$$

Question 17

Which of the following is a real-life example of an isometric muscle contraction?

Accepted Answer

Holding a plank position

Question 18

Which tissue type is most likely to be involved in rapid communication between different parts of the body?

Accepted Answer

Nervous tissue

Question 19

Which of the following best explains the process of bone growth at the epiphyseal plate?

Accepted Answer

Chondrocytes proliferate and are replaced by bone tissue

Question 20

Which of the following is a plausible consequence of Paget’s disease on bone structure?

Accepted Answer

Bones exhibit excessive and disorganized remodeling
