Question 1

Which of the following best describes the principle of complementarity in human anatomy and physiology?

Accepted Answer

Function always reflects structure; what a structure can do depends on its specific form.

Question 2

Which feedback mechanism is primarily responsible for maintaining homeostasis in the human body?

Accepted Answer

Negative feedback

Question 3

Accepted Answer

Epithelial tissue

Question 4

Which of the following is NOT a function of the integumentary system?

Accepted Answer

Production of red blood cells

Question 5

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

Accepted Answer

Osteoclast

Question 6

A long bone grows in length at the:

Accepted Answer

Epiphyseal plate

Question 7

Which of the following equations correctly represents the calculation of the resting membrane potential ($$V_m) $$using the Nernst equation for potassium ions ($$K^+$$)?

Accepted Answer

$$V_m = \frac{RT}{zF} \ln \left( \frac{[K^+]_{out}}{[K^+]_{in}} \right)$$

Question 8

Which of the following best describes the difference between endocrine and exocrine glands?

Accepted Answer

Endocrine glands secrete hormones directly into the bloodstream; exocrine glands secrete products onto body surfaces or into body cavities.

Question 9

A patient is unable to abduct their arm at the shoulder joint. Which type of synovial joint is most likely affected?

Accepted Answer

Ball-and-socket joint

Question 10

Which of the following is a correct sequence of events in the sliding filament model of muscle contraction?

Accepted Answer

Calcium binds to troponin → Tropomyosin moves → Myosin binds to actin → Power stroke

Question 11

Which of the following best describes saltatory conduction in neurons?

Accepted Answer

Action potentials jump from one node of Ranvier to the next, increasing conduction speed.

Question 12

Which of the following is a function of the parasympathetic division of the autonomic nervous system?

Accepted Answer

Stimulates digestion and decreases respiratory rate

Question 13

Which of the following is a characteristic of connective tissue?

Accepted Answer

Contains a large amount of extracellular matrix.

Question 14

Which of the following best describes the function of the cerebellum?

Accepted Answer

Coordinates voluntary muscle movements and balance

Question 15

A patient with damage to the occipital lobe of the brain would most likely experience problems with:

Accepted Answer

Vision

Question 16

Which of the following equations correctly represents the calculation of body mass index (BMI)?

Accepted Answer

$$BMI = \frac{weight\ (kg)}{[height\ (m)]^2}$$

Question 17

Which of the following is a function of the skeletal system?

Accepted Answer

Storage of minerals such as calcium and phosphorus

Question 18

Which of the following best describes the role of Schwann cells in the peripheral nervous system?

Accepted Answer

They produce myelin sheaths around peripheral axons.

Question 19

Which of the following is a correct description of the anatomical position?

Accepted Answer

Body is standing upright, facing forward, arms at sides, palms facing forward.

Question 20

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

Accepted Answer

Cartilage is avascular, so nutrients and cells required for repair must diffuse from surrounding tissues.
