Question 1

Which of the following best describes the relationship between anatomy and physiology?

Accepted Answer

Anatomy is the study of structure, and physiology is the study of function; structure determines function.

Question 2

Which of the following is an example of a negative feedback loop in human physiology?

Accepted Answer

Sweating to reduce body temperature when overheated.

Question 3

A patient is experiencing a dangerously high fever that continues to rise. Which feedback mechanism is most likely responsible for this situation?

Accepted Answer

Positive feedback, which amplifies the rise in body temperature.

Question 4

Which of the following is NOT a characteristic of living things?

Accepted Answer

Random molecular turnover

Question 5

Which anatomical plane divides the body into anterior and posterior portions?

Accepted Answer

Coronal (frontal) plane

Question 6

A tissue sample is thinly sliced and stained for microscopic examination to diagnose disease. Which subfield of anatomy does this represent?

Accepted Answer

Histology

Question 7

Which of the following best explains why homeostasis is considered a dynamic equilibrium?

Accepted Answer

Physiological values fluctuate slightly around a set point, rather than remaining fixed.

Question 8

Which organ system is primarily responsible for transporting oxygen and nutrients throughout the body?

Accepted Answer

Circulatory system

Question 9

A scientist is studying the heart, blood vessels, and blood as a group. Which approach to anatomy is being used?

Accepted Answer

Systemic anatomy

Question 10

Which of the following best describes the role of the effector in a feedback loop?

Accepted Answer

It carries out the response to restore homeostasis.

Question 11

Which directional term describes a structure that is farther from the point of attachment or origin?

Accepted Answer

Distal

Question 12

Which of the following is an example of differentiation during development?

Accepted Answer

Mesoderm transforming into muscle, bone, cartilage, and blood.

Question 13

Which of the following is the correct order of levels of human complexity from largest to smallest?

Accepted Answer

Organism, organ system, organ, tissue, cell, organelle, molecule, atom

Question 14

A patient presents with a loss of homeostatic control of blood glucose. Which condition is most likely to result?

Accepted Answer

Diabetes mellitus

Question 15

Which of the following best describes the function of the integrating (control) center in a feedback loop?

Accepted Answer

It processes information and makes a response decision.

Question 16

Which of the following is a reason why precision is important in the use of medical terminology?

Accepted Answer

It ensures clear communication and reduces the risk of medical errors.

Question 17

Which of the following is an example of surface anatomy?

Accepted Answer

Studying the external features of the body by observation or palpation.

Question 18

Which term refers to the ability of organisms to sense and react to stimuli?

Accepted Answer

Excitability (Responsiveness)

Question 19

Which of the following is a correct example of a plural medical term?

Accepted Answer

Cortices

Question 20

A medical imaging method is needed to examine the internal structure of a living patient without dissection. Which principle is most relevant?

Accepted Answer

Medical imaging
