Auscultation

Question 3

Which of the following is a subdiscipline of physiology that focuses on the mechanisms of disease?

Accepted Answer

Pathophysiology

Question 4

Which historical figure is credited with establishing a code of ethics for physicians and encouraging the search for natural causes of disease?

Accepted Answer

Hippocrates

Question 5

Which imaging technique is best for visualizing soft tissues and does not expose the patient to X-rays?

Question 8

Which statement about anatomical variation among humans is correct?

Accepted Answer

Some individuals may have an atypical number of vertebrae or organs.

Question 9

Which of the following best describes the scientific method's hypothetico-deductive approach?

Accepted Answer

Formulating a testable hypothesis and designing experiments to test it.

Question 10

Which adaptation is shared by primates and is thought to have evolved due to tree-dwelling habits?

Accepted Answer

Opposable thumbs and prehensile hands

Question 11

Which of the following is a correct sequence in the hierarchy of human structural complexity, from largest to smallest?

Accepted Answer

Organism → Organ system → Organ → Tissue → Cell → Organelle → Molecule → Atom

Question 12

A patient is given a placebo in a clinical trial. What is the primary purpose of the placebo?

Accepted Answer

Question 13

Which of the following is an example of positive feedback in human physiology?

Accepted Answer

Question 18

Which scientist is credited with first observing and naming 'cells' using a compound microscope?

Accepted Answer

Robert Hooke

Question 19

Which of the following best describes the cell theory?
