Question 1

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

Accepted Answer

Anatomy focuses on the structure of body parts, while physiology focuses on how those parts work.

Question 2

A patient is experiencing a drop in blood pressure. Which feedback mechanism is most likely to restore homeostasis?

Accepted Answer

Negative feedback, which will increase blood pressure back to normal.

Question 3

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

Accepted Answer

Release of oxytocin during childbirth to intensify uterine contractions.

Question 4

Which directional term describes a structure that is closer to the head than another structure?

Accepted Answer

Superior

Question 5

If a surgeon makes a cut that divides the body into right and left portions, which plane is being used?

Accepted Answer

Sagittal plane

Question 6

Which serous membrane directly covers the lungs?

Accepted Answer

Visceral pleura

Question 7

Which of the following best describes the difference between passive and active transport across a cell membrane?

Accepted Answer

Passive transport moves substances down their concentration gradient without energy input, while active transport requires energy to move substances against the gradient.

Question 8

Which cellular adhesion is most important for preventing cells from being pulled apart under mechanical stress?

Accepted Answer

Desmosomes

Question 9

Which type of epithelial tissue is best suited for diffusion and is found lining the air sacs of the lungs?

Accepted Answer

Simple squamous epithelium

Question 10

Which of the following is a characteristic of connective tissue that distinguishes it from epithelial tissue?

Accepted Answer

Connective tissue has abundant extracellular matrix and supports, binds, or protects other tissues.

Question 11

A patient suffers a deep cut on the forearm. Which tissue type is primarily responsible for rapid repair and regeneration of the skin?

Accepted Answer

Epithelial tissue

Question 12

Which of the following cellular receptors is responsible for rapid communication between adjacent cells in cardiac muscle?

Accepted Answer

Gap junctions

Question 13

Which body cavity contains the heart and is surrounded by the pericardial serous membrane?

Accepted Answer

Pericardial cavity

Question 14

Which of the following best describes the function of serous membranes?

Accepted Answer

They produce a lubricating fluid to reduce friction between organs.

Question 15

A researcher is studying the movement of glucose into a cell. Which equation best describes the rate of diffusion according to Fick's Law?

Accepted Answer

$J = -D \frac{dC}{dx}$

Question 16

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

Accepted Answer

Transmission of electrical impulses

Question 17

Which type of connective tissue is found in tendons and is specialized for resisting tension in one direction?

Accepted Answer

Dense regular connective tissue

Question 18

A patient is unable to absorb nutrients properly due to damage in the lining of the small intestine. Which type of epithelial tissue is most likely affected?

Accepted Answer

Simple columnar epithelium

Question 19

Which of the following best explains why the peritoneum is important in abdominal surgery?

Accepted Answer

It produces serous fluid to reduce friction and prevent adhesions between abdominal organs.

Question 20

Which of the following best describes the process of signal transduction in cellular receptors?

Accepted Answer

It is the conversion of an extracellular signal into a specific cellular response.
