Question 1

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

Accepted Answer

Anatomy studies the structure of body parts, while physiology studies their function.

Question 2

A patient is experiencing a drop in blood glucose levels. The pancreas detects this change and releases glucagon, which causes the liver to release glucose into the blood, restoring normal levels. Which type of feedback mechanism is illustrated in this scenario?

Accepted Answer

Negative feedback

Question 3

Which of the following is the correct order of components in a typical homeostatic control system?

Accepted Answer

Stimulus → Receptor → Control center → Effector → Response

Question 4

Which directional term would best describe the relationship of the heart to the lungs?

Accepted Answer

Medial

Question 5

A surgeon makes a cut that separates the body into anterior and posterior portions. Which plane was used?

Accepted Answer

Coronal (frontal) plane

Question 6

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

Accepted Answer

Passive transport does not require energy, while active transport requires ATP.

Question 7

Which of the following is an example of a serous membrane?

Accepted Answer

Pericardium

Question 8

Which cellular adhesion is primarily responsible for preventing substances from passing between adjacent epithelial cells in the small intestine?

Accepted Answer

Tight junctions

Question 9

A neurotransmitter binds to a receptor on a postsynaptic cell, causing an immediate response. This is an example of which type of cellular receptor?

Accepted Answer

Ion channel-linked receptor

Question 10

Which of the following best describes the difference between intracellular and extracellular fluid?

Accepted Answer

Intracellular fluid is found inside cells, while extracellular fluid is found outside cells.

Question 11

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

Accepted Answer

It contains abundant extracellular matrix.

Question 12

A gland that releases its product by exocytosis without losing any part of the cell is classified as which type of gland?

Accepted Answer

Merocrine gland

Question 13

Which of the following best explains why connective tissue differs from epithelial tissue?

Accepted Answer

Connective tissue has more extracellular matrix than epithelial tissue.

Question 14

Which of the following is a correct example of directional terminology?

Accepted Answer

The stomach is inferior to the heart.

Question 15

A patient suffers a deep cut on the anterior surface of the forearm. Which body region is affected?

Accepted Answer

Antebrachial region

Question 16

Which of the following best describes the function of desmosomes?

Accepted Answer

They provide strong adhesion between cells, especially in tissues subject to mechanical stress.

Question 17

Which of the following statements about the dorsal and ventral body cavities is correct?

Accepted Answer

The dorsal cavity contains the brain and spinal cord, while the ventral cavity contains the thoracic and abdominopelvic organs.

Question 18

Which of the following is a function of the serous membranes?

Accepted Answer

They reduce friction between organs within the ventral body cavity.

Question 19

A patient is diagnosed with a disease that affects the extracellular matrix of connective tissue. Which of the following symptoms would most likely be observed?

Accepted Answer

Decreased structural support and increased tissue fragility

Question 20

Which of the following best describes the process of tissue repair after injury?

Accepted Answer
