Question 1

Which of the following best describes the principle of complementarity of structure and function?

Accepted Answer

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

Question 2

A patient is experiencing difficulty with blood glucose regulation. Which organ system is primarily responsible for this homeostatic control?

Accepted Answer

Endocrine system

Question 3

Which of the following is an example of a negative feedback mechanism in the human body?

Accepted Answer

Regulation of blood glucose by insulin

Question 4

A cut made along which anatomical plane would separate the body into anterior and posterior parts?

Accepted Answer

Frontal (coronal) plane

Question 5

Which of the following best describes the function of serous membranes in the ventral body cavity?

Accepted Answer

They secrete serous fluid to reduce friction between organs.

Question 6

A midsagittal section of the body would pass through which of the following structures?

Accepted Answer

Vertebral column

Question 7

Which of the following is the correct order of levels of structural organization in the human body, from simplest to most complex?

Accepted Answer

Chemical, cellular, tissue, organ, organ system, organismal

Question 8

A patient has a stab wound that penetrates the parietal pericardium. Which organ is at risk of direct injury?

Accepted Answer

Heart

Question 9

Which of the following best illustrates a positive feedback mechanism?

Accepted Answer

Enhancement of labor contractions by oxytocin

Question 10

If a patient is lying in the standard anatomical position, which of the following statements is true?

Accepted Answer

The body is erect, feet slightly apart, and palms facing forward with thumbs pointing away from the body.

Question 11

Which of the following best describes the function of the control center in a homeostatic control system?

Accepted Answer

It determines the set point at which a variable is maintained and determines the appropriate response.

Question 12

A cross section of the body is made at a 90° angle to the vertical plane. Which anatomical plane does this describe?

Accepted Answer

Transverse (horizontal) plane

Question 13

Which of the following is a correct pairing of a serous membrane and the organ it surrounds?

Accepted Answer

Peritoneum – abdominopelvic organs

Question 14

A patient is diagnosed with a disease that results from a homeostatic imbalance. Which of the following is a likely consequence if negative feedback mechanisms are overwhelmed?

Accepted Answer

Destructive positive feedback mechanisms may take over, leading to conditions such as heart failure.

Question 15

Which of the following best describes the role of effectors in a homeostatic control system?

Accepted Answer

They provide the means to respond to a stimulus, either reducing or enhancing the stimulus.

Question 16

A physician palpates the right lower quadrant (RLQ) of a patient’s abdomen. Which organ is most likely being examined?

Accepted Answer

Appendix

Question 17

Which of the following is an example of microscopic anatomy?

Accepted Answer

Observing the organization of cells in a tissue sample under a microscope

Question 18

Which of the following best describes the relationship between the axial and appendicular divisions of the body?

Accepted Answer

Axial includes the head, neck, and trunk; appendicular includes the limbs.

Question 19

A patient is experiencing pain in the left hypochondriac region. Which organ is most likely involved?

Accepted Answer

Spleen

Question 20

Which of the following best explains why the study of physiology often focuses on cellular and molecular levels?

Accepted Answer

Because the body's abilities are dependent on chemical reactions in individual cells.
