Question 2

A patient is lying face up on an examination table with arms at their sides and palms facing upward. Which anatomical term best describes this position?

Accepted Answer

Supine

Question 3

Which of the following is an example of the relationship between structure and function at the gross anatomy level?

Accepted Answer

The elbow joint allows movement in one plane because of its hinge-like structure.

Question 4

Which of the following is NOT a characteristic shared by all living things?

Accepted Answer

Ability to photosynthesize

Question 5

Which of the following best describes the principle of homeostasis?

Accepted Answer

The body maintains a stable internal environment within a normal range around a set point.

Question 6

A patient has a disorder that prevents their sweat glands from functioning. Which homeostatic mechanism is most directly affected?

Accepted Answer

Negative feedback regulation of body temperature

Question 7

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

Accepted Answer

Atom, molecule, cell, tissue, organ, organ system, organism

Question 8

Which of the following best describes the function of epithelial tissue?

Accepted Answer

Forms barriers and covers exposed surfaces

Question 9

A patient is experiencing difficulty with blood transport and nutrient delivery throughout their body. Which organ system is most likely affected?

Accepted Answer

Cardiovascular system

Question 10

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

Accepted Answer

Sweating to reduce body temperature when overheated

Question 11

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

Accepted Answer

Medial

Question 12

A surgeon makes an incision just inferior to the diaphragm. Which body cavity is opened?

Accepted Answer

Abdominopelvic cavity

Question 13

Which of the following best explains why most physiological values are listed as ranges rather than averages?

Accepted Answer

Because homeostatic regulation allows for small fluctuations around a set point

Question 14

Which of the following is NOT a function of the integumentary system?

Accepted Answer

Production of blood cells

Question 15

Which of the following best describes the role of the control center in a homeostatic regulatory mechanism?

Accepted Answer

It processes information from the receptor and sends commands to the effector.

Question 16

Which sectional plane would separate the two eyes?

Accepted Answer

Sagittal plane

Question 17

Which of the following is a function of connective tissue?

Accepted Answer

Providing support and structure to the body

Question 18

Which organ system is primarily responsible for defending the body against infection and returning tissue fluid to the bloodstream?

Accepted Answer

Lymphatic system

Question 19

A patient with a spinal cord injury is unable to move their legs. Which two organ systems are most directly involved in this loss of function?

Accepted Answer

Muscular and nervous systems

Question 20

Which of the following best explains why positive feedback is helpful in blood clotting but unsuitable for regulating body temperature?

Accepted Answer

Positive feedback is only used for processes that must be completed quickly, while body temperature requires stable regulation.
