Question 1

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

Accepted Answer

Anatomy is the study of structure, and physiology is the study of function; structure determines function.

Question 2

A patient is unable to maintain a stable internal body temperature after suffering a head injury. Which component of the homeostatic control system is most likely impaired?

Accepted Answer

Control center

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 person is exposed to a cold environment, causing their body temperature to drop. Which of the following best describes the sequence of events in the homeostatic response?

Accepted Answer

Receptor detects the change, control center processes information, effector initiates response

Question 5

Which of the following best illustrates the concept of 'structure determines function'?

Accepted Answer

The heart's muscular walls allow it to pump blood throughout the body.

Question 6

Which of the following is NOT considered a necessary life function?

Accepted Answer

Photosynthesis

Question 7

A patient with severe dehydration is at risk because water is essential for which of the following reasons?

Accepted Answer

Water is required for chemical reactions and makes up about 60-80% of body weight.

Question 8

Which of the following best describes the anatomical position?

Accepted Answer

Standing upright, facing forward, arms at sides, palms facing forward

Question 9

A surgeon makes a cut that divides the body into anterior and posterior parts. Which plane is this?

Accepted Answer

Frontal (coronal)

Question 10

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

Accepted Answer

Executes the response to restore homeostasis

Question 11

A patient has a tumor in the mediastinum. Which of the following organs could be affected?

Accepted Answer

Heart

Question 12

Which of the following is a correct pairing of a body cavity and the membrane that lines it?

Accepted Answer

Pericardial cavity lined by parietal pericardium

Question 13

Which of the following best explains why oxygen is a survival need for humans?

Accepted Answer

Oxygen is required for chemical reactions that release energy from food.

Question 14

A patient is experiencing a disturbance in homeostasis resulting in disease. Which of the following could be a possible cause?

Accepted Answer

All of the above

Question 15

Which of the following best describes a positive feedback mechanism?

Accepted Answer

It amplifies the original stimulus, moving the variable farther from the set point.

Question 16

A patient is unable to absorb nutrients properly due to a malfunction in the breakdown and absorption of food. Which necessary life function is most directly affected?

Accepted Answer

Digestion

Question 17

Which of the following best describes the difference between gross (macroscopic) and microscopic anatomy?

Accepted Answer

Gross anatomy studies large structures visible to the naked eye; microscopic anatomy studies structures only visible with a microscope.

Question 18

A patient has a wound on the anterior side of the forearm. Which directional term best describes the location of the wound relative to the elbow?

Accepted Answer

Distal

Question 19

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

Accepted Answer

Detects changes in the environment and sends information to the control center

Question 20

A patient is unable to eliminate metabolic wastes from the body. Which necessary life function is most directly impaired?

Accepted Answer

Excretion
