Question 1

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

Accepted Answer

Anatomy studies the structure of body parts, and physiology studies how those parts function together.

Question 2

A patient is experiencing a rapid drop in blood pressure. The body responds by increasing heart rate to restore normal pressure. Which type of feedback mechanism is this, and why?

Accepted Answer

Negative feedback, because it counteracts the original change to maintain homeostasis.

Question 3

Which of the following correctly lists the levels of structural organization in the human body from simplest to most complex?

Accepted Answer

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

Question 4

Which of the following best describes the anatomical position?

Accepted Answer

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

Question 5

A surgeon makes an incision that divides the body into anterior and posterior parts. Which anatomical plane is used?

Accepted Answer

Frontal (coronal) plane

Question 6

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

Accepted Answer

Blood clotting after a vessel injury

Question 7

Which directional term best describes the relationship of the heart to the lungs?

Accepted Answer

The heart is medial to the lungs.

Question 8

A patient has a stab wound that penetrates the parietal serosa of the pericardium. Which structure is directly deep to this layer?

Accepted Answer

Visceral serosa

Question 9

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

Accepted Answer

Question 10

A patient is experiencing homeostatic imbalance due to kidney failure. What is the simple term that describes this condition?

Question 12

Which body cavity contains the brain?

Accepted Answer

Question 13

Which of the following best describes the difference between visceral and parietal serosa?

Accepted Answer

Question 14

Which of the following is an example of manipulation as used in clinical anatomy?

Accepted Answer

Moving a joint to assess its range of motion

Question 15

Which pathway carries information from the receptor to the control center in a homeostatic mechanism?

Accepted Answer

Afferent pathway

Question 16

A cross-section through the body that divides it into superior and inferior parts is made along which plane?

Accepted Answer

Transverse plane

Question 17

Which of the following is a function of the synovial cavity?

Accepted Answer

Reduces friction between moving joints

Question 18

A patient is lying on their back with their palms facing upward. Which anatomical term best describes this position?

Accepted Answer

Supine

Question 19

Which of the following best explains why negative feedback is more common than positive feedback in the human body?

Accepted Answer

Negative feedback maintains stability by reversing deviations from a set point.

Question 20
