Question 1

Which of the following best describes the principle of 'complementarity of structure and function' in anatomy and physiology?

Accepted Answer

The structure of a body part is directly related to its specific function, and function can influence structure.

Question 2

Which of the following is NOT one of the necessary life functions listed in the study materials?

Accepted Answer

Ability to reproduce offspring

Question 3

A patient is unable to maintain a stable internal body temperature despite changes in the external environment. Which concept does this scenario best illustrate?

Accepted Answer

Homeostatic imbalance

Question 4

Which of the following is the correct sequence of the three components involved in homeostatic control of variables?

Accepted Answer

Receptor, control center, effector

Question 5

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

Accepted Answer

Regulation of blood glucose levels by insulin

Question 6

Which of the following best describes the function of the muscular system as listed in the study materials?

Accepted Answer

Allows manipulation of the environment, locomotion, and facial expression

Question 7

Which of the following is NOT a survival need for humans according to the study materials?

Accepted Answer

Nitrogen

Question 8

If a person’s plasma membranes fail to separate cells from their environment, which necessary life function is directly compromised?

Accepted Answer

Separation of internal and external environments

Question 9

Which subdivision of anatomy focuses on the study of large, visible structures?

Accepted Answer

Gross anatomy

Question 10

Which of the following is a correct statement about organ systems?

Accepted Answer

Organ systems consist of organs that work closely together to perform specific functions.

Question 11

Which of the following is the most abundant chemical in the body and provides the watery environment needed for chemical reactions?

Accepted Answer

Water

Question 12

Which level of structural organization is defined by a group of similar cells performing a common function?

Accepted Answer

Tissue level

Question 13

Which of the following is NOT one of the four basic tissue types?

Accepted Answer

Adipose tissue

Question 14

A scientist is studying the microscopic structure of liver cells. Which subdivision of anatomy is she using?

Accepted Answer

Histology

Question 15

Which of the following equations best represents the sum of all chemical reactions in body cells?

Accepted Answer

$$\sum_{i=1}^{n} R_i$$

Question 16

Which of the following is a function of the plasma membrane as described in the study materials?

Accepted Answer

It separates the organism from its environment.

Question 17

Which of the following best describes the role of the control center in homeostatic regulation?

Accepted Answer

It determines the set point at which the variable is maintained and processes input from the receptor.

Question 18

Which of the following is an example of a positive feedback mechanism?

Accepted Answer

Enhancement of labor contractions by oxytocin

Question 19

If the body’s negative feedback mechanisms become overwhelmed, what is most likely to occur?

Accepted Answer

Destructive positive feedback mechanisms may take over, leading to disease.

Question 20

Which of the following best describes the afferent pathway in a homeostatic control system?

Accepted Answer

It carries information from the receptor to the control center.
