Question 1: A group of cells that work together to perform a particular
function is a(n) __?__.
1. molecule
2. tissue
3. organism
4. compound
5. organ
Correct Answer:
tissue
Explanation:
A tissue is a group of cells that work together to perform a particular function, such as muscle tissue or nerve tissue,
and is the most specific and accurate answer among the options.

Question 2: _____ feedback loops are more common in the body and are
better at maintaining homeostasis.

,1. positive
2. negative
Correct Answer:
negative
Explanation:
Negative feedback loops are more common in the body and are better at maintaining homeostasis because they help
to correct deviations from normal physiological levels, thereby stabilizing the internal environment.

Question 3: Which of the following is true of anatomy & physiology?
1. Anatomy is the study of the structure of the human body
2. Physiology is the study of the function of body systems
3. Structure determines function
4. None of the above are true
5. All of the above are true
Correct Answer:
Anatomy is the study of the structure of the human body
Explanation:
Anatomy is indeed the study of the structure of the human body, which is a fundamental concept in the field of
anatomy and physiology.

Question 4: What anatomical term describes a position closer to the
midline of the body?
1. Lateral
2. Medial
3. Distal
4. Proximal
Correct Answer:
Medial
Explanation:
Medial refers to a position closer to the midline of the body, as opposed to lateral which refers to a position farther
away from the midline.

Question 5: Toward the head is referred to as:
1. Superior
2. Superficial
3. Ventral
4. Deep
Correct Answer:
Superior
Explanation:
The term "superior" refers to the direction towards the head or upper part of the body, making it the most likely
correct answer.

,Question 6: In humans, the term 'dorsal' can be used interchangeably
with which of the following?
1. Anterior
2. Distal
3. Posterior
4. Inferior
Correct Answer:
Posterior
Explanation:
The term "dorsal" refers to the back or posterior region of the body, making option 3 "Posterior" the most likely correct
answer.

Question 7: Which component of a feedback loop acts to restore the
regulated variable to its set point?
1. the sensor
2. the control center
3. the effector
4. the stimulus
Correct Answer:
the effector
Explanation:
The effector is the component of a feedback loop that acts to restore the regulated variable to its set point by making
changes to the system, such as increasing or decreasing the output.

Question 8: Which of the following is NOT a subdivision of the thoracic
cavity?
1. left pleural division
2. right pleural division
3. medial pleural division
4. mediastium
Correct Answer:
medial pleural division
Explanation:
There is no such thing as a "medial pleural division", as the pleura is divided into two main parts: the left and right
pleural divisions, which surround the lungs and line the thoracic cavity.

Question 9: Posterior is to dorsal as anterior is to?
1. coronal
2. inferior
3. ventral
4. distal
Correct Answer:

, ventral
Explanation:
The correct analogy is that posterior refers to the back or rear, and dorsal refers to the back or upper surface of the
body, so anterior is paired with ventral, which refers to the front or lower surface of the body.

Question 10: The levels of organization from most simple to most
complex are:
1. Cell, chemical, organ, tissue, system
2. Tissue, cell, chemical, organ, system
3. Chemical, tissue, cell, organ, system
4. Chemical, cell, tissue, organ, system
Correct Answer:
Cell, chemical, organ, tissue, system
Explanation:
This is the correct answer because it lists the levels of organization from most simple to most complex, starting with
the chemical level, which is the most basic, and ending with the system level, which is the most complex.

Question 11: The body section that divides the nose from the back of the
head is a section.
1. frontal
2. temporal
3. sagittal
4. parietal
Correct Answer:
sagittal
Explanation:
The sagittal suture is the section that divides the nose from the back of the head, as it runs along the midline of the
skull, separating the frontal and occipital bones.

Question 12: In the context of human anatomy, which term is
synonymous with ventral when referring to the front of the body?
1. dorsal
2. superior
3. anterior
4. inferior
Correct Answer:
anterior
Explanation:
Anterior is the term synonymous with ventral when referring to the front of the body, as it refers to the direction
towards the front or forward part of the body.

Question 13: Which muscle serves as the primary separator between the
thoracic cavity and the abdominal cavity?
1. Intercostal muscles
