Hole's Essentials of Human Anatomy & Physiology (15th Edition) — Questions with
Detailed Rationales
Chapter 1: Introduction to Human Anatomy and Physiology (20 Questions)
1. The study of the structure of body parts and their relationships to one another is
called:
A) Physiology
B) Anatomy
C) Histology
D) Cytology
Rationale: Anatomy is the study of the structure of body parts and their relationships.
Physiology studies the functions of body parts. Histology studies tissues and cytology
studies cells.
2. The principle that states that function is determined by structure is known as:
A) Homeostasis
B) The complementarity of structure and function
C) The unity of form
D) The principle of physiology
, Page 2 of 74
Rationale: The principle of complementarity of structure and function states that what
a structure can do depends on its specific form.
3. The smallest unit of an element that retains the properties of that element is
a(n):
A) Molecule
B) Atom
C) Compound
D) Ion
Rationale: An atom is the smallest unit of an element that retains the properties of that
element.
4. Which of the following levels of structural organization is the most complex?
A) Cellular level
B) Tissue level
C) Organ level
D) Organism level
Rationale: The organism level is the most complex, composed of all organ systems
working together to maintain life.
5. The maintenance of a relatively stable internal environment despite external
changes is called:
A) Metabolism
B) Homeostasis
C) Adaptation
D) Responsiveness
Rationale: Homeostasis is the body's ability to maintain a relatively stable internal
environment despite external changes.

6. Which of the following is an example of a negative feedback mechanism?
A) Blood clotting
B) Childbirth
C) Regulation of blood glucose
D) Fever
Rationale: Blood glucose regulation counters deviations, making it a negative feedback
mechanism. Childbirth and blood clotting are positive feedback mechanisms.
7. The anatomical position is characterized by:
A) Palms facing posteriorly
B) Body erect, arms at sides, palms forward
C) Lying face down
D) Sitting upright
Rationale: In anatomical position, the body is erect, arms at the sides, and palms
facing anteriorly (forward).
8. The term that means "toward the head" is:
A) Caudal
B) Cephalic
C) Proximal
D) Distal
Rationale: Cephalic means toward the head; caudal means toward the feet; proximal
means near the source; distal means away from the source.
9. The plane that divides the body into equal right and left halves is the:
A) Transverse plane
B) Coronal plane
, Page 4 of 74
C) Midsagittal plane
D) Oblique plane
Rationale: The midsagittal plane divides the body into equal right and left halves.
10. The thoracic cavity is separated from the abdominopelvic cavity by the:
A) Mediastinum
B) Diaphragm
C) Pericardium
D) Pleura
Rationale: The diaphragm is the muscular sheet that separates the thoracic cavity from
the abdominopelvic cavity.
11. Which of the following is NOT one of the four primary tissue types?
A) Epithelial
B) Connective
C) Vascular
D) Nervous
Rationale: The four primary tissue types are epithelial, connective, muscle, and
nervous. Vascular is not a primary classification.
12. The study of the function of body parts is called:
A) Anatomy
B) Physiology
C) Histology
D) Embryology
Rationale: Physiology is the study of the functions of body parts, focusing on how they
work.
