Chapter 1: Introduction to Human Anatomy and Physiology
Q1. The branch of science that deals with the structure of human
body parts is called:
A) Physiology
B) Anatomy
C) Histology
D) Cytology
Answer: B) Anatomy
Rationale: Anatomy is the study of the structure of body parts and their
relationships to one another. Physiology (A) is the study of function.
Histology (C) is the study of tissues, and cytology (D) is the study of cells,
both of which are subdivisions of anatomy .
Q2. An investigator who conducts an experiment to determine how
temperature changes affect the rate at which the heart beats is most
likely a(n):
A) Anatomist
B) Physiologist
C) Chemist
D) Biochemist
Answer: B) Physiologist
Rationale: Physiology deals with the functions of body parts—what they
do and how they do it. Studying how temperature affects heart rate is a
functional question, making this a physiological investigation .
Q3. The term "anatomy" is derived from Greek words meaning:
A) To study function
B) To cut apart
C) To examine tissues
D) To understand life
,Answer: B) To cut apart
Rationale: Anatomy comes from Greek words meaning "to cut apart."
Early anatomists gained knowledge by dissecting (cutting apart)
cadavers to observe internal structures .
Q4. Why are the topics of anatomy and physiology difficult to
separate?
A) Physiological functions depend on the anatomy of structures
B) They were discovered at the same time
C) The body parts take up space
D) Our understanding of physiology is changing more than our
understanding of anatomy
Answer: A) Physiological functions depend on the anatomy of structures
Rationale: Anatomy and physiology are inseparable because function
depends on structure. The structure of a body part determines what
functions it can perform .
Q5. Dissection of human bodies became part of formal medical
school coursework in which century?
A) 17th century
B) 18th century
C) 19th century
D) 20th century
Answer: C) 19th century
Rationale: Dissection of human bodies became part of formal medical
education in the 19th century, though anatomical study had been
occurring for centuries before this formalization .
Q6. Agriculture began in some countries as recently as how many
years ago?
A) 1,000 years
B) 5,000 years
C) 10,000 years
D) 50,000 years
Answer: C) 10,000 years
Rationale: The agricultural revolution began approximately 10,000 years
ago in some regions, transitioning human societies from hunter-gatherer
lifestyles to settled farming communities .
,Q7. Standing erect with face and palms forward and upper limbs at
the sides describes the _____ position.
A) Supine
B) Prone
C) Anatomical
D) Frontal
Answer: C) Anatomical
Rationale: The anatomical position is a standardized position used as a
reference point in anatomy. The body is erect, face forward, upper limbs
at the sides with palms facing forward .
Q8. Which of the following is the smallest living unit of structure in
the body?
A) Atom
B) Molecule
C) Cell
D) Tissue
Answer: C) Cell
Rationale: The cell is the smallest living unit of structure and function in
the body. Atoms and molecules are non-living chemical components.
Tissues are groups of cells .
Q9. The dorsal body cavity contains which of the following?
A) Thoracic and abdominopelvic cavities
B) Cranial and spinal cavities
C) Abdominal and pelvic cavities
D) Pleural and pericardial cavities
Answer: B) Cranial and spinal cavities
Rationale: The dorsal body cavity is located toward the back of the body
and includes the cranial cavity (brain) and the spinal (vertebral) cavity
(spinal cord). The ventral body cavity contains the thoracic and
abdominopelvic cavities .
Q10. The mediastinum is located in which cavity?
A) Abdominal cavity
B) Pelvic cavity
C) Thoracic cavity (between the lungs)
D) Cranial cavity
, Answer: C) Thoracic cavity (between the lungs)
Rationale: The mediastinum is the central compartment of the thoracic
cavity containing the heart, thymus, trachea, esophagus, and major
blood vessels .
Q11. Which membrane lines the thoracic cavity and covers the
lungs?
A) Pericardium
B) Pleura
C) Peritoneum
D) Mesentery
Answer: B) Pleura
Rationale: The pleura is the serous membrane that lines the thoracic
cavity (parietal pleura) and covers the lungs (visceral pleura). The
pericardium (A) covers the heart; the peritoneum (C) lines the
abdominopelvic cavity .
Q12. The heart is located in which body cavity?
A) Cranial cavity
B) Abdominal cavity
C) Pericardial cavity (within the thoracic cavity)
D) Pelvic cavity
Answer: C) Pericardial cavity (within the thoracic cavity)
Rationale: The pericardial cavity is a subdivision of the thoracic cavity
(specifically within the mediastinum) that contains the heart. The heart is
not in the abdominal or pelvic cavities .
Q13. The study of tissues is called:
A) Embryology
B) Histology
C) Cytology
D) Osteology
Answer: B) Histology
Rationale: Histology is the study of tissues. Cytology (C) is the study of
cells. Embryology (A) is the study of development before birth.
Osteology (D) is the study of bones .
