Anatomy and Physiology: The Unity of Form and Function (10th Edition, Saladin) —
SECTION 1: ORGANIZATION OF THE BODY (40 Questions)
Chapter 1: Major Themes of Anatomy and Physiology (12 Questions)
1. The study of the structure of the human body and the relationships among its
parts is called:
A) Physiology
B) Anatomy
C) Histology
D) Cytology
Rationale: Anatomy is the study of body structure and the relationships among body
parts. Physiology studies function. Histology studies tissues, and cytology studies cells.
2. The principle of "unity of form and function" means:
A) All body systems work independently
B) Structure determines function
C) Function determines structure only
D) Anatomy is unrelated to physiology
Rationale: The principle of complementarity states that structure and function are
inseparably linked—what a structure can do depends on its specific form.

3. Homeostasis is best defined as:
A) Constant body temperature
B) Stable internal environment despite external change
C) Disease prevention
D) Cell division
Rationale: Homeostasis is the body's ability to maintain a relatively stable internal
environment despite external changes. It is a dynamic equilibrium, not a constant state.
4. Negative feedback mechanisms:
A) Increase the original stimulus
B) Maintain stability by reversing change
C) Are harmful
D) Occur only in disease
Rationale: Negative feedback mechanisms restore normal conditions by reversing the
direction of the initial stimulus. This is the most common homeostatic control
mechanism.
5. Which of the following is an example of negative feedback?
A) Blood clotting
B) Childbirth
C) Regulation of blood glucose
D) Fever
Rationale: Blood glucose regulation counters deviations—when glucose rises, insulin
lowers it; when glucose falls, glucagon raises it. Childbirth and blood clotting are
examples of positive feedback.

6. Positive feedback differs from negative feedback because positive feedback:
A) Stabilizes the body
B) Reverses change
C) Amplifies the initial stimulus
D) Maintains equilibrium
Rationale: Positive feedback amplifies the initial stimulus until a specific end point is
reached. It is less common than negative feedback and is involved in processes like
childbirth and blood clotting.
7. The levels of structural organization, from simplest to most complex, are:
A) Cell → molecule → tissue → organ → system → organism
B) Molecule → cell → tissue → organ → system → organism
C) Tissue → cell → organ → system → organism
D) Organ → tissue → cell → molecule
Rationale: The correct sequence is: chemical (molecule) → cellular → tissue → organ →
organ system → organism. This reflects increasing complexity.
8. The anatomical position includes:
A) Palms facing backward
B) Arms at sides, palms forward
C) Sitting posture
D) Supine position
Rationale: In anatomical position, the body is upright, arms at the sides, palms facing
anteriorly (forward), and feet flat on the floor.
9. Which of the following is NOT one of the four primary tissue types?
A) Epithelial
B) Connective
, Page 4 of 75
C) Vascular
D) Nervous
Rationale: The four primary tissue types are epithelial, connective, muscle, and
nervous. Vascular tissue is not a primary classification.
10. The study of the mechanism of disease is called:
A) Neuroanatomy
B) Neurophysiology
C) Pathophysiology
D) Histology
Rationale: Pathophysiology is the study of functional changes in the body as a result of
disease or injury, bridging pathology and physiology.
11. Which imaging technique is best for routinely examining the anatomical
development of a fetus?
A) Auscultation
B) PET scan
C) MRI
D) Sonography
Rationale: Sonography (ultrasound) uses high-frequency sound waves, is safe,
noninvasive, and uses no ionizing radiation, making it ideal for fetal assessment.
12. Andreas Vesalius is known as:
A) The father of modern anatomy
B) The discoverer of blood circulation
C) The founder of histology
D) The inventor of the microscope
