,Complete Test Bank for Structure & Function of the Body, 16th
Edition - Patton & Thibodeau (All 22 Chapters
Question 1
What is the anatomical term for the study of the function of living
organisms and their parts?
• A. Anatomy
• B. Physiology
• C. Pathology
• D. Histology
Correct Answer: B. Physiology
Detailed Rationale: Physiology is the science that deals with the
functions and activities of living organisms and their parts, whereas
anatomy focuses on the structural organization of body parts.
Question 2
Which plane divides the body into right and left equal halves?
• A. Frontal plane
• B. Transverse plane
• C. Midsagittal (median) plane
• D. Oblique plane
Correct Answer: C. Midsagittal (median) plane
,Detailed Rationale: The midsagittal plane passes lengthwise through
the midline, dividing the body or organ into equal right and left halves.
Question 3
What feedback mechanism amplifies or reinforces the change that is
occurring in the body's physiological state?
• A. Negative feedback control
• B. Positive feedback control
• C. Homeostatic stabilization
• D. Equilibrium arrest
Correct Answer: B. Positive feedback control
Detailed Rationale: Positive feedback loops amplify or accelerate the
change (e.g., uterine contractions during labor or blood clotting),
moving the system further away from its initial set point temporarily.
Question 4
Which body cavity contains the thoracic and abdominopelvic cavities?
• A. Dorsal cavity
• B. Cranial cavity
• C. Ventral cavity
• D. Spinal cavity
Correct Answer: C. Ventral cavity
Detailed Rationale: The ventral cavity is a large anterior cavity that is
subdivided by the diaphragm into the superior thoracic cavity and the
inferior abdominopelvic cavity.
, Question 5
What is the basic chemical unit of matter that cannot be broken down
into simpler substances by ordinary chemical means?
• A. Compound
• B. Molecule
• C. Element
• D. Electron
Correct Answer: C. Element
Detailed Rationale: An element is a pure substance made up of only
one kind of atom that cannot be broken down chemically into simpler
substances.
Question 6
Which subatomic particles carry a positive charge and are found in the
nucleus of an atom?
• A. Electrons
• B. Neutrons
• C. Protons
• D. Positrons
Correct Answer: C. Protons
Detailed Rationale: Protons are positively charged subatomic particles
located within the atomic nucleus, whereas neutrons have no charge,
and electrons are negatively charged and orbit the nucleus.
