,Chapter 1: Introduction to the Body
1. The study of the structure of the body and the relationships among its parts is called:
A. Physiology
B. Anatomy
C. Histology
D. Cytology
Answer: B. Anatomy
Rationale: Anatomy focuses on body structure, while physiology focuses on function.
2. The study of how the body functions is called:
A. Anatomy
B. Physiology
C. Pathology
D. Embryology
Answer: B. Physiology
Rationale: Physiology examines the functions of body parts and systems.
3. Which level of organization is the smallest living unit?
A. Tissue
B. Organ
C. Cell
D. Molecule
Answer: C. Cell
Rationale: The cell is the basic structural and functional unit of life.
4. Which sequence correctly lists levels of organization from simplest to most complex?
A. Cell, tissue, organ, organ system, organism
B. Tissue, cell, organ, organism, organ system
C. Organ, tissue, cell, organ system, organism
D. Molecule, organ, cell, tissue, organism
Answer: A. Cell, tissue, organ, organ system, organism
Rationale: Cells form tissues, tissues form organs, organs form systems, and systems
form the organism.
5. The maintenance of a relatively stable internal environment is called:
A. Metabolism
, B. Homeostasis
C. Differentiation
D. Adaptation
Answer: B. Homeostasis
Rationale: Homeostasis is the body’s ability to maintain stable internal conditions
despite external changes.
6. A feedback mechanism that reverses a change and brings the body back toward normal
is:
A. Positive feedback
B. Negative feedback
C. Feed-forward control
D. Homeostatic imbalance
Answer: B. Negative feedback
Rationale: Negative feedback opposes the initial change and restores homeostasis.
7. Which is an example of positive feedback?
A. Regulation of blood glucose
B. Childbirth contractions
C. Thermoregulation
D. Blood pressure regulation
Answer: B. Childbirth contractions
Rationale: Positive feedback amplifies a change; uterine contractions intensify until
birth.
8. In anatomical position, the body is:
A. Lying face down
B. Lying face up
C. Standing erect with arms at sides and palms forward
D. Sitting with legs crossed
Answer: C. Standing erect with arms at sides and palms forward
Rationale: Anatomical position is the standard reference for describing body directions.
9. The term that means toward the head or upper part of the body is:
A. Inferior
B. Superior
C. Anterior
D. Posterior
Answer: B. Superior
Rationale: Superior means above or toward the head.
, 10. The term that means toward the front of the body is:
A. Posterior
B. Anterior
C. Lateral
D. Medial
Answer: B. Anterior
Rationale: Anterior refers to the front or ventral side of the body.
11. A plane that divides the body into equal right and left halves is the:
A. Transverse plane
B. Frontal plane
C. Midsagittal plane
D. Oblique plane
Answer: C. Midsagittal plane
Rationale: A midsagittal plane runs vertically through the midline, creating equal right
and left halves.
12. The dorsal body cavity contains the:
A. Thoracic and abdominopelvic cavities
B. Cranial and spinal cavities
C. Abdominal and pelvic cavities
D. Mediastinal and pleural cavities
Answer: B. Cranial and spinal cavities
Rationale: The dorsal cavity includes the cranial cavity, which houses the brain, and the
spinal cavity, which houses the spinal cord.
13. The diaphragm separates the:
A. Thoracic cavity from the abdominopelvic cavity
B. Cranial cavity from the spinal cavity
C. Abdominal cavity from the pelvic cavity
D. Right and left pleural cavities
Answer: A. Thoracic cavity from the abdominopelvic cavity
Rationale: The diaphragm is a dome-shaped muscle that separates the thoracic and
abdominopelvic cavities.
14. The serous membrane that covers the lungs is the:
A. Pericardium
B. Peritoneum
C. Pleura
D. Meninges
