Chapter 1: Introduction to the Body (1–10)
1. The study of the structure of the human body is called:
A. Physiology
B. Homeostasis
C. Anatomy
D. Histology
Answer: C. Anatomy
Rationale: Anatomy is the study of structure; physiology is the study of function.
Histology is the study of tissues.
2. The correct sequence of the levels of organization from simplest to most
complex is:
A. Cellular, chemical, tissue, organ
,B. Chemical, cellular, tissue, organ, system
C. Chemical, tissue, cellular, organ, system
D. Cellular, tissue, chemical, organ, system
Answer: B. Chemical, cellular, tissue, organ, system
Rationale: This hierarchical order reflects increasing complexity: atoms/molecules
→ cells → tissues → organs → organ systems → organism.
3. The reference position for all body directional terms is the:
A. Prone position
B. Supine position
C. Anatomical position
D. Fowler's position
Answer: C. Anatomical position
Rationale: Anatomical position is standing upright, facing forward, arms at sides
with palms forward, feet parallel. All directional terms are based on this
reference.
,4. The heart is ______ to the lungs.
A. Lateral
B. Distal
C. Medial
D. Superior
Answer: C. Medial
Rationale: Medial means toward the midline. The heart lies between the lungs,
closer to the body's midline than either lung.
5. Toward the head is referred to as:
A. Inferior
B. Cranial (superior)
C. Caudal
D. Ventral
Answer: B. Cranial (superior)
, Rationale: Cranial means toward the head; caudal means toward the tailbone.
Superior is the directional equivalent in human anatomy.
6. The plane that divides the body into equal right and left halves is the:
A. Frontal plane
B. Transverse plane
C. Sagittal plane
D. Midsagittal (median) plane
Answer: D. Midsagittal (median) plane
Rationale: The midsagittal plane runs exactly down the midline, creating equal
right and left halves. Other sagittal planes are offset.
7. The dorsal body cavity contains the:
A. Heart and lungs
B. Brain and spinal cord
C. Digestive organs
D. Reproductive organs
