SECTION A: LEVELS OF ORGANIZATION & ANATOMICAL TERMINOLOGY
1. What is the smallest level of organization in the body that contains the body's
genetic information?
A. Chemical
B. Cellular
C. Tissue
1|Page
,D. Organism
Correct Answer: B
Rationale: The cellular level includes the nucleus, an organelle that contains
the body's genetic information (DNA). The chemical level is atoms and
molecules, which do not contain genetic information on their own.
2. The study of the external form of the body and its relationship to deeper
structures is called:
A. Systemic anatomy
B. Regional anatomy
C. Molecular biology
D. Microbiology
E. Surface anatomy
Correct Answer: E
Rationale: Surface anatomy is the study of the external form of the body and
its relationship to deeper structures. It is used to locate internal
structures based on external landmarks.
3."Cutting off your nose" would be a section in the _____ plane.
A. Coronal
B. Nasal
C. Median
2|Page
,D. Transverse
E. Sagittal
Correct Answer: A
Rationale: A coronal (frontal) plane divides the body into anterior and
posterior portions. Cutting off the nose would involve a coronal section
separating the front of the face from the back.
4. Which of the following is arranged in correct order from the simplest to most
complex level of organization?
A. Cellular, tissue, molecular, system, organ, organism
B. Molecular, cellular, tissue, organ, system, organism
C. Tissue, cellular, molecular, organ, system, organism
D. Organ, tissue, cellular, molecular, system, organism
Correct Answer: B
Rationale: The correct order from simplest to most complex is: chemical
(molecular), cellular, tissue, organ, organ system, organism.
5. A tissue is a:
A. Small structure within a cell
B. Group of cells with similar structure and function
C. Structure composed of multiple organs
D. The simplest level of organization
3|Page
, Correct Answer: B
Rationale: A tissue is defined as a group of similar cells that perform a
specific function. Examples include epithelial, connective, muscle, and
nervous tissue.
6. Which organ system is responsible for protecting the body from the external
environment and helping regulate body temperature?
A. Muscular system
B. Skeletal system
C. Integumentary system
D. Nervous system
Correct Answer: C
Rationale: The integumentary system (skin, hair, nails, glands) provides
protection from the external environment and helps regulate body
temperature through sweating and blood vessel dilation/constriction.
7. The term "proximal" means:
A. Farther from the point of attachment
B. Closer to the point of attachment
C. Toward the midline
D. Away from the midline
Correct Answer: B
