1. Which of the following best describes the study of the structure and shape of the body and its parts?
A) Physiology
B) Anatomy
C) Cytology
D) Histology
Correct Answer: Anatomy
Rationale: Anatomy is the study of the structure and shape of the body and its parts, while physiology is
the study of how the body and its parts function. Cytology is the study of cells, and histology is the study
of tissues.
2. What is the primary function of the integumentary system in maintaining homeostasis?
A) Movement of the body
B) Digestion of nutrients
C) Protection of internal environment from external environment
D) Responsiveness to stimuli
Correct Answer: Protection of internal environment from external environment
Rationale: The integumentary system provides the necessary life function that protects our internal
environment from our external environment. The muscular system provides movement, and the
nervous system provides responsiveness.
3. In the standard anatomical position, how are the palms of the hands oriented?
A) Facing posteriorly
B) Facing anteriorly
,C) Facing medially
D) Facing laterally
Correct Answer: Facing anteriorly
Rationale: In the anatomical position, the body is standing erect, facing forward, with arms at the sides
and palms facing forward (anteriorly). This provides a standard reference point for describing body
parts.
4. Which type of tissue covers the body surface and lines the cavities of the body?
A) Muscle tissue
B) Nervous tissue
C) Connective tissue
D) Epithelial tissue
Correct Answer: Epithelial tissue
Rationale: Epithelial tissue covers the body surface and lines the cavities of the body. It performs
functions of protecting, absorbing, and secreting substances.
5. According to the levels of structural organization, which level comes immediately after the cellular
level?
A) Chemical
B) Tissue
C) Organ
D) Organ system
Correct Answer: Tissue
, Rationale: The six levels of organization in the body are: chemical, cellular, tissue, organ, organ system,
and organism. Therefore, the tissue level comes immediately after the cellular level.
6. What is the primary purpose of adenosine triphosphate (ATP) in the body?
A) To store genetic information
B) To provide energy for cellular activities
C) To build new proteins
D) To transport oxygen in the blood
Correct Answer: To provide energy for cellular activities
Rationale: ATP is an energy-rich molecule that powers cellular activities. It is the primary energy
currency of the cell, used to drive endergonic reactions.
7. Which organ system is primarily responsible for the function of movement?
A) Nervous system
B) Skeletal system
C) Muscular system
D) Integumentary system
Correct Answer: Muscular system
Rationale: The muscular system is the system that helps provide movement. The nervous system
provides responsiveness, and the skeletal system provides support and protection.
8. What is the name of the plane that divides the body into superior and inferior portions?
A) Sagittal plane
B) Frontal plane
C) Transverse plane
D) Midsagittal plane
