Module 1
1. What is the study of the structure of the human body?
A) Anatomy
B) Physiology
C) Histology
D) Cytology
Correct Answer: A) Anatomy
Rationale: Anatomy is the study of the body’s structures and their relationships.
Physiology studies function, histology studies tissues, and cytology focuses on
cells. Structure determines function, making anatomy foundational.
2. The level of organization immediately above the cellular level is the:
A) Chemical level
B) Tissue level
C) Organ level
D) Organ system level
Correct Answer: B) Tissue level
,Rationale: The hierarchy progresses from chemical to cellular to tissue. Tissues
are groups of similar cells performing a common function. Organs are made of
multiple tissues, and organ systems consist of multiple organs.
3. The ventral body cavity contains which two subdivisions?
A) Cranial and vertebral
B) Dorsal and ventral
C) Thoracic and abdominopelvic
D) Pleural and pericardial
Correct Answer: C) Thoracic and abdominopelvic
Rationale: The ventral cavity is the anterior cavity, divided by the diaphragm
into the superior thoracic cavity (heart, lungs) and the inferior abdominopelvic
cavity (digestive, urinary, reproductive organs).
4. Which body system is primarily responsible for responsiveness to stimuli?
A) Muscular system
B) Integumentary system
C) Endocrine system
D) Nervous system
Correct Answer: D) Nervous system
Rationale: The nervous system detects changes in the internal and external
environment and initiates responses via electrical impulses. The muscular
, system produces movement; the endocrine system uses hormones; the
integumentary system protects.
5. The anatomical term “proximal” means:
A) Closer to the point of attachment
B) Farther from the point of attachment
C) Toward the midline
D) Away from the midline
Correct Answer: A) Closer to the point of attachment
Rationale: Proximal describes a position nearer the trunk or origin of a limb.
Distal means farther away. Medial and lateral refer to the midline, not
attachment points.
6. The frontal plane divides the body into:
A) Right and left portions
B) Superior and inferior portions
C) Anterior and posterior portions
D) Medial and lateral portions
Correct Answer: C) Anterior and posterior portions
Rationale: The frontal (coronal) plane runs vertically and separates the body
into front (anterior) and back (posterior) sections. The sagittal plane divides
right/left; transverse divides superior/inferior.
