CHAPTER 1: ORIENTATION TO THE HUMAN BODY
1. The study of the structure of body parts and their relationships to one another is called:
A. Physiology
B. Anatomy
C. Pathology
D. Histology
Answer: B
Rationale: Anatomy is the scientific discipline that investigates the structure of the body.
Physiology examines function, pathology studies disease processes, and histology focuses
on tissues at the microscopic level. Anatomy provides the structural framework upon
which physiological understanding is built.
2. The maintenance of a relatively stable internal environment despite continuous external
changes is termed:
,A. Metabolism
B. Homeostasis
C. Anabolism
D. Catabolism
Answer: B
Rationale: Homeostasis refers to the dynamic state of equilibrium within the body's
internal environment. Metabolism encompasses all chemical reactions (anabolism builds
molecules, catabolism breaks them down). The body employs numerous regulatory
mechanisms to maintain homeostatic conditions necessary for survival.
3. Which anatomical plane divides the body into anterior and posterior portions?
A. Sagittal plane
B. Frontal (coronal) plane
C. Transverse plane
D. Midsagittal plane
Answer: B
Rationale: The frontal plane, also called the coronal plane, divides the body into front
(anterior) and back (posterior) sections. The sagittal plane divides into left and right
portions, the transverse plane divides into superior and inferior portions, and the
midsagittal plane divides into equal left and right halves.
4. The transverse plane divides the body into:
A. Left and right portions
B. Anterior and posterior portions
C. Superior and inferior portions
D. Medial and lateral portions
Answer: C
Rationale: The transverse (horizontal) plane runs parallel to the ground, creating superior
(upper) and inferior (lower) body divisions. This plane is also referred to as the cross-
sectional plane and is essential for imaging techniques like CT scans.
5. Which term describes a position closer to the midline of the body?
,A. Lateral
B. Distal
C. Medial
D. Proximal
Answer: C
Rationale: Medial indicates a structure positioned nearer to the body's midline. Lateral
refers to structures farther from the midline. Proximal and distal describe relative positions
along limbs, with proximal being closer to the point of attachment and distal being farther
away.
6. The abdominopelvic region located in the center just below the sternum is called the:
A. Hypogastric region
B. Epigastric region
C. Umbilical region
D. Lumbar region
Answer: B
Rationale: The epigastric region is positioned superior to the umbilical region and directly
beneath the sternum. The hypogastric region lies inferior to the umbilical region, the
umbilical region is centered around the navel, and the lumbar regions are lateral to the
umbilical region.
7. Which cavity is located superior to the diaphragm?
A. Abdominopelvic cavity
B. Thoracic cavity
C. Pelvic cavity
D. Spinal cavity
Answer: B
Rationale: The thoracic cavity lies above the diaphragm and contains the heart, lungs,
esophagus, trachea, and major blood vessels. The abdominopelvic cavity lies below the
diaphragm. The pelvic cavity is the inferior portion of the abdominopelvic cavity, and the
spinal cavity houses the spinal cord.
8. The serous membrane that surrounds the lungs is called the:
, A. Pericardium
B. Peritoneum
C. Pleura
D. Meninges
Answer: C
Rationale: The pleura is the serous membrane enveloping each lung and lining the thoracic
cavity. The pericardium surrounds the heart, the peritoneum lines the abdominopelvic
cavity, and the meninges cover the brain and spinal cord. Serous membranes reduce
friction between moving organs.
9. Which directional term means "toward the head" or "above"?
A. Inferior
B. Caudal
C. Superior
D. Ventral
Answer: C
Rationale: Superior (cranial) indicates a position above or toward the head. Inferior
(caudal) indicates below or toward the feet. Ventral (anterior) refers to the front, and dorsal
(posterior) refers to the back.
10. The study of tissues is specifically called:
A. Cytology
B. Histology
C. Embryology
D. Pathophysiology
Answer: B
Rationale: Histology is the microscopic study of tissues and their cellular organization.
Cytology focuses on individual cells, embryology studies development before birth, and
pathophysiology examines functional changes associated with disease.
11. Which level of structural organization is composed of two or more tissue types working
together for a common function?
