SECTION 1: Introduction to Anatomy & Physiology / Homeostasis (Q1-Q15)
Q1: Which level of structural organization is represented by the heart, an organ
composed of cardiac muscle, connective tissue, and epithelium working together to
pump blood?
A. Organ system [CORRECT]
B. Tissue
C. Cellular
D. Organ
Correct Answer: A
Rationale: The heart is an organ because it consists of multiple tissue types (cardiac
muscle, connective tissue, epithelium) functioning together as a single unit. An organ
system would include the heart plus blood vessels and blood. Tissue and cellular levels
are less complex than an organ.
Q2: A patient presents with tachycardia and elevated blood pressure after a stressful
event. The body responds by slowing the heart rate and lowering blood pressure toward
normal. This represents which type of feedback mechanism?
A. Negative feedback [CORRECT]
B. Positive feedback
C. Neural integration
D. Homeostatic failure
Correct Answer: A
Rationale: Negative feedback reverses a change to restore homeostasis; here the
response counteracts the initial elevation in heart rate and blood pressure. Positive
feedback amplifies changes rather than reversing them. Neural integration and
homeostatic failure do not describe this restorative mechanism.
Q3: The anatomical term "distal" refers to a structure that is:
A. Farther from the point of attachment or origin [CORRECT]
B. Closer to the midline of the body
,C. Closer to the point of attachment or origin
D. Toward the front of the body
Correct Answer: A
Rationale: Distal means farther from the trunk or point of attachment, while proximal
means closer. Medial refers to closer to the midline, and anterior refers to toward the
front of the body.
Q4: The plane that divides the body into superior and inferior portions is the:
A. Transverse plane [CORRECT]
B. Sagittal plane
C. Frontal (coronal) plane
D. Midsagittal plane
Correct Answer: A
Rationale: The transverse (horizontal) plane creates superior and inferior divisions. The
sagittal plane divides left from right, the frontal plane divides anterior from posterior,
and the midsagittal is a specific sagittal cut through the midline.
Q5: Which body cavity contains the brain and is protected by the cranium?
A. Cranial cavity [CORRECT]
B. Vertebral cavity
C. Thoracic cavity
D. Abdominopelvic cavity
Correct Answer: A
Rationale: The cranial cavity houses the brain within the skull. The vertebral cavity
contains the spinal cord, the thoracic cavity contains the heart and lungs, and the
abdominopelvic cavity contains digestive and urinary organs.
Q6: A laboratory technician is examining tissue samples and needs to identify which
plane produces equal right and left halves. This is achieved by which section?
A. Midsagittal section [CORRECT]
B. Parasagittal section
C. Frontal section
D. Oblique section
Correct Answer: A
,Rationale: A midsagittal section passes through the midline, creating mirror-image right
and left halves. A parasagittal section is off-center, a frontal section divides anterior
from posterior, and an oblique section is at an angle.
Q7: Homeostasis is best defined as:
A. The maintenance of relatively stable internal conditions despite external changes
[CORRECT]
B. The elimination of all metabolic waste products
C. The constant increase in body temperature during exercise
D. The equilibrium between acid and base concentrations only
Correct Answer: A
Rationale: Homeostasis refers to dynamic equilibrium of the internal environment. It
involves regulation of multiple variables, not just waste elimination, temperature
increase, or pH balance alone.
Q8: In anatomical position, the palms are facing:
A. Anteriorly (forward) [CORRECT]
B. Posteriorly (backward)
C. Medially (toward the midline)
D. Inferiorly (downward)
Correct Answer: A
Rationale: Standard anatomical position requires the body erect, feet together, palms
facing anteriorly. This universal reference prevents confusion when describing body
structures.
Q9: The dorsal body cavity is subdivided into which two cavities?
A. Cranial and vertebral [CORRECT]
B. Thoracic and abdominopelvic
C. Pleural and pericardial
D. Pelvic and abdominal
Correct Answer: A
Rationale: The dorsal cavity contains the cranial cavity (brain) and vertebral cavity
(spinal cord). The thoracic and abdominopelvic cavities are part of the ventral body
cavity.
, Q10: A patient has a superficial wound on the skin of the anterior forearm. Which term
best describes the wound's location relative to the bone?
A. Superficial (external) [CORRECT]
B. Deep (internal)
C. Proximal
D. Distal
Correct Answer: A
Rationale: Superficial means near the surface; the skin is superficial to the underlying
bone. Deep would mean farther from the surface, while proximal and distal describe
relative distance from the trunk.
Q11: Which feedback mechanism is responsible for blood clotting, where platelet
activation triggers more platelet activation until a clot forms?
A. Positive feedback [CORRECT]
B. Negative feedback
C. Neutral feedback
D. Adaptive feedback
Correct Answer: A
Rationale: Blood clotting is a classic positive feedback loop because the output
amplifies the original stimulus. Negative feedback would counteract the stimulus rather
than amplifying it.
Q12: The serous membrane lining the thoracic cavity and covering the lungs is called
the:
A. Pleura [CORRECT]
B. Peritoneum
C. Pericardium
D. Meninges
Correct Answer: A
Rationale: The pleura is the serous membrane of the thoracic cavity and lungs. The
peritoneum lines the abdominopelvic cavity, the pericardium covers the heart, and the
meninges surround the brain and spinal cord.
Q13: Which of the following is NOT a necessary life function required for survival?
A. Growth (increase in size) [CORRECT]
B. Maintaining boundaries
