Question 1
The femur is ______ to the skin of the thigh.
A) Medial
B) Anterior
C) Posterior
D) Deep
Correct Answer: D) Deep
Explanation: The femur is located deep within the thigh, beneath the
skin and muscle layers. "Deep" means farther from the body
surface. The femur is not medial, anterior, or posterior to the skin—
it is simply deep to it.
Question 2
The liver is found in which body cavities?
,A) Ventral cavity, thoracic cavity, pericardial cavity
B) Ventral cavity, abdominopelvic cavity, abdominal cavity, peritoneal
cavity
C) Dorsal cavity, abdominal cavity, pelvic cavity
D) Ventral cavity, abdominopelvic cavity, pelvic cavity
Correct Answer: B) Ventral cavity, abdominopelvic cavity, abdominal
cavity, peritoneal cavity
Explanation: The liver is located in the ventral cavity, specifically
within the abdominopelvic cavity. More precisely, it sits in the
abdominal cavity and is surrounded by the peritoneal cavity. The
liver is NOT in the thoracic, pericardial, dorsal, cranial, or pelvic
cavities.
Question 3
The parietal pleura directly covers the surface of the lungs.
A) True
B) False
Correct Answer: B) False
Explanation: The visceral pleura directly covers the surface of the
lungs, not the parietal pleura. The parietal pleura lines the thoracic
cavity wall. Remember: "visceral" covers the organ itself; "parietal"
lines the cavity wall.
,Question 4
After running a marathon, a patient drinks many liters of water to
overcome dehydration. Soon after, the patient's cells begin to swell, and
symptoms of water intoxication develop. Compared to the cytoplasm,
what was the tonicity of the blood?
A) Isotonic
B) Hypertonic
C) Hypotonic
D) Osmotic
Correct Answer: C) Hypotonic
Explanation: The blood became hypotonic compared to the
cytoplasm. When large volumes of plain water are consumed, the
blood becomes diluted (lower solute concentration). Water moves
from the hypotonic blood into the cells by osmosis, causing them to
swell. If the blood were hypertonic, water would leave cells and they
would shrink.
Question 5
Anatomical position allows for uniformity in naming and identification of
structures.
A) False
B) True
, Correct Answer: B) True
Explanation: Anatomical position is the standard reference position
used in anatomy to ensure consistency when describing body
structures. In this position, the body stands upright, feet flat, arms
at sides, palms facing forward. This standardization allows
healthcare professionals worldwide to communicate clearly.
Question 6
The olecranal region is ______ to the acromial region.
A) Lateral
B) Anterior
C) Distal
D) Superior
Correct Answer: C) Distal
Explanation: The olecranal region refers to the elbow, while the
acromial region refers to the shoulder. Since the elbow is farther
from the trunk than the shoulder, the olecranal region is distal to
the acromial region. "Distal" means farther from the point of origin
or attachment.
Question 7
The pleura covers the heart.
