Q1 Question 1 of 75
During a cadaver lab, a student is asked to identify the directional term that describes the wrist
relative to the elbow. The instructor emphasizes that precise anatomical terminology is critical
for clear communication among healthcare professionals. The student recalls that the wrist is
farther from the trunk than the elbow along the upper limb.
A. Distal
B. Proximal
C. Lateral
D. Superficial
Correct Answer: A
Rationale:
The term distal describes a structure farther from the point of attachment or origin, and the wrist is farther
from the shoulder than the elbow. Proximal would describe a structure closer to the point of attachment,
which is the opposite of the correct relationship.
Q2 Question 2 of 75
A surgeon is planning an incision that will separate the body into anterior and posterior
portions. She explains to the surgical team that selecting the correct body plane is essential for
accessing the target organs without damaging adjacent structures. The plane she requires
divides the body into front and back sections.
A. Sagittal plane
B. Frontal plane
C. Transverse plane
D. Oblique plane
Correct Answer: B
Rationale:
The frontal (coronal) plane divides the body into anterior and posterior portions. The sagittal plane divides
the body into left and right portions, while the transverse plane divides it into superior and inferior portions,
neither of which matches the surgeon's requirement.

, Q3 Question 3 of 75
In an anatomy lecture, the professor describes the thoracic cavity and its subdivisions.
Students must understand which serous membrane directly covers the surface of the lungs to
correctly interpret clinical imaging reports. The membrane in direct contact with the lung tissue
itself is identified.
A. Parietal pleura
B. Visceral pericardium
C. Visceral pleura
D. Parietal pericardium
Correct Answer: C
Rationale:
The visceral pleura is the serous membrane that directly covers the lung surface, while the parietal pleura
lines the thoracic wall. The pericardium surrounds the heart, not the lungs, making those choices incorrect
for this scenario.
Q4 Question 4 of 75
A researcher studying homeostatic mechanisms observes that when blood glucose rises after
a meal, the pancreas releases insulin to lower glucose levels. This regulation exemplifies a
fundamental principle of physiology that maintains stable internal conditions. The specific
mechanism described is best characterized as which type of feedback.
A. Positive feedback
B. Feed-forward control
C. Neutral feedback
D. Negative feedback
Correct Answer: D
Rationale:
Negative feedback works to reverse a change and return the body to a set point, as insulin reduces
elevated blood glucose. Positive feedback amplifies a change rather than reversing it, and feed-forward
control anticipates changes before they occur, neither of which describes this insulin-mediated response.

, Q5 Question 5 of 75
A chemistry instructor demonstrates that carbon has six protons and typically six neutrons in
its nucleus. Students learn that the number of protons determines an element's identity and
that isotopes of an element differ in their neutron count. An atom of carbon-14 differs from
carbon-12 by having additional neutrons, which changes its mass number.
A. Two more neutrons than carbon-12
B. Two more protons than carbon-12
C. Two fewer electrons than carbon-12
D. Two more electrons than carbon-12
Correct Answer: A
Rationale:
Carbon-14 has 8 neutrons while carbon-12 has 6 neutrons, a difference of 2 neutrons, which defines the
different mass numbers. The number of protons (atomic number) remains the same at 6 for all carbon
isotopes, and electron count does not define isotope differences.
Q6 Question 6 of 75
A biochemist explains that sodium chloride dissolves in water because the sodium and
chloride ions are attracted to the polar water molecules. This interaction involves the transfer of
electrons from sodium to chlorine during bond formation. The type of bond that holds NaCl
together in its solid form is identified.
A. Covalent bond
B. Ionic bond
C. Hydrogen bond
D. Van der Waals bond
Correct Answer: B
Rationale:
An ionic bond forms through the complete transfer of electrons from one atom to another, creating
oppositely charged ions that attract each other. Covalent bonds involve electron sharing rather than
transfer, and hydrogen bonds are weak intermolecular attractions, neither of which describes the NaCl
bond.
