Section A: Lab 1 – Anatomical Terminology, Body Organization &
Cavities
Q1: A student is standing in the anatomical position on the lab platform. Which of the
following correctly describes this position?
A. Palms facing backward, feet together
B. Body supine with arms crossed over the chest
C. Body erect, feet flat on the floor, arms at the sides, palms facing forward [CORRECT]
D. Body prone with palms facing the thighs
Correct Answer: C
Rationale: The anatomical position is body erect, feet flat, arms at sides with palms
facing forward. Supine (face-up) and prone (face-down) are body positions, not the
anatomical reference position.
Q2: During a lab practical, an instructor makes a cut that divides the body into left and
right portions. What is the name of this plane?
A. Frontal plane
B. Sagittal plane [CORRECT]
C. Transverse plane
D. Oblique plane
Correct Answer: B
Rationale: A sagittal plane divides the body into left and right portions; a frontal plane
divides anterior/posterior, and a transverse plane divides superior/inferior.
Q3: A student is examining a model of the torso. A structure is described as "proximal to
the elbow." Where is this structure located?
A. Closer to the trunk than the elbow [CORRECT]
,B. Farther from the trunk than the elbow
C. Toward the front of the body
D. Below the elbow in position
Correct Answer: A
Rationale: Proximal means closer to the point of attachment/trunk. Distal (B) means
farther from the trunk, anterior refers to front, and inferior refers to below — none of
these match the description.
Q4: An MRI scan shows a tumor located in the cavity surrounded by the ribs and
diaphragm, containing the heart and lungs. Which cavity is described?
A. Abdominopelvic cavity
B. Cranial cavity
C. Dorsal cavity
D. Thoracic cavity [CORRECT]
Correct Answer: D
Rationale: The thoracic cavity is bounded by the thoracic wall and diaphragm and
contains the heart and lungs. The abdominopelvic cavity lies inferior to the diaphragm,
and the dorsal cavity contains the cranial and vertebral cavities.
Q5: While observing a heart model, a student notes that the pericardium reduces friction
as the heart beats. Which membrane type lines this cavity and covers the organ's
surface?
A. Mucous membrane
B. Synovial membrane
C. Serous membrane [CORRECT]
D. Cutaneous membrane
Correct Answer: C
Rationale: Serous membranes (parietal and visceral layers with serous fluid between)
line body cavities and cover organs to reduce friction. Mucous membranes line tracts
open to the exterior, and synovial membranes line joint cavities.
Q6: A physical therapist asks a patient to move a limb away from the midline of the
body. What movement is being performed?
A. Adduction
B. Flexion
C. Abduction [CORRECT]
, D. Extension
Correct Answer: C
Rationale: Abduction moves a limb away from the midline, whereas adduction moves it
toward the midline. Flexion and extension describe changes in joint angle, not
movement relative to the midline.
Q7: A model's patella is described as "anterior to the femur." A student interprets this to
mean the patella is:
A. Behind the femur
B. In front of the femur [CORRECT]
C. Superior to the femur
D. Medial to the femur
Correct Answer: B
Rationale: Anterior means toward the front of the body; therefore the patella (kneecap)
lies in front of the femur. Posterior would mean behind, superior above, and medial
toward the midline.
Q8: During dissection of a cadaver, a student cuts through the umbilical region and
notes organs located in which abdominopelvic quadrant?
A. Right upper quadrant
B. Right lower quadrant
C. Left lower quadrant
D. The umbilical region is a middle region, not a quadrant [CORRECT]
Correct Answer: D
Rationale: Clinicians divide the abdominopelvic cavity into four quadrants (RUQ, LUQ,
RLQ, LLQ), while anatomists use nine regions, including the central umbilical region. The
umbilical region is not a quadrant.
Q9: A spinal needle is inserted into the vertebral canal at L3–L4 to collect cerebrospinal
fluid. Which body cavity is being accessed?
A. Ventral cavity
B. Vertebral (spinal) cavity [CORRECT]
C. Pleural cavity
D. Peritoneal cavity
Correct Answer: B
