Section 1: Anatomical Terminology & Body Organization (15
Questions)
Q1: Which directional term describes a position closer to the midline of the body?
● A) Lateral
● B) Proximal
● C) Medial
● D) Distal
🧠 ANSWER ✔✔ C) Medial [CORRECT]
Rationale: Medial refers to structures closer to the midline (median plane), while lateral
refers to structures farther from the midline. This is fundamental for describing anatomical
relationships in clinical documentation and physical assessment. Proximal/distal describe
positions relative to the trunk or point of attachment.
Q2: The plane that divides the body into equal left and right halves is called:
● A) Frontal plane
● B) Midsagittal plane
● C) Transverse plane
● D) Coronal plane
🧠 ANSWER ✔✔ B) Midsagittal plane [CORRECT]
Rationale: The midsagittal (median) plane passes through the midline, creating equal left and
right portions. The sagittal plane is parallel but doesn't necessarily create equal halves.
Frontal/coronal planes divide anterior from posterior; transverse planes divide superior from
inferior.
,Q3: Which body cavity contains the brain?
● A) Vertebral cavity
● B) Thoracic cavity
● C) Cranial cavity
● D) Abdominal cavity
🧠 ANSWER ✔✔ C) Cranial cavity [CORRECT]
Rationale: The cranial cavity within the skull houses and protects the brain. The vertebral
cavity contains the spinal cord. The dorsal body cavity consists of both cranial and vertebral
cavities. Thoracic and abdominal cavities are part of the ventral cavity.
Q4: The membrane that lines the abdominal cavity wall is called:
● A) Visceral peritoneum
● B) Parietal peritoneum
● C) Visceral pleura
● D) Parietal pleura
🧠 ANSWER ✔✔ B) Parietal peritoneum [CORRECT]
Rationale: The parietal peritoneum lines the abdominal cavity walls, while the visceral
peritoneum covers abdominal organs. "Parietal" always refers to cavity walls; "visceral" refers
to organs. Pleural membranes surround the lungs, not abdominal structures.
Q5: What type of feedback mechanism amplifies a change from the normal state?
● A) Negative feedback
● B) Positive feedback
● C) Homeostatic feedback
● D) Neutral feedback
🧠 ANSWER ✔✔ B) Positive feedback [CORRECT]
Rationale: Positive feedback amplifies or reinforces changes, moving the system away from
homeostasis temporarily. Examples include blood clotting and childbirth (oxytocin release).
Negative feedback, the most common homeostatic mechanism, opposes changes to
maintain stability (e.g., temperature regulation, blood glucose control).
Q6: A nurse is documenting a wound location. Which term indicates the wound is on the palm
side of the hand?
, ● A) Dorsal
● B) Plantar
● C) Palmar
● D) Posterior
🧠 ANSWER ✔✔ C) Palmar [CORRECT]
Rationale: Palmar refers to the anterior (palm) surface of the hand; dorsal refers to the
posterior (back) surface. Plantar refers to the sole of the foot. Using precise anatomical
terminology prevents documentation errors that could affect patient care continuity.
Q7: Which abdominopelvic region is located immediately superior to the hypogastric (pubic)
region?
● A) Right iliac region
● B) Umbilical region
● C) Epigastric region
● D) Left lumbar region
🧠 ANSWER ✔✔ B) Umbilical region [CORRECT]
Rationale: The nine abdominopelvic regions are arranged in three rows: epigastric (superior),
umbilical (middle), and hypogastric (inferior), flanked by right/left hypochondriac, lumbar, and
iliac regions. The umbilical region is directly superior to the hypogastric region.
Q8: In anatomical position, the palms face:
● A) Posteriorly
● B) Medially
● C) Anteriorly
● D) Laterally
🧠 ANSWER ✔✔ C) Anteriorly [CORRECT]
Rationale: Standard anatomical position requires the body erect, feet together, arms at sides
with palms facing anteriorly (forward). This universal reference position ensures consistent
anatomical descriptions regardless of the body's actual orientation.
Q9: Which body cavity is divided into pleural, pericardial, and mediastinal portions?
● A) Abdominopelvic cavity
● B) Thoracic cavity
● C) Cranial cavity
, ● D) Spinal cavity
🧠 ANSWER ✔✔ B) Thoracic cavity [CORRECT]
Rationale: The thoracic cavity contains the pleural cavities (lungs), pericardial cavity (heart),
and mediastinum (central compartment containing heart, trachea, esophagus, thymus).
Understanding these subdivisions is essential for interpreting chest imaging and surgical
approaches.
Q10: The term "proximal" in anatomy refers to:
● A) Closer to the midline
● B) Closer to the point of attachment or trunk
● C) Away from the surface
● D) Closer to the surface
🧠 ANSWER ✔✔ B) Closer to the point of attachment or trunk [CORRECT]
Rationale: Proximal describes a position nearer to the trunk or point of origin; distal
describes a position farther from the trunk. In nursing assessment, proximal/distal are used
to describe vascular access sites, injuries, and neurological assessments of extremities.
Q11: A patient has a rash on the anterior surface of the knee. Which term describes this
location?
● A) Popliteal
● B) Patellar
● C) Plantar
● D) Calcaneal
🧠 ANSWER ✔✔ B) Patellar [CORRECT]
Rationale: The patellar region refers to the anterior knee (kneecap area). Popliteal refers to
the posterior knee. Plantar is the sole of the foot; calcaneal is the heel. Using specific
regional terms ensures precise communication among healthcare providers.
Q12: Which serous membrane covers the lungs?
● A) Parietal pleura
● B) Visceral pleura
● C) Parietal pericardium
● D) Visceral peritoneum
