Section 1: General Anatomy & Organization (Questions 1–10)
1. Which of the following is the correct order of structural organization from
simplest to most complex?
• A) Tissue → Cell → Organ → Organ System → Organism
• B) Cell → Tissue → Organ → Organ System → Organism
• C) Organ → Tissue → Cell → Organ System → Organism
• D) Cell → Organ → Tissue → Organ System → Organism
Rationale: The hierarchy starts with cells (smallest living unit), then tissues
(groups of similar cells), then organs (multiple tissues), then organ systems, then
the organism.
2. Which body plane divides the body into equal left and right halves?
• A) Coronal plane
• B) Mid-sagittal plane
• C) Transverse plane
• D) Frontal plane
Rationale: The mid-sagittal (median) plane divides the body into equal left and
right halves. Coronal/frontal divides anterior/posterior; transverse divides
superior/inferior.
3. The dorsal body cavity contains which of the following?
, • A) Brain and spinal cord
• B) Heart and lungs
• C) Stomach and liver
• D) Kidneys and bladder
Rationale: The dorsal cavity includes the cranial cavity (brain) and vertebral canal
(spinal cord). Thoracic and abdominopelvic cavities are ventral.
4. Which term describes a position closer to the point of attachment of a limb?
• A) Distal
• B) Proximal
• C) Lateral
• D) Superficial
Rationale: Proximal = nearer to trunk/attachment; distal = farther away.
5. Which feedback mechanism is most commonly used to maintain
homeostasis?
• A) Positive feedback
• B) Negative feedback
• C) Feed-forward control
• D) Homeostatic imbalance
Rationale: Negative feedback reverses a change (e.g., body temperature, blood
glucose). Positive feedback amplifies change (e.g., childbirth).
6. The abdominopelvic region located in the upper right, beneath the ribs, is
the:
• A) Epigastric region
• B) Right hypochondriac region
• C) Right lumbar region
• D) Right iliac region
, Rationale: The hypochondriac regions are the upper lateral quadrants, right side
contains liver and gallbladder.
7. Which of the following is an example of a positive feedback loop?
• A) Regulation of blood pressure
• B) Control of blood glucose by insulin
• C) Release of oxytocin during childbirth
• D) Temperature regulation by sweating
Rationale: Oxytocin causes stronger uterine contractions, which stimulate more
oxytocin release – a positive feedback loop.
8. The serous membrane lining the thoracic cavity and covering the lungs is
the:
• A) Peritoneum
• B) Pericardium
• C) Pleura
• D) Mesentery
Rationale: Pleura surrounds lungs; pericardium surrounds heart; peritoneum
surrounds abdominal organs.
9. Which directional term means "toward the back"?
• A) Dorsal
• B) Ventral
• C) Superior
• D) Medial
Rationale: Dorsal = back; ventral = belly/front.
10. The study of the function of body structures is called:
• A) Anatomy
• B) Physiology
• C) Histology
