Section 1: Introduction to the Human Body and Homeostasis
1. Which branch of science is primarily concerned with the study of the structure
of the body and the relationships between its parts?
A) Physiology
B) Histology
C) Anatomy
D) Pathology
Rationale: Anatomy is defined as the study of the structure of the body and the
relationships among its parts, whereas physiology studies function.
2. Which of the following sequences correctly represents the levels of structural
organization from the simplest to the most complex?
A) Cell, tissue, organ, molecule, organism
B) Molecule, cell, tissue, organ, system, organism
C) Organ, tissue, cell, molecule, organism
D) Tissue, cell, organ, system, organism
Rationale: The correct hierarchy is chemical (molecule), cellular, tissue, organ,
organ system, and organism.
3. A patient is lying face down on the examination table, which means the patient
is in which of the following anatomical positions?
1|Page
,Page 2 of 63
A) Supine
B) Prone
C) Trendelenburg
D) Fowler's
Rationale: The prone position describes a person lying face down, whereas supine
describes lying face up.
4. Which anatomical plane divides the body into equal right and left halves?
A) Transverse plane
B) Frontal (coronal) plane
C) Midsagittal (median) plane
D) Oblique plane
Rationale: The midsagittal or median plane divides the body into equal right and
left halves.
5. The term "distal" means that a body part is situated in which direction relative
to another structure?
A) Closer to the midline
B) Closer to the point of attachment
C) Farther from the point of attachment to the body
D) Toward the head
Rationale: Distal means farther from the origin or point of attachment, whereas
proximal means closer.
6. Which body cavity is located superior to the diaphragm and contains the heart
and lungs?
A) Abdominopelvic cavity
B) Dorsal cavity
C) Thoracic cavity
D) Pelvic cavity
Rationale: The thoracic cavity is superior to the diaphragm and houses the heart,
lungs, and mediastinal structures.
7. Homeostasis is best defined as the body's ability to maintain what type of
internal environment despite external changes?
2|Page
,Page 3 of 63
A) A constantly changing and variable state
B) A relatively stable and balanced internal environment
C) An environment that is entirely independent of nervous control
D) A state of complete anatomical stillness
Rationale: Homeostasis refers to the maintenance of a relatively stable internal
environment around a set point.
8. Which feedback mechanism is illustrated when a rise in blood glucose
stimulates insulin release, which then lowers blood glucose back to normal?
A) Positive feedback
B) Negative feedback
C) Feed-forward control
D) Amplifying feedback
Rationale: Negative feedback reverses the initial change; insulin lowers glucose,
restoring homeostasis.
9. Which of the following is an example of a positive feedback loop in the human
body?
A) Regulation of body temperature
B) Regulation of blood pressure
C) Uterine contractions during childbirth
D) Regulation of blood glucose by insulin
Rationale: Positive feedback amplifies a change; uterine contractions intensify
until delivery, which is a classic example.
10. The umbilicus is located in which abdominopelvic region?
A) Right iliac region
B) Umbilical region
C) Hypogastric region
D) Left lumbar region
Rationale: The umbilical region is the central region of the abdomen containing
the umbilicus (navel).
11. Which directional term correctly describes the relationship of the head to the
chest?
3|Page
, Page 4 of 63
A) The head is inferior to the chest
B) The head is superior to the chest
C) The head is distal to the chest
D) The head is posterior to the chest
Rationale: Superior (cranial) means toward the head, so the head is superior to
the chest.
12. A surgeon makes an incision that divides the body into anterior and posterior
sections. Which plane was used?
A) Sagittal plane
B) Transverse plane
C) Frontal (coronal) plane
D) Midsagittal plane
Rationale: The frontal or coronal plane divides the body into anterior (front) and
posterior (back) portions.
13. Which of the following best describes the role of a receptor in a homeostatic
control mechanism?
A) It carries out the response to restore balance
B) It detects changes in the internal or external environment
C) It integrates information and determines the set point
D) It permanently alters the genetic code of the cell
Rationale: Receptors monitor stimuli and send input to the control center for
integration.
14. The mediastinum is located within which larger body cavity?
A) Abdominal cavity
B) Pelvic cavity
C) Thoracic cavity
D) Cranial cavity
Rationale: The mediastinum is the central compartment of the thoracic cavity,
containing the heart and great vessels.
15. Which of the following statements most accurately distinguishes physiology
from anatomy?
