1. The term that means “closer to the midline of the body” is:
A) Lateral
B) Medial
C) Proximal
D) Distal
Answer: B – Medial indicates toward the midline; lateral is
away.
Rationale: Anatomical directional terms are essential for
describing locations of body structures. Medial: toward the
midline; lateral: away; proximal: closer to trunk; distal: farther
from trunk.

2. A transverse plane divides the body into:
A) Anterior and posterior portions
B) Superior and inferior portions
C) Left and right portions
D) Frontal and sagittal portions
Answer: B – Transverse (horizontal) plane divides into top
(superior) and bottom (inferior).
Rationale: Coronal (frontal) plane divides anterior/posterior;
sagittal divides left/right; midsagittal divides into equal halves.
3. The term “homeostasis” refers to:
A) A state of dynamic equilibrium within the body
B) The ability to generate heat
C) The breakdown of complex molecules
D) The process of cell division
,Page 3 of 128
Answer: A – Homeostasis is the maintenance of a stable internal
environment despite external changes.
Rationale: Negative feedback loops (e.g., body temperature,
blood glucose) are the primary mechanism. Positive feedback
(e.g., childbirth) amplifies change.
4. The ventral body cavity contains which of the following?
A) Cranial cavity and spinal cavity
B) Thoracic cavity and abdominopelvic cavity
C) Pelvic cavity only
D) Dorsal cavity only
Answer: B – The ventral cavity includes the thoracic and
abdominopelvic cavities.
Rationale: The dorsal cavity contains the cranial and spinal
cavities. The thoracic cavity holds the heart and lungs; the
, Page 4 of 128
abdominopelvic cavity holds digestive, urinary, and reproductive
organs.
5. Which of the following is an example of a negative
feedback mechanism?
A) Blood clotting
B) Uterine contractions during childbirth
C) Regulation of blood glucose by insulin
D) Action potential generation
Answer: C – Insulin lowers elevated blood glucose, restoring
homeostasis.
Rationale: Negative feedback reverses a change; positive
feedback amplifies it (e.g., childbirth, blood clotting).
6. The term “supine” means:
A) Lying face down
