IVY TECH APHY 101 FINAL EXAM 259 Practice Questions with
Answers & Rationales (2026/2027 Update) pdf
Section 1: Anatomical Terminology & Organization (Questions 1-20)
1. The body's ability to maintain a stable internal environment despite external
changes is called:
A) Metabolism
B) Anabolism
C) Homeostasis
D) Catabolism
Answer: C
Rationale: Homeostasis is the maintenance of a relatively stable internal environment.
Metabolism refers to all chemical reactions in the body. Anabolism is building reactions;
catabolism is breaking down reactions.
2. In the anatomical position, the palms of the hands are facing:
A) Posteriorly
B) Anteriorly (forward)
C) Laterally
D) Medially
,Answer: B
Rationale: In the anatomical position, the body is standing erect, facing forward, with arms
at the sides and palms facing forward. This is the standard reference position for describing
body structures.
3. The directional term "proximal" means:
A) Farther from the point of attachment
B) Closer to the midline
C) Closer to the point of attachment
D) Toward the back
Answer: C
Rationale: Proximal means closer to the point of attachment (e.g., the elbow is proximal to
the wrist). Distal means farther from the point of attachment. Lateral is away from the
midline; medial is toward the midline.
4. The abdominopelvic cavity contains which of the following organs?
A) Heart and lungs
B) Brain and spinal cord
C) Stomach, intestines, and liver
D) Kidneys and bladder
,Answer: C
Rationale: The abdominopelvic cavity contains the stomach, intestines, liver, spleen,
gallbladder, pancreas, kidneys, and reproductive organs. The heart and lungs are in the
thoracic cavity.
5. Which plane divides the body into superior and inferior portions?
A) Sagittal plane
B) Frontal plane
C) Transverse plane
D) Coronal plane
Answer: C
Rationale: The transverse plane (also called horizontal or cross-section) divides the body
into superior (upper) and inferior (lower) portions. The sagittal plane divides into left and
right; the frontal/coronal plane divides into anterior and posterior.
6. The mediastinum is located in which cavity?
A) Abdominopelvic
B) Cranial
C) Thoracic
D) Spinal
, Answer: C
Rationale: The mediastinum is the central region of the thoracic cavity, containing the heart,
trachea, esophagus, and major blood vessels. It is located between the two pleural cavities.
7. Which serous membrane covers the organs within the abdominal cavity?
A) Pleura
B) Pericardium
C) Peritoneum
D) Meninges
Answer: C
Rationale: The peritoneum is the serous membrane lining the abdominal cavity and
covering the abdominal organs. The pleura covers the lungs; the pericardium covers the
heart; the meninges cover the brain and spinal cord.
8. The directional term "ventral" means:
A) Toward the back
B) Toward the belly (front)
C) Toward the head
D) Toward the feet
