Chapter 1: An Introduction to the Human Body
1. A researcher is studying the transition of unspecialized mesenchymal cells into
osteoblasts (bone-forming cells). This process of functional specialization is known as:
A. Growth
B. Reproduction
C. Differentiation
D. Anabolism
Answer>>C
Explanation: Differentiation is the process by which unspecialized cells (like stem cells)
become specialized in structure and function. Growth refers to an increase in size/number,
while anabolism is the "building up" phase of metabolism.
2. A patient presents with a sharp pain in the chest that worsens with deep breathing. A
physician suspects pleurisy. Which of the following best describes the
structural-functional relationship involved in this condition?
A. Increased production of serous fluid reduces friction
B. Inflammation of the serous membranes leads to increased friction between layers
C. The diaphragm has herniated into the mediastinum
D. The parietal pericardium is rubbing against the visceral pleura
Answer>>B
Explanation: Serous membranes produce fluid to allow organs to slide without friction. In
pleurisy, the pleural membranes are inflamed and rough, leading to painful friction during
lung expansion (ventilation).
3. A 19-year-old athlete collapses during a marathon in high humidity. Her core
temperature is 104°F (40°C). Her body’s failure to maintain a stable internal temperature
despite environmental changes represents a failure of:
A. Catabolism
B. Differentiation
, 4
C. Homeostasis
D. The appendicular system
Answer>>C
Explanation: Homeostasis is the state of steady internal conditions maintained by living
things. When environmental heat exceeds the body's ability to dissipate it
(thermoregulation), homeostasis fails, leading to heatstroke.
4. During childbirth, the stretching of the cervix triggers the release of oxytocin, which
causes stronger uterine contractions, further stretching the cervix. This cycle continues
until delivery. This is a classic example of:
A. Negative feedback
B. A paradoxical reflex
C. Positive feedback
D. Homeostatic equilibrium
Answer>>C
Explanation: Positive feedback intensifies a change in the body’s physiological condition
rather than reversing it. A definitive endpoint (the birth of the baby) is required to break
the loop.
5. In a clinical imaging report, a radiologist describes a "transverse section of the thorax at
the level of the T4 vertebra." In which orientation was the body sliced?
A. Into right and left halves
B. Into anterior and posterior halves
C. Into superior and inferior portions
D. Diagonally at a 45-degree angle
Answer>>C
Explanation: A transverse (horizontal) plane divides the body or organ into upper
(superior) and lower (inferior) portions.
6. A patient suffers a laceration to the "carpal" region. Where should the nurse apply the
bandage?
