,Multiple Choice Questions (25)
1. Which of the following best defines physiology?
a) The study of the structure of organisms
b) The study of the chemical processes in living organisms
c) The study of the functional processes of living organisms
d) The study of evolutionary relationships among species
Answer: c) The study of the functional processes of living organisms
Explanation: Physiology focuses on how organisms function, including molecular,
cellular, and systemic processes. Structure is anatomy; chemical processes is
biochemistry.
2. Homeostasis refers to:
a) Maintaining a constant internal environment despite external changes
b) Changing internal conditions to match the external environment
c) The process of evolution over time
d) The breakdown of nutrients for energy
Answer: a) Maintaining a constant internal environment despite external changes
Explanation: Homeostasis is the maintenance of relatively stable internal conditions
(e.g., temperature, pH, ion balance) through regulatory mechanisms.
3. Which type of feedback mechanism amplifies a physiological change?
a) Negative feedback
b) Positive feedback
, c) Feedforward regulation
d) Homeostatic inhibition
Answer: b) Positive feedback
Explanation: Positive feedback amplifies a response (e.g., oxytocin during childbirth),
while negative feedback reverses a change to maintain stability.
4. Negative feedback loops typically involve:
a) A stimulus that increases the original response
b) A sensor, integrator, and effector that reverse the stimulus
c) No control center
d) Only hormonal signals
Answer: b) A sensor, integrator, and effector that reverse the stimulus
Explanation: Negative feedback systems detect a deviation from set point (sensor),
compare to set point (integrator/control center), and activate effectors to oppose the
change.
5. Which example best illustrates negative feedback?
a) Blood clotting cascade
b) Uterine contractions during labor
c) Regulation of blood glucose by insulin
d) Action potential generation in neurons
Answer: c) Regulation of blood glucose by insulin
Explanation: High blood glucose triggers insulin release, which lowers glucose levels
back to set point, reversing the initial change. The others are positive feedback.
