Updated 2026
1. What is a reflex?
a) A voluntary response that involves higher brain function.
b) An involuntary response that does not involve higher brain function.
c) A conscious decision to move a muscle.
d) A response that always involves multiple interneurons.
Correct Answer: b
2. Which of the following is the best example of an autonomic reflex?
a) Withdrawing your hand from a hot surface.
b) The knee-jerk response.
c) Constriction of blood vessels.
d) Tapping your finger on a table.
Correct Answer: c
3. In a reflex arc, the neuron known as afferent is the ______ neuron, and the
neuron known as efferent is the ______ neuron.
a) motor; sensory
b) bipolar; multipolar
c) interneuron; sensory
d) sensory; motor
Correct Answer: d
, 4. What is the correct order of the basic pathway of a reflex arc?
a) Motor neuron → Integration center → Sensory neuron → Receptor → Effector
tissue
b) Receptor → Sensory neuron → Integration center → Motor neuron → Effector
tissue
c) Effector tissue → Motor neuron → Integration center → Sensory neuron →
Receptor
d) Integration center → Sensory neuron → Receptor → Motor neuron → Effector
tissue
Correct Answer: b
5. The deep tendon reflex is a slower reflex because there are no interneurons in
its arc.
a) True
b) False
Correct Answer: b
6. Why does the deep tendon reflex pathway have two motor pathways?
a) Because one pathway is for conscious control and the other is for unconscious
control.
b) Because muscles work in antagonistic pairs; one muscle needs to contract while
the other relaxes.
c) Because the reflex arc is longer and requires more time to complete.
