Question 1
pts
What is a reflex?

Describe an autonomic reflex arc and provide an example of this type of arc.
Answer: An autonomic reflex is most often a visceral, internal response that occurs, such as
blood vessel constriction or an increase in heart rate (~1:05).

a) sensory; motor
b) bipolar; multipolar
c) interneuron; sensory
d) motor; sensory


Question 4
4. pts
Describe the basic pathway of a reflex arc.
Answer: Receptor →Sensory neuron → Integration center → Motor neuron → Effector
tissue (~ 2:03).

Question 5
pts
True or False: Since there are no interneurons in the deep tendon reflex arc, the reflex is a slower
reflex.
a) True
b) False

Answer: False; The reflex is more rapid because there are no interneurons (~3:40).
