19) briefly describe the difference between tonic and phasic receptors, and illustrate this
difference by sketching graphs showing any type of stimulus (as a rectangular wave),
the receptor potentials generated by each type of receptor, and the resulting action

numbers on your axes; rather you are to demonstrate you understand the relative
differences in the responses.
