Question
Chapter 10, Problem 20RA
Summary Introduction
To review:
Nature of generator potential and its relationship with the stimulus intensity and frequency of action potential.
Introduction:
Generator potentials are generated by sensory receptors due to continuous stimulation of nerve endings. They result in graded increase in membrane potential, which is a function of the nature of the neurons, strength of the stimulus, the periodicity and the nature of the receptors that are responding. Depending upon the need of the body the response could be slow-acting or fast adapting.
