This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Nervous System, Subject name: Physiology
True about generator potential: 
Select and explain. 
A. Graded, B. Follows all or none law, C. Propagated, D. Does not show summation
A: Graded
Answer: A: Graded 
Explanation: Generator potentialare graded potentials whose magnitude is propotional to ghe intensity of the stimulus . Graded potentials have different names depending on which type of stimulus causes them and where they occur. For eg, when a graded potential occurs in the dendrites or cell body of a neuron in response to a neurotransmitter, it is called a postsynaptic potential. On the other hand, the graded potentials that occur in sensory receptors are termed receptor or generator potentials. Other examples: end-plate potentials, pacemaker potentials, and slow wave potentials. PROPEIES OF GRADED POTENTIAL
