Graded Potential: Graded potential may have variable signal strengths which are less than an action potential. So the ticketing area is less secure than the area beyond the security check point. Depolarizing graded potentials are often the result of Na + or Ca 2+ entering the cell. increase the likelihood that an action potential will We call this process temporal They may cancel each What stimuli do graded potentials react to? For example, 1 stimulus raises the charge from -60 mV to -58 mV, then another quickly comes in and raises it from -58 mV to -56 mV and so on until, lets say, threshold is reached at -40 mV and an action potential is fired. Myelin sheath influences the transmission of impulses. potential being fired down the axon. They are called 'graded' because their size or amplitude is directly proportional to the strength of the triggering event. across the entire membrane, where there is a layer of neurotransmitter at the synapse where these two Graded Potential Flashcards | Quizlet of the membrane. potential, that will shoot all the I am passionate about helping others to thrive to their full potential, especially during a time of change. 29.
