Study with Quizlet and memorize flashcards containing terms like Can be depolarizing or hyperpolarizing depending on stimulus or - Amplitude is proportional to the strength of.

On the other hand action potentials occur when graded potentials reach the axon hillock at a certain level of. What are the two types of graded potentials. 519 130129130130 Action Potentials are a result of Graded Potentials.

Graded potentials occur when neurotransmitter is released into the synaptic cleft via exocytosis. Graded potential amplitude decreases away from point of channel opening. Initiated by environmental stimulus receptor by NT synapse or spontaneously.

Action potential propagation to neighboring membrane regions is. Graded potentials dissipate with distance from stimulus. Graded potentials travel by passive spread electrotonic spread to neighboring membrane regions.
