When a postsynaptic neuron is excited, the action potential generally first erupts in the axon hillock mainly due toDuring a reflex activity, after the stimulus stops, the motor nerve fiber can still generate action potentials. Physiology describes this phenomenon using which of the following concepts?The main mechanism for the generation of a fast excitatory postsynaptic potential (fast EPSP) isIn the central nervous system, which type of glial cell forms myelin sheaths?Which of the following changes can directly reduce the release of neurotransmitters at the synaptic terminal due to an action potential?
