How the axon fires
NettetGoing down the length of the axon, the action potential is propagated because more voltage-gated Na + channels are opened as the depolarization spreads. This spreading occurs because Na + enters through the channel … Nettet2. apr. 2024 · Basic Physiology of a Neuron and How it Fires Describe the basic physiology of a neuron. Detail the manner by which neurons fire action potentials and how neurons communicate with one another across synapses. Outline the process of how an action petential occurs and hoe it propagates down an axon.
