How the axon fires
NettetAt the peak action potential, K + channels open and K + begins to leave the cell. At the same time, Na + channels close. The membrane becomes hyperpolarized as K + ions continue to leave the cell. The hyperpolarized membrane is in … NettetAn axon plays a most critical role by conducting the signal to the target cell via synapses. The conduction of the message can be continuous or saltatory. A neuron terminates on one of the three target cells like muscle, gland and another neuron, which causes muscles to contract, glands to secrete and neuron to transmit the action potential.
