WebAxon terminals (also called synaptic boutons, terminal boutons, or end-feet) are distal terminations of the telodendria (branches) of an axon.An axon, also called a nerve fiber, is a long, slender projection of a nerve cell, or neuron, that conducts electrical impulses called action potentials away from the neuron's cell body, or soma, in order to transmit those … WebSize. Action potentials travel down neuronal axons in an ion cascade. Positive ions (mostly sodium ions) flow into the cell body, which triggers transmembrane channels at the start of the axon to open and to let in more positive ions. These new positive ions trigger the channels next to them, which let in even more positive ions. crestwood platinum 50 piece setWebDec 5, 2024 · Signal transmission at synapse is a chemical process.
