WebMost of your synapses are chemical synapses, meaning that information is carried by chemical messengers from one neuron to the next. In the article on synapses, we discussed how synaptic transmission works. Here, we’ll focus on neurotransmitters, the chemical messengers released from neurons at synapses so that they can “talk” to neighboring cells.

WebSep 4, 2024 · Figure 11.4. 4 shows the change in potential of the axon membrane during an action potential. The nerve goes through a brief refractory period before racing resting potential. During the refractory period, another action potential cannot be generated. In myelinated neurons, ion flows occur only at the nodes of Ranvier. WebThe transmission of a nerve impulse or action potential from one neuron to another neuron or non-neuron cell, across the synapse, is called synaptic transmission. The process of synaptic transmission can be easily understood after studying the structure and the type of synapses involved.
