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 neurotransmitters can now “swim” (diffuse) through the synaptic cleft, until they reach the postsynaptic neuron. The membrane of the postsynaptic neuron contains a few channels (receptors) that control how a neurotransmitter can be translated into an electrical signal. WebSynaptic transmission is the key process in the integrative action of the nervous system. Synaptic transmission is the process at synapses by which a chemical signal (a transmitter) is released from one neuron and diffuses to other neurons or target cells where it generates a signal which excites, inhibits or modulates cellular activity.

Web5 Steps to Chemical Synaptic Transmission In a gist: The electrical signal cannot “jump” over that gap. Instead, at the point of synaptic junction between two neurons, the presynaptic neuron (at the presynaptic terminal) “translates” the electrical signal into a chemical message (the neurotransmitter) – Step 1 & 2.
