WebJan 6, 2024 · At a synapse, one neuron sends a message to a target neuron—another cell. At a chemical synapse, an action potential triggers the presynaptic neuron to release neurotransmitters. These molecules bind to receptors on the postsynaptic cell and make it more or less likely to fire an action potential. How do synapses work BBC Bitesize? WebSynaptic 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.

WebFeb 14, 2024 · A synapse is a combination of the following: Presynaptic endings – which contain the neurotransmitters (chemical messengers). Synaptic clefts – which is the gap between the two neurons. Postsynaptic endings – which contain the sites for receptors (molecules that receive signals for a cell). WebStimulants and depressants affect the synapses between neurones in the nervous system: stimulants cause more neurotransmitter molecules to diffuse across the synapse depressants stop the next neurone sending nerve impulses – they bind to the receptor molecules it needs to respond to the neurotransmitter molecules.
