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. … Some thought transmission was chemical.
How is information transmitted across a synapse?
Information is passed down the axon of the neuron as an electrical impulse known as action potential. … When the electrical impulse (action potential) reaches these synaptic vesicles, they release their contents of neurotransmitters. Neurotransmitters then carry the signal across the synaptic gap.
How impulses are transmitted across a synapse Igcse?
1) An electrical impulse travels along an axon of the presynaptic neuron. 2) When the impulse reaches the nerve-ending, it releases chemical messengers called neurotransmitters. 3) These chemicals diffuse across the synapse and bind with specific receptor molecules on the membrane of the next neuron.
