Web15 de abr. de 2024 · The neurotransmitters transmit the nerve impulse to the post synaptic fibre, by diffusing across the synaptic cleft and binding to receptor molecules on the post synaptic membrane. This results in a series of reactions that open "channel shaped" protein molecules. Electrically charged ions then flow through the channels in or out of the neurons. Web26 de mar. de 2016 · Neurons don't touch. The signal must traverse the synapse to continue on its path through the nervous system. Electrical conduction carries an impulse across synapses in the brain, but in other parts of the body, impulses are carried across synapses as the following chemical changes occur: Calcium gates open. WebNeurotransmitters are how we communicate between one cell and the next. Synapses between neurons are either excitatory or inhibitory – and that all comes down to the neurotransmitter released. Excitatory neurotransmitters cause the signal to propagate - more action potentials are triggered. Inhibitory signals work to cancel the signal. howells on gilligans island
