Webchemical transmission of nerve impulse In neurotransmitter: Neurotransmitter signaling …by a gap called the synaptic cleft. The synaptic cleft, presynaptic terminal, and receiving dendrite of the next cell together form a junction known as the synapse. Read More In nervous system: Axon WebMost synapses are chemical; these synapses communicate using chemical messengers. Other synapses are electrical; in these synapses, ions flow directly between cells. At a chemical synapse, an action potential triggers the presynaptic neuron to release … This is the post-synaptic neuron. And the space between the two neurons, … Neurons (or nerve cells) are specialized cells that transmit and receive electrical …
WebJun 8, 2024 · Neurotransmission at a chemical synapse begins with the arrival of an action potential at the presynaptic axon terminal. When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated Na + channels. Na + ions enter the cell, further depolarizing the presynaptic membrane.
