Question

When a nerve impulse travels from neuron 1 to neuron 2, neuron 1 is known as the _____. ​gated channel ​presynaptic neuron ​postsynaptic neuron ​dendrite ​synapse?

Answer 1

Answer;

-Presynaptic neuron

Explanation;

-When a nerve impulse travels from neuron 1 to neuron 2, neuron 1 is known as the presynaptic neuron.

-This is a neuron from the axon terminal of which an electrical impulse is transmitted across a synaptic cleft to the cell body or one or more dendrites of a postsynaptic neuron by the release of a chemical neurotransmitter.

- A postsynaptic neuron is a neuron to the cell body or dendrite of which an electrical impulse is transmitted across a synaptic cleft by the release of a neurotransmitter from the axon terminal of a presynaptic neuron.
