Chemical diffusion
synapse is that junction through which impulse can be transmitted from one neuron to another.
They act at the end of a synapse. These are where in the nervous system (relay arc) a relay neurone meets a motor neurone. There is a gap called a synapse between these two neurones and so the only way to transmit the electrical impulse is through neurotransmitters which 'jump' across the gap whilist 'holding' on to the impulse.
It is most definitely a synapse.
neurons?
The impulse has to cross over a synapse to another neuron or an effector.
Neurotransmitters.
synapse
Nerve messages are called an impulse. Synapses are the space between two axons.
An impulse travels in one direction across a synapse, from the presynaptic neuron to the postsynaptic neuron. This ensures that the signal transmission in the nervous system is unidirectional.
At the synapse, the electrical impulse between the two neutrons at synapse set of chain chemical reactions which create a chemical impulse at the synapse.
synapse
It reaches the synapse and sends neurotransmitters to start a new impulse to the next neuron
