Chemical Synapse
exocytosis
no
There is isotonic fluid inside the synapse. Neurotransmitter is released there inside the synapse.
The answer is NEUROTRANSMITTER.
neurotransmitter neurotransmitter neurotransmitter
no, synapse. node of ranvier is between axon and dendrites
replacing, decreasing, or enhancing the amount of neurotransmitter
Chemical synapses are specialized junctions through which neurons signal to each other and to non-neuronal cells such as those in muscles or glands. At a chemical synapse, one neuron releases a neurotransmitter into a small space (the synapse) that is adjacent to another neuron.
the synapse
The action of the excitatory neurotransmitter will increase, since its concentration in the synapse will rise.
Neurotransmitter stay for few milliseconds only in the synapse. The rate is difficult to define, but then the decay is most probably exponential decay. The acetylcholine is destroyed by the enzyme acetylcholinestarage. The noradrenaline is taken up back by the neuron, which has secreted it.
