Neuron Synapse Diagram

Neuron Synapse Diagram. Synapse is a junction with a minute gap that separates two neurons (nerve cells), the basic unit of the nervous system in the brain. Most axons are covered in a lipid-based substance called myelin in the form of the myelin sheath that facilitates electrical conduction along the axon.

Example: acetylcholine (ACh) Binding of acetylcholine to its receptors on the postsynaptic cell opens up ligand-gated sodium channels.; These allow an influx of Na + ions, reducing the membrane potential.; This reduced membrane potential is called an excitatory. It is formed between the axon terminal of one neuron and the dendrites of the next neurons. Releasing of neurotransmitters through specific transport vesicles, called synaptic vesicles from one neuron to the adjacent connected neurons called exocytosis A resting neuron is an unstimulated neuron that is not presently generating an action potential.
