The neurotransmitter that is released by the axon of a sympathetic preganglionic neuron to communicate with the sympathetic postganglionic neuron is Acetylcholine. Acetycholine is the neurotransmitters released by the postganglionic neuron in sympathetic division. Acetycholine is responsible for the stimulation of muscles, including the muscle of the gastro-intestinal system. It is also found in sensory neurons and in the autonomic nervous system and has a part in scheduling REM sleep.
Explanation:
Evolution is a slow natural process occurring in living organisms which explains the formation of the diversity of organisms on Earth. In simple terms, evolution explains how life survived on Earth after the origin of life but it cannot explain the origin of life. However, modern evolutionary biologists are now trying to decode the origin of life through evolutionary evidence and support that earlier form of life originated in the large oceans around 3.5 billion years ago. These organisms are simple living unicellular organisms which later evolved into the eukaryotic organisms.
