At the effector end (nerve to effector organ junction) the transmitter is Nor Adrenaline. However, at the nerve-nerve junctions (ganglions) the transmitter is Acetyl Choline.
Norepinephrine
The adrenal medulla has many similarities with post-ganglionic sympathetic neurons, they release catecholamine because medullary cells are derived from the neural crest and, as such, are simply modified neurons. The adrenal gland releases epinephrine, norepinephrine and dopamine in response to neural not hormonal signals just like postganglionic neurons. The most significant different between adrenal medulla cells and true postganglionic sympathetic neurons is the absence of axons. The neurotrasmitter has become a hormone and is released into the blood.
The chemical most commonly found in both pre- and postganglionic synapses in the parasympathetic system is the neurotransmitter acetylcholine.
Anatomically, the adrenal medulla develops from neural crest tissue, and it is directly controlled by sympathetic NS. The medullary cells respond to this stimulation by releasing epineprhrine (80%) or norepinephrine (20%), which can act in conjunction with the sympathetic NS to elicit the fight-or-flight response to stressors.epinephrine, from the adrenal medulla.Norepinephrine/Noradrenaline working with Epinephrine/Adrenalineepinephrine and norepinephrine
The two integral parts of the autonomic nervous system are the sympathetic nervous system responsible for, "rest and digest" and the parasympathetic nervous system that is responsible for, "fight or flight".

Most of the blood vessels are innervated by sympathetic sympathetic adrenergic nerves.It releases norepinephrine which act as a neurotransmitter. The skin and few areas of body have both sympathetic cholinergic and parasympathetic cholinergic nerves which release acetylcholine,which act as a primary neurotransmitter.
Norepinephrine is a catecholamine with multiple roles including as a hormone and a neurotransmitter.Areas of the body that produce or are affected by norepinephrine are described as noradrenergic. One of the most important functions of norepinephrine is its role as the neurotransmitter released from the sympathetic neurons affecting the heart. An increase in norepinephrine from the sympathetic nervous system increases the rate of contractions
Synaptic vesicles store neurotransmitters to be released into the synapses. In the case of most motoneurons, this neurotransmitter is acetylcholine (ACh). The neurons that interface with the sympathetic nervous system, also technically motoneurons, release norepinephrine.

Neurotransmitters that cause a chemical change and hence generat impulse in the dendrites of adjacent neurons. most common neurotransmitter is acetylcholine
