• D. GABA

Answer 1

Answer: (A), (C)

The correct options are
A

Acetylcholine

C

Noradrenaline (Nor empnephrine)

There are two kinds of neurons involved in the transmission of any signal through the sympathetic system: pre-ganglionic and post-ganglionic. At the synapses within the ganglia, preganglionic neurons release acetylcholine, a neurotransmitter that activates nicotinic acetylcholine receptors on postganglionic neurons. In response to this stimulus postganglionic neurons—with three important exceptions—release norepinephrine, which activates adrenergic receptors on the peripheral target tissues.
