When substances like acetylcholine and norepinephrine are released in the body‚ they tend to bind to receptors‚ tissues and neurons. These neurotransmitters transfer signals throughout the nervous system and stimulates action potentials in the postganglionic neurons. Receptors found on the ANS and PNS includes the cholinergic receptors‚ which consists of all sympathetic and parasympathetic preganglionic‚ sympathetic postganglionic and all parasympathetic postganglionic neurons. The cholinergic receptors

This hormone has so many effects on the body and its systems. It targets the stomach and small intestines and shuts them down‚ stopping digestion. Epinephrine is also responsible for the tension of the muscles and the increase of blood pressure.The body also produces a steroid hormone called glucocorticoid‚ which promotes
