'''Epinephrine''' is produced by the adrenal glands. It is primarily involved in an overall activation of the sympathetic nervous system and is involved in the management of stress. '''Norepinephrine''' is also produced by adrenal glands and is involved in the initiation and maintainence of conciousness within the sympathetic nervous system. '''Dopamine''' is involved in motivation as well as love and addiction. '''Serotonin''' is involved in emotions, conciousness, sleep and thermoregulation. '''Melatonin''' is responsible for the regulation of onset of sleep and also for seasonal changes in the body such as winter weight gain and mating seasons. '''Histamine''' release results in increased gastric secretions, dilation of capillaries, constriction of bronchial smooth muscle and decreased blood pressure.

'''Norepinephrine''' is also produced by adrenal glands and is involved in the initiation and maintainence of conciousness within the sympathetic nervous system. Both types of neurotransmitter utilise α or β receptors and are metabotropic. '''Dopamine''' is involved in motivation as well as love and addiction.

The neuropeptide '''Acetylcholine (Ach)''' is primarily involved in skeletal muscle movement within the sympathetic nervous system and visceral movements as part of the parasympathetic nervous system. '''Nitrous oxide''' is involved in enlargement of the genital organs leading to erection.
