catecholamines
What are drugs that mimic the sympathetic nervous system?

Which class of hormones is not stored in the secretory cell after being synthesized?
peptide hormones and catecholamines (epinephrine and norepinephrine)
Are catecholamines water insoluble?
Catecholamines are soluble in water.
What are the differences between catecholamines and non catecholamines?
catecholamines are chemical transmitters,polar compounds readily oxidized has catechol rings and amines such as dopamine nor-epinpherene and serotenie non- catecholamines with out catechol rings
Catecholamines are derived from what?
tyrosine
Is serotonin a catecholamine?
no serotonin is not a catecholamine. Catecholamines are dopamine, epinepherine and norepinepherine.
Do Noncatecholamines cross the blood-brain barrier more readily than catecholamines?
Yes, noncatecholamines cross the BBB more readily than catecholamines, because noncatecholamines are less polarized than catecholamines.
Catecholamines are produced by what cells?
Chromaffin cells.
What are the three catecholamines?
Epinephrine, Norepinephrine, and Dopamine.

What are the 3 components synapse?
acetylcholine catecholamines endorphins
What is the hormone that produce the cell of the adrenal medulla?
Composed mainly of hormone-producing chromaffin cells, the adrenal medulla is the principal site of the conversion of the amino acid tyrosine into the catecholamines adrenaline (epinephrine), noradrenaline (norepinephrine), and dopamine.
What releases catecholamines as a neurotransmitter?
it would be postganglionic sympathetic fibers
