My book says adrenergic implys noradrenaline is involved but some books say noradrenaline and adrenaline,which

Answer 1

In the whole autonomic nervous system there are 3 main hormones/neurotransmitters

1)Adrenaline
2)Noradrenaline
3)Acetylcholine

Adrenaline/Noradrenaline both stimulate the same receptors (alpha and beta adrenergic) but to different extents. (Think ADRENaline = ADRENergic. Both adrenaline and noradrenaline have ADREN in their name) AcetylCHOLINE stimulates CHOLINErgic receptors

All these transmitters are found in both the sympathetic and parasympathetic branches of the autonomic system

Answer 2

In the kidney, in the adrenal medulla it secretes adrenaline and noradrenaline, basically they are the positive and negative hormonal effect, it is your basic endocrine effect. one speeds up the heart rate (sympathetic nervous system) and the (parasympathetic nervous system) slows down the heart rate. Also some books have a lot of mistakes, so it is better to ask your instructor that is hopefully a doctor also. Do this when in doubt, but don't stop there always get a second opinion.

Answer 3

adrenergic effects are mediated by both.
the difference is one of them is stronger than the other.
one is a result of the methylation of the other.
there is a difference also between them in their presence in the adrenal medulla,so one of them is very high level in the blood in case of a tumour(eg pheocromocytoma) of the adrenal medulla,this is clinically important .
the problem is once you become a doctor you forget the basic stuff .
a good doctor never does.

Answer 4

adrenaline = epinephrine
noradrenaline = norepinephrine

"Adrenergic" is a term used to decribe the receptors that the above hormones bind to.
