Both norad and adrenaline increases BP, but by different mechanism...
> Adreanaline increases BP by constricting blood vessles
>Noradrenaline Increases BP by increasing HR > Increase Impulse conduction > increase contraction > Increaseing volume expelled> thus increasing BP
> Noradrenaline causes: (i) constriction of the cutaneous vessels; (ii) constriction
of the vessels in skeletal muscle (adrenaline causes transient vasodilatation);
(iii) bradyeardia (adrenaline causes tachycardia); (iv) rise in both
systolic and diastolic pressures (adrenaline causes a rise in systolic pressure and
either does not effect or causes a slight fall in diastolic pressure).

∙ 13y agoThe updated names of these substances are epinephrine and norepinephrine. The difference between the two is a methyl group - CH3 - [ possessed by epinephrine ] - in its side chain.
These substances are hormones that are produced in, and secreted by, the adrenal medulla, and regulate heart rate and blood pressure.

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 are the two neurohormones found in sympathetic or adrenergic nerves?
Epinephrine or adrenaline, and non epinephrine or noradrenaline.
Adrenaline and noradrenaline?
Adrenaline and noradrenaline hormones are secreted in stress conditions. During this the blood vessels dilates and the heart rate increases. BUT actually the function of both the hormone is synergistic in raising the blood pressure. These also release glucose from liver and reinforce the effects of sympathetic system. In the absence of these hormones, the stress conditions are diminished.
