Autonomic Nervous System2 Dr. Hussam Al-Humadi
1
Autonomic Nervous System (ANS)
2- Norepinephrine (NE) (Levarterenol)
Nor adrenaline
- It is the chemical mediator liberated by postganglionic sympathetic N.
ending & act directly on the effector cells.
- In therapeutic doses: ? and similar ?1 effect (on heart) but no ?2
Action of Nor adrenaline (NA)
C.V.S:
NA increase PR due to intensive vasoconstriction of most vascular bed
(including kidney via ?1), which lead to increase both Syst & Diast. BP
(with increase mean BP). This lead to compensatory vagal reflex by
stimulation to the baroreceptor reflex, which cause decrease contraction
of heart & decrease HR (called reflex bradycardia).
