This neurotransmitter is utilized by both parasympathetic and sympathetic ganglionic neurons.
In a patient with heart failure, heart rate and contractile force is increased by giving epinephrine in combination with a _______ antagonist to avoid a compensatory reflex.
Increase or Decrease in BP: Baroreceptor mediated feedback control with B1 activation to increase HR and contractile force, a1 activation for vasoconstriction, and B1 activation fo
When norepinephrine is given exogenously, it is a potent __________ via activation of a1 receptors.
Fast or Slow: Hormones
Downregulation leads to _________. This is due to chronic agonist pressure on receptors and leads to loss of response over time.
More calcium in the neuron = more _______ release
A heart transplant patient given NE will have increased BP and heart rate because the ______ to the heart has been cut and there is no reflex.
Without adding a drug, ________ influences dominate vascular tone.
Upregulation leads to super-_________. This is produced via the absence of NT signal.
