Question
Chapter 15.5, Problem 17WDYL
Summary Introduction
To determine:
The possibility for the stimulation of adrenergic receptors to result in either vasodilation or vasoconstriction of the selected vessels of the blood.
Concept introduction:
There are cholinergic as well as adrenergic receptors. The signalling molecules like hormones or neurotransmitters are known as ligands as they get bound to the receptors. The ligands class, which bind to the receptors (adrenergic) in neurons is known as the monoamines or biogenic

1.can you tell me why do we choose sympathetic instead of para symapthetic. make it short and clear.
2.If we say sympathetic why do we choose pregangolic with ACH ? how can I know?
3. explain how is alpha beta thing relate. How do you choose vasoconstriction vs vasolidation?
please teach me a trick. make it short and claer please. I get so confused
Activation of α-adrenergic receptors in vascular smooth muscle stimulates (vasodilation or vasoconstriction). Give an example of an organ system where this occurs.
Why is it possible for acetylcholine to actually cause an increase in stroke volume, even though increased parasympathetic activity causes an overall decrease in cardiac output?
