Question
Chapter 15, Problem 20DYKB
Summary Introduction
To determine:
How sympathetic innervation regulates the vasodilation or vasoconstriction in the same blood vessels.
Concept introduction:
There are cholinergic as well as adrenergic receptors. The signaling molecules like hormones or neurotransmitters are known as ligands as they get bound to the receptors.

Students have asked these similar questions
what drives the enhanced sympathetic outflow to most other arterioles, the heart, and the veins and the decreased parasympathetic outflow to the heart?
Following a large increase in sympathetic output from the vasomotor center, what tissues will get less blood (increased resistance, reduced flow), and which ones will continue to get plenty of flow? How is sympathetic control of skeletal muscle arterioles different from other vascular beds?
Epinephrine is released during vigorous exercise. How would epinephrine cause vasoconstriction in the digestive organs but vasodilation in the heart?
