What influence does a hyperactive nervous system as seen in such conditions as Raynaud's disease, have on superficial circulation?
What will be an ideal response?
An activated sympathetic nervous system stimulates vasoconstriction in the superficial arterioles. This vasoconstriction will decrease blood flow to the skin and may lead to skin discoloration (cyanosis), cooling, and ischemic pain.
