Loop of vasodilation and vasodilator
How about a definition? Is this a chemical? A machine? A technique or a procedure? What is it?

Why Adenosine, mentioned in the table as an example of Calcium Chanel Blocker?
"Vasodilation" is a common misspelling or typo for: vasodilatation. Should this page be moved? http://www.websters-online-dictionary.org/va/vasodilation.html --Africantearoa (talk) 06:52, 20 August 2009 (UTC)
Vasodilators are synthetic or endogenous chemicals that act ultimately on the smooth muscle component of the vasculature and cause it to relax, which in medical terms translates to :
1. Increased caliber of arteries/veins
2. Lower blood pressure
3. Increased perfusion of target tissues
Cannabis is listed as a vasoconstrictor and a vasodialator, this doesn't seem to make sense
- Cannabis is generally speaking a vasodialator. However, some people experience panic attacks after ingesting cannabis, primarily of the eaten form, because the effect is too strong for them to handle. The strong effects of the cannabis lead to fear, which leads to vasoconstriction. This isn't really an effect of the cannabis though, more just a symptom of an individual's fear. It really shouldn't be listed as a vasoconstrictor.--Moeburn 05:50, 7 January 2007 (UTC)
Antihypertensive agents vs. peripheral vasodilators
- There are many different classes of anti-hypertensive drugs such as calcium channel blockers and diuretics. They do not affect vascular tone. Wisdom89 (T / C) 01:06, 23 April 2008 (UTC)
Being really picky here I know but..
"Adrenergic stimulation results in elevated levels of cAMP and protein kinase A, which results in increasing calcium removal from the cytoplasm. "
Seeing as the vast majority of calcium is removed to the SERCA, which is cytoplasmic, wouldn't removal from cytosol be more accurate?
Vasodilator vs venodilator
Could someone clarify vaso vs venodilator?
From what I understand, venodilators (dilate veins) decrease preload and vasodilators (dilate arteries?) decrease afterload. From this article it seems that venous dilation is part of vasodilation, but is that really true?
- Vasodilators increase the radius of arteries, and venodilators relax the smooth muscle in veins. The veinous system can adjust itself within some amounts to provide more or less arterial blood as needed for the rest of the body. Usually over an extra liter of blood is in the veins which can be put into the artery system by venoconstiction in the case of sudden blood loss. Bloomingdedalus (talk) 01:11, 21 June 2011 (UTC)
Small heat shock pathway
There is a need to add the hsp20 pathway of force suppression and vasodilation by cyclic nucleotide-dependent vasodilators. Hsp20 phosphorylation closely correlates with vasodilation. Regards GetAgrippa (talk) 01:37, 5 March 2011 (UTC)
Too many large paragraphs, too many lists, feel like cleaning?
