1. Endogenous sulfur dioxide in low concentrations causes endothelium-dependent vasodilation . 2. When tissue metabolism increases, catabolic products accumulate leading to vasodilation . 3. However, it causes vasodilation and decreased vascular resistance during hypoxia. 4. Vasodilation is caused by the release of nitric oxide and adenosine.5. Vasodilation is a similar process mediated by antagonistically acting mediators.6. Through their role in vasodilation , prostacyclins are also involved in inflammation. 7. Thus sympathetic innervation to the coronary arteries ultimately causes vasodilation . 8. The neurons that control vascular vasodilation originate in the hypothalamus. 9. Vasodilation , dopamine, and circulatory factors are all implicated in migraine.10. Consequently, the concentration of cGMP decreases and the vasodilation is stopped.
