Vasodilation refers to the widening of blood vessels. It results from relaxation of smooth muscle cells within the vessel walls, in particular in the large veins (called venodilators), large arteries, and smaller arterioles. The process is the opposite of vasoconstriction, which is the narrowing of blood vessels. When blood vessels dilate, the flow of blood is increased due to a decrease in vascular resistance. Therefore, dilation of arterial blood vessels (mainly the arterioles) decreases blood pressure.

An IQ of 123 is in the upper 5% of the population-however, even if you may be blessed with a high IQ, it comes down to what you plan to do to use it to its full capacity. A good IQ test is not age-dependent, so any score over 100 (which is average) would be, by definition, above average, irrespective of age. 2 people found this useful.
If it is 100-140 it's not a very good test and you're IQ could fall anywhere between those numbers, if it is a tight error band like 120 to 129 then it is a good test.Also, If you tell me the name of the test I can tell you if it was good or not.WISC and WAIS (the adult scale) are probably the most popular IQ test, and are both very good. They have strong validity and reliability. The error band on your IQ score will be small meaning your IQ is very close to your score.lso, If you tell me the name of the test I can tell you if it was good or not.
