the inhibitory postjunctional alpha-adrenoceptors are more close to the alpha ( 2 ) -adrenoceptors , since they were stimulated predominantly by ephedrine and noradrenaline and inhibited by yohimbine.9 it has been shown that all alpha-adrenoceptor subtypes are to be found at every distance ( 0 to 70 cm ) from the ileocaecal valve and that they can be activated in the resting or in the acetylcholine-contracted states .
