We have established that b-adrenergic receptors prevent the development of a stimulatory effect in response to the introduction of serotonin into the body. This action of b-adrenergic receptors is very strong - when serotonin is introduced into the body under conditions of blockade of b-adrenergic receptors, the stimulatory effect of dpk is 5 times greater than in infarcted animals. This is due to the fact that the serotonin introduced into the body activates not only 5HT receptors of serotonergic neurons and smooth muscles, but also presynaptic 5 - HT receptors of sympathetic nerve endings. Their activation leads to the release of norepinephrine, the latter inhibits contractions of the smooth muscles of the intestine. But the stimulating effect of serotonin on smooth muscle is stronger than the inhibitory effect of norepinephrine.
