Sometimes the effects of sympathetic stimulation can be contradictory in the same types of tissue. For example, in the arterioles of the GI tract, sympathetic stimulation causes constriction while arterioles of skeletal muscle can dilate in response to sympathetic stimulation. What mechanism explains these opposite effects?

Neurotransmitter & Receptors

Explanation:

A neurotransmitter can typically tie to and initiate various diverse receptor proteins. Regardless of whether the impact of a specific neurotransmitter is excitatory or inhibitory at a given neurotransmitter relies upon which of its receptor(s) are available on the postsynaptic (target) cell In spite of the fact that the normally happening neurotransmitter ties to the entirety of its relating receptor types, the diverse structure of these receptors implies that a few medications tie more promptly to one kind of receptor than another. This is perfect for accomplishing one explicit medication activity while limiting reactions. And, it is useful for widening the aviation routes in the treatment of asthma, while having a lot more vulnerable impact on the heart, thus limiting undesirable impacts, for example, tachycardia (expanded pulse).Hence,the correct answer is "different receptors for the same neurotransmitter".
