Click and drag the terms on the left to accurately complete the sentences on the right. Not all terms will be used. Dual innervation describes a scenario in which a target organ has innervation from _________ division(s) of the ANS. If the divisions create opposite effects on the same target organ, it is called _________ innervation. If the divisions have complementary effects on the target organ or system, it is called _________ innervation. Since the parasympathetic division causes _________ and the sympathetic division causes _________ , this is an example of antagonistic innervation.

Answer the following questions to test your understanding of the preceding section: How can the sympathetic nervous system have contrasting effects in a target organ without dual innervation?
Describe examples of specific effectors dually innervated by the two branches of the autonomic nervous system and explain how each branch influences function in a given effector. Describe examples of effectors innervated by only the sympathetic branch or the parasympathetic branch of the nervous system and explain how that branch by itself influences function in a given effector. Contrast sympathetic innervation of the adrenal gland with sympathetic innervation of other effectors. Describe visceral reflex arcs, including structural and functional details of sensory and motor (autonomic) components.
