Want to know:
Dual innervation in the autonomic nervous system refers to the presence of both sympathetic and parasympathetic nerve fibers that innervate the same organ or tissue. These two divisions of the autonomic nervous system have opposing effects on the same target, with the sympathetic division typically stimulating or activating the target, and the parasympathetic division inhibiting or suppressing it. This balance between the two divisions is crucial for maintaining homeostasis in the body, and any disruption in this balance can lead to various physiological and pathological conditions.
