Explain autonomic tone and its significance in controlling visceral function
What will be an ideal response?
Autonomic tone is the background level of activity in sympathetic or parasympathetic motor neurons under resting conditions. It provides a mechanism for fine control of visceral function because it allows a resting neuron to be less active or more active rather than to simply switch from off to on. This is particularly important when only one division innervates a visceral organ or when an organ (such as the heart) must be precisely controlled over a broad range of activity levels.
