The increase in parasympathetic tone usually results in increased excretion of water or increased volume of the secretions. The parasympathetic nervous system (PNS) controls homeostasis and the body at rest and is responsible for the body's "rest and digest" function. Asked by Wiki User. In these cases regulation is achieved by increases or decreases in the tone (firing rate) of the sympathetic fibers. FALSE. Answer. Through direct neural stimulation, the sympathetic division promotes many metabolic effects via hormone release. The 2 divisions have antagonistic effects on the internal organs … 3 4 5.
