Autonomic System Reactions Caused by Excitation of Somatic Afferents: Study of Cutaneo-Intestinal Reflex
Somatic responses in the body are always accompanied by reactions involving the autonomic nervous system. Any active or passive muscle movement is assisted by cardiovascular changes; painful stimuli applied to the skin or the muscle also produce changes in blood pressure and heart rate. These autonomic changes are not limited to cardiovascular changes only but also occur in other organs, such as the bladder, stomach or intestine. Thermal application, massage or gentle rubbing of the skin and the muscle are often used to relieve visceral discomfort, presumably because these sensory inputs from the cutaneo-muscular tissues affect autonomic innervation to the viscera.
