The role of the nervous system in digestion is to provide electrical signals to initiate peristalsis. Peristalsis is the rhythmic contraction and relaxation of muscles in the digestive tract, which helps in the movement of food along the digestive tract from the mouth to the anus. These electrical signals are generated by specialized cells called the pacemaker cells, located within the walls of the digestive system.
To get this answer, you can refer to any basic physiology textbook or online resource that explains the functions of the nervous system and its role in digestion.
