Indentify the division of the nervous system in which the neurons of the ENS are classified and indentify the type of neuron that directly stimulates the muscles of the digestive system.

The neurons of the Enteric Nervous System (ENS) are classified under the peripheral nervous system. The type of neuron that directly stimulates the muscles of the digestive system is the motor neuron. Motor neurons are responsible for carrying signals from the central nervous system to the muscles, causing them to contract and move. In the case of the digestive system, motor neurons control the movement of food through the gastrointestinal tract by stimulating the smooth muscle contractions that facilitate digestion and absorption.
