ANATOMY

Detailed explanation-1: -The nervous system controls the digestive system by sending signals to the brain and organs. The brain sends signals to the stomach, intestines, pancreas, liver, and other organs through nerve cells called neurons. Some of these neurons pass on messages from one part of the body to another through electrical impulses.

Detailed explanation-2: -NERVE REGULATORS Extrinsic, or outside, nerves connect the digestive organs to the brain and spinal cord. These nerves release chemicals that cause the muscle layer of the GI tract to either contract or relax, depending on whether food needs digesting.

Detailed explanation-3: -Although the gastrointestinal (GI) tract possesses intrinsic neural plexuses that allow a significant degree of autonomy over GI functions, the central nervous system (CNS) provides extrinsic neural inputs that regulate, modulate, and control these functions.

Detailed explanation-4: -The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body. 01-Oct-2018
