What is the network of neurons embedded in the wall of the gastrointestinal system known as?

The network of neurons embedded in the wall of the gastrointestinal system is known as the Enteric Nervous System (ENS). This system is often referred to as the "second brain" because it can operate independently of the central nervous system while still communicating with it. The ENS is responsible for managing and coordinating the various functions of the gastrointestinal tract, including peristalsis (the wave-like muscle contractions that move food through the digestive system), enzyme secretion, and blood flow to the digestive organs.

The enteric nervous system contains a complex network of neurons, and it plays a crucial role in the autonomic regulation of digestive processes. It integrates sensory input from the gastrointestinal tract and coordinates appropriate motor outputs to ensure that digestion occurs smoothly. The ENS is unique in that it can function autonomously; for instance, it can continue to operate even if the connections to the brain or spinal cord are severed.

In contrast, the central nervous system consists of the brain and spinal cord and is primarily responsible for processing and integrating information from the entire body. The peripheral nervous system includes all the nerves outside the central nervous system, linking the CNS to the limbs and organs, but it does not specifically focus on the gastrointestinal tract. Lastly, the somatic nervous system is
