GENERAL HISTOLOGY

Detailed explanation-1: -The primary role of the gut neurons is to move food through the digestive tract using similar signals as neurons in the brain. The gut neurons also serve roles such as sensing fullness, reacting to signals from immune cells and responding to the release of stress hormones, which cause the feeling of butterflies.

Detailed explanation-2: -The vagus nerve, also known as the vagal nerves, are the main nerves of your parasympathetic nervous system. This system controls specific body functions such as your digestion, heart rate and immune system. These functions are involuntary, meaning you can’t consciously control them.
