What is second brain ?

Explanation

1) Enteric nervous system is called as "second brain".
2) The neural apparatus of our digestive tract comprises of such a vast and complicated network of neurons.
3) Nervous system of gut is not is not only constricted to digestion or inflict the occasional nervous pang of hunger, but also mass of neural tissue is filled with important neuro transmitters.
4) Enteric nervous system is connected with big brain in our skull.
5) It determines our mental state and plays key role in certain diseases throughout the body.
6) The digestive tract is exposed to a large variety of psychochemical stimuli from the external world in the from of ingested food.
7) THe intestine act as a rich store of coordinated moments of its muscular apparatus along with neural apparatus.
8) Enteric nervous system consists of sheaths of neurons in the walls of our gut, which measures about 9 meters from the oesophagus to Anus. So it is called enteric nervous system.
9) Second brain involves in stimulating and coordinating breaking down of food, absorbing nutrients, and expelling of waste requires chemical processing, mechanical mixing and rhythmic muscle contractions.
10) It equipped with its own reflexes and senses, the second brain can control several gut functions often independently of the brain.
