Question

How does the central nervous system regulate GI activity?

Answer 1

Regulation of GI activity by central nervous system:

1. The brain and spinal cord make up the Central Nervous System, which serves as our body's main processing centre.
2. The enteric nervous system is a network of nerves in the gut wall that is activated by the stretching of the GI lumen and the chemical composition of the chyme, both of which contribute to the production of food in the GI tract.
3. Nerve impulses are produced as a result of this trigger, which increase muscular and secretory function along the tract.
4. The enteric nervous system regulates blood flow, motility, electrolyte and water transport, and acid secretion in the gastrointestinal tract.
5. The smell, sight, and concept of food activates a component of the autonomic nervous system. The vagus nerve is a component of the CNS that sends and receives signals from and to the GI tract, promoting GI motility and secretion.
