Dot Point 5 Flashcards
What is the gut-brain axis (GBA)?
The gut-brain axis (GBA) is a bidirectional communication system between the brain and the gut. The GBA plays a key role in regulating digestion, mood, stress, and even mental health.
What is the enteric nervous system (ENS), and how does it function?
A division of the autonomic nervous system that controls digestion.
Communicates with the CNS via the vagus nerve and gut microbiota.
How does the vagus nerve contribute to the GBA?
The vagus nerve is a crucial part of the gut-brain axis (GBA), acting as the major communication pathway between the gut and the brain.
What is gut microbiota, and what role does it play?
Gut microbiota are the trillions of microbes in the digestive system that help with digestion, immune function, and overall health.
A balanced gut microbiota supports immune function and controls inflammation, while an imbalance can contribute to diseases like obesity and diabetes.
How does chronic stress affect gut microbiota?
Chronic stress can harm the balance of bacteria in your gut. It can reduce the good bacteria and increase harmful ones. This can cause stomach problems, inflammation, and affect your overall health. Stress also releases cortisol, which can make the gut less healthy and cause more issues with digestion.
