The Gut-Brain Axis Flashcards
What is the Gut-Brain Axis?
The Gut-Brain Axis refers to the bidirectional communication network between the gastrointestinal tract and the brain.
True or False: The Gut-Brain Axis only involves neural communication.
False
Which systems are involved in the Gut-Brain Axis?

Fill in the blank: The Gut-Brain Axis plays a crucial role in __________ health.
mental
What types of signals are exchanged in the Gut-Brain Axis?
Neural, hormonal, and immune signals.
Multiple Choice: Which of the following is a key player in the Gut-Brain Axis?
Microbiota
What role do gut microbiota play in the Gut-Brain Axis?
They influence brain function and behavior through metabolic and immune pathways.
True or False: Stress can impact gut health and vice versa.
True
What is the enteric nervous system?
A complex network of neurons that governs the function of the gastrointestinal tract.
Fill in the blank: The vagus nerve is a key component of the __________ nervous system.
autonomic
Multiple Choice: Which neurotransmitter is primarily involved in mood regulation and is also affected by gut health?
Serotonin
What is the significance of the blood-brain barrier in the context of the Gut-Brain Axis?
It regulates the passage of substances between the bloodstream and the brain, influencing brain health.
True or False: Probiotics can positively influence mental health.
True
What are short-chain fatty acids (SCFAs)?
Metabolites produced by gut bacteria that can influence brain function.
Fill in the blank: The Gut-Brain Axis is implicated in various __________ disorders.
psychological
Multiple Choice: Which of the following conditions is associated with dysregulation of the Gut-Brain Axis?
Irritable Bowel Syndrome (IBS)
What is the role of the immune system in the Gut-Brain Axis?
It mediates inflammation and immune responses that can affect brain function.
True or False: Gut health has no effect on cognitive function.
False
What is the impact of diet on the Gut-Brain Axis?
Diet significantly influences gut microbiota composition and function, affecting brain health.
Fill in the blank: Chronic stress can lead to __________ changes in gut microbiota.
dysbiotic
Multiple Choice: Which of the following is a potential therapeutic approach targeting the Gut-Brain Axis?
Dietary modifications
What is the relationship between inflammatory bowel disease (IBD) and the Gut-Brain Axis?
IBD can lead to increased inflammation that affects brain function and mood.
True or False: The Gut-Brain Axis is only relevant to gastrointestinal diseases.
False
What are some psychological conditions linked to the Gut-Brain Axis?
Anxiety, depression, and autism spectrum disorders.
Fill in the blank: The Gut-Brain Axis is a key area of research in __________ medicine.
integrative
Multiple Choice: Which hormone is involved in the stress response that can also affect gut function?
Cortisol
What is the role of prebiotics in the Gut-Brain Axis?
They promote the growth of beneficial gut bacteria that can positively influence brain health.
True or False: The Gut-Brain Axis suggests a one-way communication from the gut to the brain.
False
What is the impact of antibiotics on the Gut-Brain Axis?
Antibiotics can disrupt gut microbiota and potentially affect brain function.
Fill in the blank: The Gut-Brain Axis is influenced by __________ factors such as lifestyle and environment.
extrinsic
Multiple Choice: Which type of diet is often associated with a healthier Gut-Brain Axis?
Mediterranean diet
What is neuroinflammation and its connection to the Gut-Brain Axis?
Neuroinflammation is inflammation in the brain that can be influenced by gut health and microbiota.
