During yоur semester mоdules, yоu leаrned аbout the importаnce of the Gut-Brain Axis, particularly a subfield of health known as psychoneuroimmunology that emphasizes the critical interaction of the psychological, neuroendocrine, and immunological processes in stress and illness. There is bi-directional communication between the gut and the brain. The gut communicates with the brain through four different channels: 1) the immune system, 2) the Central Nervous System;, 3) the Endocrine System, and the 4) Autonomic Nervous System. Describe how these 4 channels are involved in the gut-brain axis. 1. Immune System: (4 points) 2. Central Nervous System: (4 points) 3. Endocrine System: (4 points) 4. Autonomic Nervous System: (4 points)
