Detailed cross-section diagram showcasing the mechanisms of CCK (cholecystokinin) hormone in appetite regulation and satiety signaling. In the foreground, a close-up view of the gut and digestive system, with the pancreas and intestines prominently displayed. Glowing pathways and receptors depict how CCK is released from the small intestine in response to food intake, then binds to receptors in the brain and gut to trigger feelings of fullness and meal termination. In the middle ground, a stylized schematic of the feedback loop between the gut and brain, with CCK highlighted as a key modulator. The background features a vibrant, colorful landscape of neurotransmitters, neural pathways, and the complex interplay of physiological processes involved in satiety and appetite control.
