Create an image exactly like this. Perfect, professional.
A clean, professional medical diagram on white background showing MMC (Migrating Motor Complex) positive feedback mechanism. The diagram has a central oval/ellipse shape labeled "MMC" in large bold letters. Four arrows point toward the MMC oval from four different directions: 1. Top-left: An arrow pointing down-right toward the oval, labeled "Motilin" above it, with a "+" sign near the arrowhead. 2. Top-right: An arrow pointing down-left toward the oval, labeled "Serotonin" above it and "(5-HT)" to the right, with a "+" sign near the arrowhead. 3. Bottom-left: A double arrow (>>) pointing up-right toward the oval, labeled "Substance 'p'" below it. 4. Bottom-right: An arrow pointing up toward the oval, labeled "Neurotensin" below it. On the left side, vertically written text reads "POSITIVE FEEDBACK MECHANISM" with a bracket or brace connecting it to the oval. The style is clean diagram with dark blue/navy text and arrows on pure white background. Professional medical illustration style. Clear, readable sans-serif or mixed font. The oval is clearly drawn with a clean outline.
- MMC (Migrating Motor Complex) as the central oval
- Motilin and Serotonin (5-HT) above, with "+" stimulatory arrows pointing down into the oval
- Substance 'P' (bottom-left) and Neurotensin (bottom-right) with arrows pointing up into the oval
- POSITIVE FEEDBACK MECHANISM labeled on the left side
Positive feedback is just for motilin & 5HT. Give me a downloadable format. You can make it a bit creative and colourful.
