🤱 Oxytocin and the Milk-Ejection Reflex: A Positive Feedback Loop in the Body

Explore how oxytocin from the hypothalamus and posterior pituitary drives the milk-ejection reflex and labor contractions through rare positive feedback loops that amplify rather than dampen.

Medical Technology & Imaging Physics3DModerate60 FPS

This simulator visualizes how suckling stimulus, oxytocin pulses, and myoepithelial contraction reinforce one another in an escalating positive feedback loop, contrasted against how a typical negative feedback loop would behave.

🔬 What It Demonstrates

🎮 How to Use

Start or adjust the suckling stimulus and watch oxytocin levels and milk ejection rise together in pulses, then stop the stimulus to see how quickly the loop terminates without an internal brake.

💡 Did You Know?

Oxytocin's half-life in the bloodstream is only a few minutes, which is why the milk-ejection reflex can start and stop so quickly once suckling begins or ends.
