🦾 The Golgi Tendon Organ: How Muscles Protect Themselves from Excessive Force

Explore how Golgi tendon organs sense muscle tension and trigger the inverse myotatic reflex to prevent injury and fine-tune everyday movement.

Neuroscience & Biophysics3DModerate60 FPS

This simulator shows how tension at a muscle-tendon junction is detected by a Golgi tendon organ, converted into Ib afferent firing, and can trigger autogenic inhibition of the same muscle through a disynaptic spinal reflex.

🔬 What It Demonstrates

🎮 How to Use

Increase the simulated muscle load or contraction force with the controls and watch how Ib afferent firing rate rises, then observe the inhibitory reflex engage and reduce motor output once tension crosses the protective threshold.

💡 Did You Know?

A single Golgi tendon organ typically monitors the tension produced by only a small group of muscle fibers, so a muscle contains many GTOs sampling force from different regions rather than one central sensor for the whole muscle.
