Αlpha Gamma Coactivation || Importance of Gamma Innervation to Muscle Spindle

Video Summary:
Αlpha Gamma Coactivation: α motor neuron stimulates extrafusal fibers and causes muscle contraction. This tends to make sensory endings on the muscle spindle go slack and thus insensitive. But simultaneous stimulation of gamma motor neurons causes contraction of intrafusal fibers of the muscle spindle. This helps maintain tension and thus preserves the sensitivity of the muscle spindle over a wide range of muscle lengths.

Thank you so much. My professor spent 30 min talking about gamma motor neurons and still failed to provide any clear, meaningful information. You managed to convey the info in 3 min 40 sec in a clear, linear manner. You rock!

[marioroman]

Very helpful, exactly what I was searching to understand this concept.

Why don’t our professors use images like yours to make the lesson easier? Nooo, they use such hard-to-understand photos, and the lesson becomes even more difficult 🙃.
