    JRT - it's weird how one small thing that gets posted on the forum can stick in your head and drive you nuts. Guess #2 for Pro's other term is the myotatic stretch reflex......

    My understanding of the Golgi reflex: the receptors responsible for the stretch reflex are the muscle spindles that lie parallel to the muscle fiber and the Golgi tendon organs. The receptors are sensitive to stretch and their function is to help to protect a muscle from injury. As the muscle fiber stretches so does the spindle.

    The spindle responds to the speed of the stretch ie. if the stretch is quick and extreme, the muscle spindle responds by sending a signal to the spinal cord, which in turn send it's OWN signal for the muscle to contract (for it's own protection).

    The harder the muscle is stretched, the stronger the reflex contraction. But if the contraction or tension is great enough to risk muscle injury the contraction stops and the muscle finally begins to relax.

    The relaxation response to an extreme stretch is called autogenic inhibition (and is primarily dependant on the Golgi tendon organs - GTO)
