Where is golgi tendon organ located

So, when you hold a low-force stretch for more than seven seconds, the increase in muscle tension activates the GTO, which temporarily inhibits muscle spindle activity thus reducing tension in the muscle , and allows for further stretching. PNF is a stretching practice that promotes the response of neuromuscular mechanisms through the stimulation of proprioceptors in an attempt to gain more stretch in a muscle.

The pre-stretch contraction reduces muscle spindle activity within its associated muscle the muscle that is about to be stretched so that the brain more willingly accepts an increase in range of motion during the impending stretch.

The muscle spindles and GTOs go through this cycle to help you stretch safely and effectively. This is also the reasoning behind holding a stretch for seven to 10 seconds to allow the stretch to deepen. GTOs and muscle spindles work together through their reflexive actions to prevent injury.

These organs are composed of extrafusal muscle fibers that enter a funnel-like capsule that is filled with collagen fiber bundles. Nerve endings are entwined throughout these collagen fibers, and are triggered when tension in the muscle is transferred to the collagen fibers of the Golgi tendon organ. Golgi tendon organs are arranged in series with the extrafusal muscle fibers. This arrangement, along with the stiff structure of the Golgi tendon organ, renders this receptor more sensitive to muscle contraction than to muscle stretch.

The Golgi tendon organ is therefore specialized for monitoring the load or tension on a muscle, independent of length the job of the muscle spindle.
