inhibition of the antagonist muscle group is mediated by the muscle spindle. If the agonist muscle contracts, then the spindle fires, sending messages to the spinal cord causing the antagonist muscle to relax. PNF Stretching: Autogenic Inhibition. The golgi tendon organ is a nerve receptor found in tendons.This receptor fires when tension increases within the tendon. This tension can be due to stretch or contracting muscle.o achieve this the limb is place in painfree range and an isometric contraction is sustained. The limb is then moved into the new range. The hold-relax method of PNF stretching is facilitated by the golgi tendon organ to allow a reflexive relaxation of the muscle.
[Click to see a figure of a Golgi tendon organ from the text. , 2nd edition, by Purves et al. (2001). Just pay attention to panel A.] When the muscle contracts, the collagen fibrils are pulled tight, and this activates the Golgi tendon organ afferent (labelled Ib afferent in the figure).he muscle spindle is one type of proprioceptor that provides information about changes in muscle length. The Golgi tendon organ is another type of proprioceptor that provides information about changes in muscle tension. The figure schematizes the different components in a muscle spindle.
