Golgi tendon organs

Golgi tendon organs

tension sensors in tendons that send afferent impulses to the central nervous system, causing reflex inhibition to counterbalance whatever neural influences, voluntary and reflex, are stimulating the contraction. Thus they guard against excessive tension generation (with potential tearing of muscle or tendon). In less extreme circumstances, which are more common and probably more important, tendon organs interact with muscle spindles to control limb stiffness. First described in 1898 by Camillo Golgi, Italian histologist and Nobel prize winner.

The autogenic inhibition refers to a reduced contractile excitability of the stretched muscle, partially ascribed to an inhibition caused by Golgi tendon organs (CHALMERS, 2004).
It is true that group Ib axons carry information from Golgi tendon organs (in tendons); however, Ib axons do not provide information from joint receptors.
Golgi Tendon Organs are just that, tendon organs that are classified as Ib fibers.
Also, it is possible that the contract-relax PNF stretching applied on antagonist muscles results in a facilitator influence from both the Golgi tendon organ of the antagonists (PM and TL) and the muscles spindles of the agonists (LD and BC), a mechanism earlier proposed (20).
