[[Sensory_Pathways_-_Anatomy_%26_Physiology#Spinocerebellar_Tracts|'''Golgi tendon organs''']] are the sensory organs located within the tendon adjacent to the junction between the tendon and the muscle. These sensory neurons are interwoven into the collagen fibres within the tendon and are able to depolarise in response to excess changes in shape of the tendon. These golgi tendon organs are connected to inhibitory inter-neurons within the spinal cord which in turn, are connected to motor neurons innervating the muscle connected to the tendon. The result of this reflex arc is that if the sensory neurons detect tendon stretch that is excessive, the muscle will relax to reduce the load on the tendon.

===Withdrawal Reflexes===
The withdrawal reflex is behind the system that automatically withdraws any area of the body that experiences pain or discomfort. Examples of the withdrawal reflex would be an animal that experiences heat e.g. a cat walking onto an electric hob, chemical or cold stimuli amongst many others.
