The Golgi tendon organ (GTO) (also known as Golgi organ, tendon organ, neurotendinous organ or neurotendinous spindle) is a skeletal muscle stretch receptor proprioceptor. It is situated at the interface between a muscle and its tendon known as the musculotendinous junction.[1] It senses muscle tension (whereas muscle spindles are responsible for detecting muscle length and changes in muscle length). It is innervated by type Ib sensory nerve fibers.[2]
It represents the sensory leg of the Golgi tendon reflex arc.
The Golgi tendon organ is one of several eponymous terms named after the Italian physician Camillo Golgi.
