The Golgi tendon reflex is a protective mechanism that inhibits muscular contraction when excessive tension is detected in the tendon. During PNF stretching, activating the Golgi tendon organs through isometric muscle contractions can help to temporarily relax the muscle, allowing for a greater stretch to be achieved. This reflex helps to prevent injury by limiting the amount of force exerted on the muscle during stretching.
The Golgi tendon organ is a sensory receptor located at the junction of muscles and tendons. Its primary function is to monitor tension and force generated by muscle contractions. When muscle tension becomes excessive, the Golgi tendon organ sends signals to the central nervous system to inhibit further muscle contraction, thereby preventing potential injury. This reflex mechanism helps maintain muscle and tendon integrity during physical activity.
The Golgi tendon organ is located where muscle fibers of skeletal muscle meet tendons. Made up of strands of collagen, the organ also contains nerve tissue. The major function of this organ is to sense muscle tension when a muscle is contracted, sending signals to the brain about how much force is being exerted and where. This important sensory organ was discovered by and named after Camillo Golgi, an Italian physician who made numerous discoveries about the function of the human nervous system in the late 19th and early 20th centuries. Classified as a proprioceptive sensory receptor, the Golgi tendon organ belongs to a family of structures that send information to the brain about how joints are functioning, including the angles at which they are held, the length of the muscle at any given time and how much tension is placed on the joint or the muscle. At one time, it was believed that the Golgi tendon organ responded only to high levels of muscle tension in order to protect muscles from overexertion. The theory that they respond only to high tension is incorrect, though. Studies done in 1967 proved that the Golgi organ responds to all levels of muscle tension, from slight to extreme. When a reflex hammer is tapped below the knee, the Golgi reflex at that joint is being tested.
To answer your question in brief, the Golgi tendon organ is an involuntary mechanism that serves to maintain muscle tension and prevent injury. They are groups of fibres that wrap around the tendon, and have type Ib receptors that relay activity back to your brain. Upon activation, they increase their activity, which forces the shut down of the muscle contraction in order to prevent tearing of the muscle from excessive activation.
Two types of static stretching are active static stretching, where the individual uses their own muscles to hold a stretch position, and passive static stretching, where an external force such as a partner or prop is used to help stretch the muscle.
Golgi, or you can say Golgi body or the Golgi apparatus
The reflex of the Golgi tendon.
It's called the stretch reflex and involves muscle spindles which are sensorimotor organs located in skeletal muscle.
The inverse myotatic reflex, also known as the Golgi tendon reflex, is a protective mechanism that helps prevent muscle damage from excessive tension. When a muscle exerts too much force, the Golgi tendon organs, located at the junction of muscles and tendons, detect this increase in tension and send signals to the spinal cord. This triggers an inhibitory response, causing the muscle to relax and preventing potential injury. This reflex is crucial for maintaining muscle and tendon integrity during vigorous activities.

Muscle contraction
- Golgi tendon reflex - When there is too much tension on a muscle, the afferent sensory nerves send the information to the spinal cord which sends its information to the cerebellum where the information is used to adjust muscle tension. Simultaneously, the motor neurons of the spinal cord that innervates the contracting muscle are inhibited and the antagonistic muscles are activated. I believe (but am not certain sure) the term you're looking for is "deep tendon reflex" (aka "monosynaptic reflex"). When a muscle's tendon is suddenly stretched, receptors within the tendon send signals to cause the muscle contract, so it opposes the stretch. This is the reflex that's tested when you tap just below your knee and your foot swings out (a knee-jerk reaction :-) See Glossary of Terms in Spinal Cord Injury Research [sci.rutgers.edu/dynarticles/CareCureGlossary_20Jun02.doc ]
True
Golgi tendon organ
The internal tendon bulk is thought to contain no nerve fibres, but the epitenon and paratenon contain nerve endings, while Golgi tendon organs are present at the junction between tendon and muscle.
