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.

Which reflex shows the least synaptic delay?
human physiology
What is the effector involved the patellar reflex?
In order to provoke the patellar reflex one must strike the patellar tendon with a tendon hammer (and only a tendon hammer, striking with an ordinary hammer is ill-advised). In other words, strike the region immediately below the patella.
How would you assess the calcaneal reflex?
you can observe a calcaneal reflex by striking the calcaneal tendon with the blunt side of a rubber hammer the calcaneal tendon is right above the heal on the backside of the foot, you can feel it easily
Does a Deep tendon reflexes are tested with a reflex hammer used to strike a joint?
yes
Is the Golgi tendon tendon organ voluntary or involuntary?
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.
What reflex causes muscles relaxation and lengthening in response to muscle tension?
The reflex of the Golgi tendon.
What reflex prevents a muscle from exerting too much tension?
It's called the stretch reflex and involves muscle spindles which are sensorimotor organs located in skeletal muscle.
What is the elbow reflex called?
you probably mean the biceps deep tendon reflex you probably mean the biceps deep tendon reflex
Is a deep tendon reflex tested with a reflex hammer striking a joint?
no you should not strike the joint ,but as the name suggest we should strike the tendon
Which reflex shows the least synaptic delay?
human physiology
The patellar knee jerk reflex is an example of?
Patellar reflex is an involuntary, deep tendon and myotatic reflex
What are the things that doctors use to check your knees?
Reflex hammer is used to check tendon reflex of the patellar tendon at the level of the knee. Arthroscopy is used to check the knee, internally.
What is the effector involved the patellar reflex?
In order to provoke the patellar reflex one must strike the patellar tendon with a tendon hammer (and only a tendon hammer, striking with an ordinary hammer is ill-advised). In other words, strike the region immediately below the patella.
What type of stimulation does a Golgi tendon organ respond to?
Muscle contraction
What is deep reflex?
The phrase deep reflex refers to being hit in the muscle tendon by something. An example is when the doctor checks your reflex on your knee.
What does the medical abbreviation DTR mean?
DTR stands for Deep Tendon Reflexes.Deep Tendon ReflexesOne expansion for the medical abbreviation "DTR" is "deep tendon reflexes."Deep Tendon Reflex.
What is the Reflex that causes reciprocal activation of antagonist muscle?
- 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 ]
