Are Golgi tendon organs Intrafusal or Extrafusal?
Extrafusal muscle fibers attach to bones with tendons which are a specific type of connective tissue. These tendons have proprioceptors called golgi tendon organs which lie at the ends of these extrafusal fibers.
What are GTO’s?
The Golgi tendon organ (GTO) (also called Golgi organ, tendon organ, neurotendinous organ or neurotendinous spindle) is a proprioceptor – a type of sensory receptor that senses changes in muscle tension.
Where are GTO located?
The GTO is located at the musculotendinous junction and is positioned in series with extrafusal muscle fibers and tendon.
What does the Golgi tendon reflex do?
The Golgi tendon reflex operates as a protective feedback mechanism to control the tension of an active muscle by causing relaxation before the tendon tension becomes high enough to cause damage.
What is the difference between Extrafusal and Intrafusal muscle fibers?
Muscles have receptors for stretch and force. Extrafusal muscle fibers comprise the bulk of muscle and form the major force-generating structure. Intrafusal muscle fibers are buried in the muscle, and they contain afferent receptors for stretch, but they also contain contractile elements.
What are the two primary actions of the Golgi tendon organ?
Two of these components—Golgi tendon organ (GTO) and muscle spindle—belong to the nervous system and function to influence movement. Two important proprioceptors that play a role in flexibility, the GTO and muscle spindle work together reflexively to regulate muscle stiffness.
Why are GTO called Goat?
The GTO was called “goat” because simple letter transposition to GOT with a long O is “goat”. Also, it pulled like one.
What is GTO and IGBT?
GTO stands for Gate Turn-Off Thyristor, IGCT stands for Insulated Gate Commutated Thyristor and IGBT stands for Insulated Gate Bipolar Transistor. The comparison between the three devices are derived with respect to symbol, characteristic, advantages, disadvantages and applications.
Who discovered Golgi tendon?

What is the difference between muscle spindles and Golgi tendon organs?
The key difference between muscle spindle and Golgi tendon organ is that muscle spindle is a sensory organ that senses the changes in muscle length and the rate of lengthening, while Golgi tendon organ is a sensory organ that senses the changes in muscle tension.
What happens when the Golgi tendon reflex is activated?
When the GTO is activated during contraction, it causes inhibition of the contraction (autogenic inhibition), which is an automatic reflex. When the GTO is activated during stretching, it inhibits muscle spindle activity within the working muscle (agonist) so a deeper stretch can be achieved.
What specific stimulus does the Golgi tendon organ detect?
The golgi tendon organ is a proprioceptor, sense organ that receives information from the tendon, that senses TENSION. When you lift weights, the golgi tendon organ is the sense organ that tells you how much tension the muscle is exerting.
What is the function of the Golgi tendon?
Understanding the Golgi Tendon Organ There are two primary proprioceptors responsible for maintaining proper muscle length and tone—the muscle spindle and the Golgi Tendon Organ (GTO). These two specialized cells work very efficiently together to control movement.
Do Golgi tendon organs have a high threshold of threshold?
Until 1967 it was believed that Golgi tendon organs had a high threshold, only becoming active at high muscle forces. Consequently, it was thought that tendon organ input caused “weightlifting failure” through the clasp-knife reflex, which protected the muscle and tendons from excessive force.
What is the other name of the Golgi apparatus?
The Golgi apparatus has multiple names such as Golgi complex or Golgi body. The name is given on the name of the scientist, who discovered the organelle, i.e. Camillo Golgi. It is found in all the eukaryotic cells, plants as well as animals. They are membrane-bound organelle present in the cytosol of the cell.
What happens if there are no Golgi fragments in the cell?
However, if there are no fragments there will be no Golgi apparatus. Without a Golgi apparatus the cell will not function. The Golgi apparatus is a critical member of the biochemical manufacturing and supply chain inside a cell.
