Spindle Nerve-Tendon Organ (Golgi Tendon Organ)

Nerve-Tendon Spindle (Golgi Tendon Organ) - see Tendon Spindle.

The tendon spindle is a specialized mechanoreceptor located at the junction of the muscle fibers and the tendon. Serves to monitor tension in the muscle and prevent damage due to excessive tension.

The tendon spindle consists of thin collagen fibers intertwining the tendon fibers. When the muscle and tendon are stretched, the spindle becomes deformed, which leads to the excitation of mechanoreceptors and the generation of nerve impulses. They enter the spinal cord and participate in reflex inhibition of the corresponding motor neurons, preventing excessive muscle tension.

Thus, the tendon spindle, or Golgi spindle, performs a protective function, preventing damage to muscle fibers and tendon rupture.

The spindle neurotendon, also known as the Golgi tendon organ (GTO), is a specialized structure in muscle that plays an important role in the control of muscle tone and posture. The GTO is located in the Golgi bursa, which is located between tendons and muscle fibers. This organ was discovered in 1952 by Italian biophysicist Massimo Golgi and subsequently received his name in honor of the researcher.

The spindle is a small, round structure consisting of a bundle of nerve fibers directed toward the epidermis through a tendon in a recess called the Golgi bursa. Essentially, it is an organic connection between muscle cells and the nerves that innervate the muscle. According to research, when a muscle moves in the direction indicated by the spindle, this organ is stimulated. Nerve fibers emanating from the spindle carry information about muscle movement to the central nervous system (CNS), where it is processed and interpreted. This information allows the brain to provide control over muscle tone and posture.

The GTO's function is not limited to controlling muscle tone, although that is its primary purpose. Substances present in the blood and central nervous tract may alter mechanical sensitivity in GTO. There is research into the influence of interactions between the GTO and other sensory organs such as joints and touch receptors. This allows the GTO to play an important role in maintaining balance and maintaining body stability.

Additionally, GTO is the subject of active research and
