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. It lies at the interface between a muscle and its tendon known as the musculotendinous junction also known as the myotendinous junction. [1]
Compared to Golgi type I neurons, these neurons' dendrites exhibit significantly less tufted dendrites. Two in the ten main dendrites protruded from the cell body and produced a small number of branches. [27] Golgi type II neuron generates dendro-dendritic connections with the main neuron in terminal aggregates termed synaptic nests.
Golgi's method is a silver staining technique that is used to visualize nervous tissue under light microscopy. The method was discovered by Camillo Golgi , an Italian physician and scientist , who published the first picture made with the technique in 1873. [ 1 ]
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 myotendinous junction between tendon and muscle. Tendon length varies in all major groups and from person to person.
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. [7] First, as a load is placed on the muscle, the afferent neuron from the Golgi tendon organ fires into the central nervous system.
One difference between the glans penis and the glans clitoridis is that the glans clitoridis packs nerve endings into a volume only about one-tenth the size of the glans penis. Therefore, the glans clitoridis has greater variability in cutaneous corpuscular receptor density (1-14 per 100× high-powered field) compared with the glans penis (1-3 ...
