Proprioceptor
Proprioceptors are used to perceive the position and movement of the body in space and thus for proprioception . Through them, information about muscle tension , muscle length, joint position and movement reaches the cerebellum and the cortex , where it is processed unconsciously. The proprioceptors include the muscle spindle , the Golgi tendon organ , the Ruffini and the Vater Pacini body .
The muscle spindles are stretch receptors in the muscles . They are responsible for measuring muscle length and the rate of change in muscle length. They are very numerous in the muscles of the extremities, especially in the small muscles of the hands and feet. Above all, this enables the differentiated gripping function of the hand. The Ruffini and Vater-Pacini corpuscles are located in the joint capsules. They provide information about the position of the joints and their movements. The Golgi tendon organs are located in the tendons. They are excited by muscle contraction or muscle stretching.
