Using Sherrington's system, physiologists and anatomists search for specialised nerve endings that transmit mechanical data on joint capsule, tendon and muscle tension ( such as Golgi tendon organs and muscle spindles ), which play a large role in proprioception.

An excellent example of this is when a mechanical stimulus is applied to the monosynaptic input from muscle spindles to the motor neuron changes readily from one part of the step cycle to another, according to whether a subject is running or walking.

The primary sensory receptors for touch-position ( Meissner s corpuscles, Merkel's receptors, Pacinian corpuscles, Ruffini s corpuscles, hair receptors, muscle spindle organs and Golgi tendon organs ) are structurally more complex than those for pain-temperature, which are nerve endings.
44.
Tonic vibration reflex is evoked by placing a vibrator which in this case is typically an electrical motor with an eccentric load on its shaft on a muscle's tendon . 30 100 Hz vibration activates receptors of the skin, tendons and, most importantly, muscle spindles.
45.
H-reflex is analogous to the mechanically induced spinal stretch reflex ( for example, knee jerk reflex ) . " The primary difference between the H-reflex and the spinal stretch reflex is that the H-reflex bypasses the muscle spindle, and, therefore, is a valuable tool in assessing modulation of monosynaptic reflex activity in the spinal cord . " Although stretch reflex gives just qualitative information about muscle spindles and reflex arch activity; if the purpose of the test to compare performances from different subjects, H-reflex should be used.
