Ruffini Ending
slowly adapting,
low-threshold receptor,
which is constantly reactive during joint motion.
Additionally, these endings have
been found to react to axial loading and tensile strain
in the ligament, but not to perpendicular compressive
joint forces, revealing their importance in signaling
joint position and rotation, rather than direct pres-
sure. These characteristics are believed to be of
importance in the regulation of stiffness and prepara-
tory control of the muscles around the joint

Pacini Corpuscle
The Pacini corpuscle differs from the
Ruffini ending, in that it is a rapidly adapting, high-
threshold receptor sensitive to joint acceleration/de-
celeration that is able to sense mechanical distur-
bances occurring even at a distance

Golgi-like Receptor
Golgi-like ending is, there-
fore, silent in the immobile joint and only active at
the extremes of joint motion

Propriorecepece

'Intrafusal' muscle fibres contain 'muscle spindles,'
which signal passive, static, & dynamic muscle stretch


Golgi tendon organs signal tendon tension


Joint receptors are fast-adapting and signal joint angle
*The consensus is that muscle receptors (stretch receptors wrapped around the muscle fibres) play the major role in kinaesthesis

Simulace oddělení rukou bez přitahování 14-20cm

Test malá šance oddělit ruku pohybem v zápěsti pohyb je moc malej a jen se to prumeruje šance na uspech nic moc .
