interoreceptors respond to stimuli within the body Mechanoreceptors respond to touch, pressure, vibration, stretch, and itchġ) Tactile receptors, which provide sensations of touch, pressure, and vibration. These receptors are stimulated by tension in the tendon they thus monitor the external tension developed during muscle contraction.ģ)receptors in Joint Capsuleswhich are richly innervated by free nerve endings that detect pressure, tension, and movement in the joint.
