These receptors are called Ruffini nerve endings, sometimes referred to as bulbous or Ruffini corpuscles. The sensation, which happens without warning, is usually painless and described as tingling or numbness, skin crawling, or itching. Furthermore, what are the functions of the skin? The skin has three main functions: protection, regulation and sensation. The dermis contains nerve endings, sweat glands and oil glands (sebaceous glands), hair follicles, and blood vessels. When these nerves are not functioning properly they can produce sensations such as numbness, pins-and-needles, pain, tingling, or burning. C. Digestion.

Ruffini Nerve Endings In addition to touch, pressure, and vibration, there are mechanoreceptors responsible for the sensation of the stretch of your skin, sustained pressure on the skin, and the perception of heat. The touch and pain receptors lie closes to the surface to the skin while the pressure receptors live deepest, thus requiring more stimulation to register an impulse.
