Which mechanoreceptor is located deeper in the skin and responds continuously to stimulation and is associated with perceiving s
Eva8 [605]

The mechanoreceptor that is located deeper in the skin and responds continuously to stimulation and is associated with perceiving stretching of the skin is called Ruffini corpuscle.

Mechanoreceptor is a sensory receptor that responds to mechanical pressure. They are connected with sensory neurons that convert this mechanical pressure into electrical signal. It is of four types-

1. Merkel corpuscles- detect pressure and roughness on skin.

2. Ruffini corpuscles- detect deep tension in skin, skin stretch.

3. Meissner corpuscles- perception of light touch and slip on skin.

4. Pacinian corpuscles or Vater-panician corpuscles- detect rapid vibrations.

When these receptors sense a stimuli they gets excited and generates an impulse that travels through the nerve cells into the brain.
