What Is Tactile Perception?

The sensation of the skin tactile sensor when it comes into contact with a mechanical stimulus is called tactile sensation. Contacts are scattered on the surface of the skin, and the contacts are of different sizes and irregular distribution. Generally, the fingertips are the most, followed by the head, the back and the calf, so the touch of the fingertips is the most sensitive, while the calf and back are the most sensitive It is relatively slow. If you touch the surface of the skin with slender hair, it can only trigger when some special points are touched.

Tactile

There are tactile bodies in the deep layer of the skin and sensitive nerve cells in the vertebra. When the nerve cells feel the pressure caused by the touch, they will immediately send out a tiny current signal, which will follow the nerve fibers to the brain. Feeling this touch, the brain can immediately tell the extent of the touch and the location of the signal.

Special tactile sensor

There are three types of special sensory sensations in normal skin, including Meissner bodies, Merkel touchpads, and Pinkus bodies. Tactile receptors are hair receptors in hairy skin and Meissner bodies in hairless skin.
