– A myriad of sensory receptors in different
layers of the skin provides us with sensations of
touch and pressure (merkels discs, pacinian
corpuscles etc. )
– Each receptor is stimulated by physical
deformation of the receptor itself or the area
surrounding it (mechanorepors)
– Distribution density of sensory receptors
throughout the body is not proportional. Higher
densities in areas that perform fine motor
movements. |
