Sensation (psychology) - Senses and Receptors - Mechanoreceptors


Mechanoreceptors are sensory receptors which respond to mechanical forces, such as pressure or distortion. While mechanoreceptors are present in hair cells and play an integral role in the vestibular and auditory system, the majority of mechanoreceptors are cutaneous and are grouped into four categories: Slowly Adapting type 1 Receptors have small receptive fields and respond to static stimulation. These receptors are primarily used in the sensations of form and roughness. Slowly Adapting type 2 Receptors have large receptive fields and respond to stretch. Similarly to type 1, they produce sustained responses to a continued stimuli. Rapidly Adapting Receptors have small receptive fields and underlie the perception of slip. Pacinian Receptors have large receptive fields and are the predominant receptors for high frequency vibration.
