Principles of Neuroscience. Mechanoreceptors. how having the pain makes you feel. A. ``` this is the one responsible for the detection of physical distortion (pressure, touch, vibration). However, some studies clearly demonstrate that vagal afferents convey information about high intensity mechanical stimuli to the central nervous system. A variety of receptor typesembedded in the skin, mucous membranes, muscles, joints, internal organs, and cardiovascular systemplay a role. Nociception is a subcategory of somatosensation.
