The last types are Pacinian corpuscles, deeply located with fast-adapting characteristics (a single pulse).
In a glabrous skin, Pacinian corpuscles are deep-seated, whereas Meissner corpuscles are located nearer the surface.
Mechanoreceptors such as Meissner's corpuscles, Pacinian corpuscles
, Merkel's disks, and Ruffini endings are responsible for the detection of tactile input.
Other sensory receptors include free nerve endings, pacinian corpuscles
, ruffini corpuscles, taste buds, hearing receptors, and smell receptors (Figure 4-7).
The potential benefits of this approach "include preservation of the Pacinian corpuscles
to optimize sensation and preservation of the palmar fasciocutaneous attachment," Beth Costa, an occupational therapist at the center, said at the annual meeting of the American Burn Association.
Traditionally, these receptors are classified as muscle spindles (Ia and II fibers), Golgi tendon organs (GTOs) and joint afferents (GTOs, Ruffini endings, Pacinian corpuscles
, and free nerve endings).
However, some of the nerve endings, called Pacinian corpuscles
, are relatively deep - about 2 millimetres - under the skin, raising questions about how they could detect such subtle vibrations.
