Somatosensory Mechanoreceptors

State

Human skin carries several mechanoreceptor types tuned to different touch qualities: Merkel's disks for light touch, Meissner's corpuscles for touch and low-frequency vibration, Ruffini endings for stretch, Pacinian corpuscles for deep pressure.

Show

Merkel's disks, dense in fingertips, give the fine edge-sensitivity needed for tasks like typing.

Watch for

These receptors are unevenly distributed — glabrous skin carries far more than hair-covered skin.
