glabrous

Examples of glabrous in the following topics:

• Somatosensory Receptors

  • Merkel's disks are found in the upper layers of skin near the base of the epidermis, both in skin that has hair and on glabrous skin; that is, the hairless skin found on the palms and fingers, the soles of the feet, and the lips of humans and other primates.
  • They are found primarily in the glabrous skin on the fingertips and eyelids.
  • They are found in both glabrous and hairy skin.
  • Pacinian corpuscles, located deep in the dermis of both glabrous and hairy skin, are structurally similar to Meissner's corpuscles.

• Integration of Signals from Mechanoreceptors

  • Touch receptors are denser in glabrous skin (the type found on human fingertips and lips, for example), which is typically more sensitive and is thicker than hairy skin (4 to 5 mm versus 2 to 3 mm).
