HN2.H1.3 +D1 Tongue - Ventral Surface Epithelium

Tongue - Ventral Surface Epithelium:

  • On the inferior surface of the tongue, the stratified squamous epithelium is thinner than is found on the superior surface
  • Normally, this surface is not subject to excessive wear and tear as results when the tongue is involved with rasping; as the inferior surface of the tongue moves over the floor of the mouth its passage is normally aided by the lubricating effects of saliva
