Surface Ectoderm

The surface ectoderm (or external ectoderm) forms the following structures:

  • Skin (only epidermis; dermis is derived from mesoderm) (along with glands, hair, and nails)
  • Epithelium of the mouth and nasal cavity salivary glands, and glands of mouth and nasal cavity
  • Tooth enamel (as a side note, dentin and dental pulp are formed from ectomesenchyme which is derived from ectoderm (specifically neural crest cells and travels with mesenchmyal cells)
  • Epithelium of anterior pituitary
  • Lens, cornea, lacrimal gland, tarsal glands and the conjunctiva of the eye
  • Apical ectodermal ridge inducing development of the limb buds of the embryo.
  • Sensory receptors in epidermis

Famous quotes containing the word surface:

    A society which allows an abominable event to burgeon from its dungheap and grow on its surface is like a man who lets a fly crawl unheeded across his face or saliva dribble unstemmed from his mouth—either epileptic or dead.
    Jean Baudrillard (b. 1929)
