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
