- Skin (only epidermis; dermis is derived from mesoderm) (along with glands, hair, and nails)
- Epithelium of the mouth and nasal cavity and glands of the 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 mesenchymal 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.
