The surface ectoderm develops into the following structures:
- Skin (only the epidermis; the dermis is derived from the mesoderm) (along with glands, hair, and nails)
- The epithelium of the mouth and nasal cavity
- The glands of the mouth and nasal cavity, namely the saliva glands and the mucosal glands
- Tooth enamel (as a side note, dentin and dental pulp are formed from the ectomesenchyme, which is derived from the neuroectoderm (specifically neural crest cells, and it travels with mesenchymal cells)
- The epithelium of the anterior pituitary gland
- The lens, cornea, lacrimal gland, tarsal glands, and the conjunctiva of the eye
- The apical ectodermal ridge, which induces the development of the limb buds of the embryo
