It is one of the three primary germinal layers, the other layers being the mesoderm and the endoderm.The ectoderm develops the nervous system, external sensory organs as well as the hair and skin glands. The ectoderm itself consists of three separate parts: surface ectoderm, neural ectoderm and neural crest.hese cells also assist in the development of parts of the skeletal system, autonomic nervous system and hormone producing cells. This part of the ectoderm is located between the epidermis and neural tube.
