The ectoderm is the outermost layer of the three primary germ cell layers of the embryo. (The other two layers are the mesoderm and the endoderm.) It is sometimes referred to as the ectoblast.

The epidermis, epidermic tissues, the nervous system, sense-related organs, and the mucus of the mouth and anus all arise from the ectoderm.
