Ectodermic refers to the outer layer of cells in a developing embryo that will eventually give rise to the skin, hair, nails, and nervous system. Some synonyms for ectodermic include epidermal, cutaneous, dermal, and integumentary, all of which refer to the various structures that make up the outer layer of the body. Other synonyms for ectodermic might include neural, because the nervous system is also derived from the ectoderm, as well as sensory or perceptual, because many of the external sensory organs, such as the eyes and ears, are derived from this layer. Overall, these synonyms help to describe the complex network of tissues and organs that originate from the ectodermic layer of the developing embryo.
