Ectodermal
Ectodermal
Ectodermal (pronunciation: ek-toe-der-mal) is a term used in the field of Embryology to describe one of the three primary Germ layers in the very early Embryo. The other two layers are the Mesoderm and Endoderm.
Etymology
The term "Ectodermal" is derived from the Greek words "ektos" meaning "outside" and "derma" meaning "skin". It literally translates to "outside skin", referring to its position in the developing embryo.
Definition
The Ectodermal layer is the outermost of the three germ layers, and it forms from the Epiblast layer of cells. It develops during the process of Gastrulation. The Ectodermal layer gives rise to various tissues and structures including the Epidermis, Nervous system, Tooth enamel, the lens of the eye, and some forms of Connective tissue.
