Germ layer, Definition, Primary Layers, & Embryonic Development

Germ layer, any of three primary cell layers, formed in the earliest stages of embryonic development, consisting of the endoderm, the ectoderm, and the mesoderm. The germ layers form during the process of gastrulation and eventually give rise to certain tissue types in the body.
