Verified step by step guidance1
Understand the concept of germ layers: Germ layers are the primary layers of cells formed during embryonic development. They differentiate to form all tissues and organs in the body.
Identify the three primary germ layers: Ectoderm, Mesoderm, and Endoderm. Each layer contributes to different parts of the developing organism.
Learn the role of the ectoderm: The ectoderm is the outermost germ layer. It is responsible for forming structures such as the skin, hair, nails, and importantly, the nervous system.
Differentiate between the germ layers: The mesoderm forms muscles, bones, and the circulatory system, while the endoderm forms the gastrointestinal tract and associated organs.
Conclude that the nervous system arises from the ectoderm: Based on the roles of each germ layer, the nervous system is derived from the ectoderm.
