Verified step by step guidance

Understand the concept of germ layers: In embryonic development, three primary germ layers form, which are the ectoderm, mesoderm, and endoderm. Each layer gives rise to different tissues and organs in the body.

Identify 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 the nervous system, including the neural tube.

Recognize the formation of the neural tube: During the process of neurulation, the ectoderm thickens and folds to form the neural tube, which will eventually develop into the central nervous system (the brain and spinal cord).

Differentiate between the germ layers: The mesoderm forms structures such as muscles, bones, and the circulatory system, while the endoderm forms the lining of the digestive and respiratory systems. The hypoderm is not a germ layer.

Conclude with the correct germ layer: Based on the roles of each germ layer, the neural tube is formed from the ectoderm.
