From which germ layer do the epidermis and the nervous system originate? What are other organs and tissues made from that germ layer?

1 year ago

Epidermis and nervous system have the same embryonic origin: the ectoderm. The epidermal appendages (like nails, hair, sweat glands and sebaceous glands), the mammary glands, the adenohypophysis, the cornea, the crystalline lens and the retina are also derived from ectoderm.
