The nervous system develops from which of the following layer during embryonic development of animals?
Correct answer: B. Ectoderm
- A. Mesoderm
- B. Ectoderm
- C. Endoderm
- D. Mesoderm and Endoderm
Explanation
Option [A]Mesoderm gives rise to muscular,skeletal and reproductive systemsOption [B] After embryonic development the body layers[ ectoderm, mesoderm and endoderm] in most triploblastic animals are represented by the structures formed from them. The systems such as integumentary and nervous system develop from Option [C] Endoderm forms the lining of the digestive tract and forms other glands of the digestive system, such as the liver.Option [D] Mesoderm and Endoderm [same as above]

About Embryonic Development
Embryonic development begins after fertilization with cleavage and formation of the morula and blastula, followed by gastrulation and the establishment of germ layers. It includes organ formation, tissue differentiation and early growth, rather than the later increase in size associated with postnatal development.
