The nervous system develops from which germ layer?
Answers
Answer:
Explanation:
A germ layer is a group of cells in an embryo that interact with each other as the embryo develops and contribute to the formation of all organs and tissues. All animals, except perhaps sponges, form two or three germ layers. The germ layers develop early in embryonic life, through the process of gastrulation. During gastrulation, a hollow cluster of cells called a blastula reorganizes into two primary germ layers: an inner layer, called endoderm, and an outer layer, called ectoderm. Diploblastic organisms have only the two primary germ layers; these organisms characteristically have multiple symmetrical body axes (radial symmetry), as is true of jellyfish, sea anemones, and the rest of the phylum Cnidaria. All other animals are triploblastic, as endoderm and ectoderm interact to produce a third germ layer, called mesoderm. Together, the three germ layers will give rise to every organ in the body, from skin and hair to the digestive tract
Answer:
the nervous system is derived from the ectodermal layer
Explanation:
all the part of our body related to brain including the spine, peripheral nerves and brain tooth enamel and the epidermis
during gastrulation the cells differentiate into outer ectoderm and inner endoderm ectoderm forms the nervous system and its associate
