Nervous tissue develops from ectoderm
WebN ervous tissue develops from the embryonic ectoderm, the layer covering the embryo that becomes the epidermis. The nervous tissue is composed of two cell types: neurons and glia. The main function of nervous tissue is the processing of information coming from the external and internal environments, and then triggers a response. WebAs the embryo develops, a portion of the ectoderm differentiates into a specialized region of neuroectoderm, which is the precursor for the tissue of the nervous system. Molecular signals induce cells in this region to differentiate into …
