Question

why Inner adrenal medulla is (ectodermal in origin)

Answer 1

The inner adrenal medulla is derived from neural crest cells, which are a type of ectodermal tissue. During embryonic development, these neural crest cells migrate to the site of the adrenal gland and differentiate into cells of the adrenal medulla. Therefore, the inner adrenal medulla is considered to be ectodermal in origin.
