Question

Why pituitary develop from two different germinal layers?

Answer 1

A germ layer is a primary layer of cells that form duringembryogenesis.[1] The three germ layers in vertebratesare particularly pronounced; however, all eumetazoans(animals more complex than the sponge) produce two or three primary germ layers. Some animals, like cnidarians, produce two germ layers (the ectoderm and endoderm) making them diploblastic. Other animals such as chordates produce a third layer (the mesoderm), between these two layers. making them triploblastic. Germ layers eventually give rise to all of an animal’s tissues and organs through the process of organogenesis.
