Germinal Scutellum

The embryonic thyroid gland, also the germinal shield (from the Latin splenium - “layering”) is a structural element of the posterior part of the vertebrate brain. The parts of the brain have a unique arrangement. In reptiles and birds, its dorsal displacement is observed, in mammals and fish - abduction backward, and more primitively organized insects have an anterior rudimentary shield of the brain [1]. The germ plates and their structural organization largely determine the basic plan of the internal arrangement of the nervous system and its main structural elements - areas of the brain - and thus determine the formation of anatomical (receptor) in
