The gland that has a medulla derived from ectoderm and cortex from mesoderm is the adrenal gland.

Here's a breakdown:

* Adrenal Medulla: This inner part of the adrenal gland is responsible for producing catecholamines, particularly adrenaline (epinephrine) and noradrenaline (norepinephrine). It originates from neural crest cells, which are derived from the ectoderm.

* Adrenal Cortex: This outer part of the adrenal gland produces corticosteroids, including cortisol, aldosterone, and androgens. It originates from mesoderm.

So, while the adrenal gland appears as a single structure, its two parts have distinct origins and functions.
