Answer 1

The correct option is A 1.Medulla, 2. Cortex, 3. Catecholamines, 4. Steroids, 5. SNS, 6. ACTH

Adrenal gland develops from two germ layers, i.e. Ectoderm and Mesoderm. The ectodermal part is called Medulla and mesodermal part is called as Cortex. The chemical nature of the hormones of the ectodermal part is Catecholamines whereas the hormones of the mesodermal part are chemically Steroids. The ectodermal and mesodermal parts are stimulated by SNS and ACTH respectively.

Here, SNS stands for the sympathetic nervous system and adrenocorticotropic hormone (ACTH).
