1

What are the layers of the adrenal gland?

Zona glomerulosa, zona fasciculata, and zone reticularis

2

What is the inner layer of the adrenal gland called

Medulla

3

What cells are located within the medulla?

Chromaffin cells

4

Catecholamines are produced in what layer of the adrenal gland?

Medulla

5

What hormone are chromaffin cells in the medulla responsive to?

ACh

6

Epinephrine and Norepinephrine are produced by what cells within the adrenal medulla?

Chromaffin cells

7

What layer of the adrenal gland produces androgens?

Zona reticularis

8

What hormones regulate the zona reticularis?

ACTH and CRH

9

What hormones are produced in the zona reticularis

DHEA

10

ACTH and CRH act on the zona reticularis and cause production of what type of hormones?

Cortisol

14

What hormone regulates the zona glomerulosa?

Angiotensin II

15

What embryological tissue is the posterior pituitary gland derived from?

Neuroectoderm

16

What hormones are released from the neurohypophysis (posterior pituitary)?
