18
Q

what are the 3 zones of the adrenal cortex

A

zona glomerulosa, fasciculata, and reticularis

19
Q

what is secreted from the zona glomerulosa?

A

aldosterone

20
Q

what is secreted from the zona fasciculata?

A

cortisol

21
Q

what is secreted from the zona reticularis?

A

DHEA or androgens

22
Q

what are the 2 main cells of the anterior pituitary?

A

basophils and acidophils

23
Q

where are basophils? what do they secrete?

A

In the lighter part of the anterior pituitary with darkly stained nuclei. They secrete TSH, ACTH, FSH, and LH

24
Q

where are acidophils? what do they secrete?

A

they are in the darker portion of the anterior pituitary. They have more lightly stained nuclei and release GH and PRL

25
Q

what are the cells of the posterior pituitary?

A

pitulcytes

26
Q

what do pitulcytes of the posterior pituitary release?

A

ADH and oxytocin

27
Q

what are the 2 types of cells in the parathyroid gland?

A

oxyphils and chief or secretory cells

28
Q

what do the chief cells look like and what do they secrete?

A

dark and they secrete PTH
