Endocrine Glands
1.
Hypothalamus
2.
Pituitary = Hypophysis
3.
Thyroid Gland: T3, T4
4.
Parathyroid Gland
Anterior Pituitary = Adenohypophysis
Posterior Pituitary = Neurohypophysis
Middle Lobe
= Pars Intermedia
Note: parafollicular cells produce calcitonin
Zona glomerulosa: Mineralocorticoid
Zona fasciculata: Glucocorticoid
Zona reticularis: Androgens
80% Epinephrine
Medulla: Catecholamine
20% Norepinephrine
α: Glucagon
β: Insulin
Δ: Somatostatin
