Parathyroid Gland Location - ANS Back side of thyroid; should have 4


Pancreatic Islet Cells Location - ANS Pancreas

,- ACTH
- Gonadotropins


Adrenal Hormones - ANS Cortisone, aldosterone


Thyroid Hormones - ANS T3, T4, Calcitonin


Parathyroid Hormones - ANS Parathyroid Hormone


Hypothalamus Hormones - ANS Growth; stimulates pituitary gland


Ovary Hormones - ANS Estrogen, progesterone


Testes Hormones - ANS Testosterone


Pituitary: What does it do - ANS -Thyroid Stimulating Hormone: tells thyroid to secret T3 and
T4
-Growth
-ACTH: Stimulates adrenal glands to secrete aldosterone AND cortisol
-Vasopressin (ADH): Limits diuresis and prevents excretion of water
-Gonadotropins- LH, FSH


ACTH - ANS stimulates adrenal glands to excrete aldosterone & cortisol


TSH - ANS tells thyroid to secrete T3 & T4


ADH/Vasopressin - ANS limits diuresis & prevents exertion of water

, Adrenal: What does it do - ANS Aldosterone
-Maintains extracellular (intravascular) volume
-Sodium/Potassium relationship


Cortisol
-CHO, fat, protein metabolism
-Stress, emotional stability
-Immune Function


Aldosterone - ANS - maintains intravascular volume
- sodium/potassium relationship
- regulated by RAAS system, serum potassium & ACTH


Cortisol - ANS - carb, fat & protein metabolism
- stress, emotional stability
- immune function
- also helps with water and sodium balance


Thyroid: What does it do - ANS T3 and T4 increase metabolism


Calcitonin- lowers Ca/Phos in serum


=Metabolism


More of T4 but T3 is potent


T3 & T4 - ANS increase metabolism
