Transcript 
Posterior pituitary (pars nervosa)
A. Nerve axons with Herring bodies, nerve terminals, pituicytes (glial cells) 
1. Oxytocin  Uterus, mammary gland
2. ADH (vasopressin)
II. Anterior pituitary (pars distalis)
A. Acidophils
1. GH (Growth Hormone) – bone, muscle, fat
2. Prolactin – mammary gland, B cells in islet, lymphocytes
B. Basophils
1. ACTH  adrenal cortex  fasiculata, reticularis
2. MSH
3. FSH  Ovary (follicle), testes (sperm)
4. LH  follicle maturation, corpus luteum (ICSH  Leydig cells in testis)
5. TSH  thyroid  thyroglobulin  T3,T4  basal metabolic rate
III. Thyroid
A. Thyroglobulin (in colloid)  follicle cells  synthesis/breakdown to T3,T4  basal metabolic rate
B. Parafollicular cells  calcitonin  inhibits osteoclast  blood Ca2+
IV. Parathyroid
A. Chief Cells  PTH  stimulate osteoblast  activate osteoclast  blood Ca2+
B. Water Clear (Wasserhelle) – resting chief cells
C. Oxyphil  lots of mitochondria, unknown function
V. Adrenal cortex (steroid)
A. Zona glomerulosa – Aldosterone  kidney  Na+/H2O retention
B. Zona fasiculata – Glucocorticoids (cortisol)  anti-inflammatory, anti-mitotic, opposite of insulin
C. Zona reticularis – weak androgens
1. eosinophilic
VI. Adrenal Medulla
A. Dual blood supply
B. Pre-ganglionic sympathetic nerves synapse on chromaffin cells 
1. Norepinephrine
2. Epinephrine
3. Others
VII. Islets in pancreas
A. Blood Flow: BetaAlphaDelta
B. Alpha (outside) – glucagon  increased blood sugar (Fasting)
C. Beta (inside) – insulin  lowers blood sugar (Storage)
D. Delta – somatostatin
E. PP  pancreatic polypeptide
I.
