Endocrine Organs• Purely endocrine organs

– Pituitary gland– Pineal body– Thyroid gland– Parathyroid glands– Adrenal: 2 glands

• Cortex• Medulla

• Endocrine cells in other organs– Pancreas– Thymus– Gonads– Hypothalamus

Hypophysis(pituitary gland)

9

Two divisions:

• Anterior pituitary(adenohypophysis)

• Posterior pituitary(neurohypophysis)

The Pituitary secretes 9 hormones

1. TSH2. ACTH3. FSH4. LH5. GH6. PRL7. MSH

8. ADH (antidiuretic hormone), or vasopressin9. Oxytocin
