  1. Hypothalamo-Hypophyseal Axis Prof. Dr. Bayram Yılmaz Yeditepe Üniversitesi, Tıp Fakültesi Fizyoloji Anabilim Dalı

  2. Relationship Between Hypothalamus and Hypophysis

  3. Hypothalamo-Hypophyseal Axis Coronal section of hypothalamus and 3rd ventricle

  4. HypothalamicHormones • Corticotropin -Releasing Hormone (CRH) • Thyrotropin -Releasing Hormone (TRH) • Growth Hormone -Releasing Hormone (GHRH) • Growth Hormone -Inhibiting Hormone (GIHor Somatostatin) • Gonadotropin -Releasing Hormone (GnRH) • Prolactin -Inhibiting Hormone (PIHor Dopamin)

  5. HypothalamicHormones-II Posterior Hypothalamus • Oxytocin • Vasopressin (ADH)

  6. Hypophysis (Pituitary Gland)

  7. Hypophyseal - Portal System

  8. Hypothalamo-Hypophyseal Axis

  9. Secretion Types

  10. Neurosecretion and Adenosecretion

  11. Pituitary Hormones and Their Functions There are 9 hypophyseal hormones

  12. Cell types in the anterior pituitary • These cells are highly specialized cells and usually secrete one type of hormone • These cells are named with respect to the hormone they release • Somatotropes“growth hormone” (somatotropin) • Lactotropes (mamotropes) prolactin. • Tyrotropes - TSH • Corticotropes - ACTH (corticotropin)

  13. Cell types in the anterior pituitary

  14. Hystology of anterior pituitary Histology of posterior pituitary
