What are the steps that occur in adenohypophysis and the hormones that secreted in each part?

A
20
Q

What are the 6 hormones secreted hypothalamo-pituitary target organ? which are tropic and which are not tropic?

A
  1. Growth hormone (GH)
  2. (Insulin like growth factor) IGF
  3. Adrenocorticotrophic hormone (ACTH)
  4. Luteinising hormone (LH) FSH
  5. Thyroid Stimulating Hormone (TSH)
  6. Prolactin (PRL)
    all tropic except PRL is not tropic because it secretes milk
