1. Biology 3201 13.2 Endocrine glands (pituitary) p. 427-431

2. Pituitary is connected to Hypothalamus

3. Pituitary has 2 lobes

4. Control of the Anterior is different from the posterior

5. Posterior pituitary stores hormones for release

6. Where the pituitary fits in the big picture!!

7. Real pituitary

8. Portal system or vessels

9. Master Gland

10. Oxytocin Antidiuretic ACTH TSH HGH LH/FSH Prolactin

11. Gigantism 12 year old boy 6’ 5” Too much HGH in youth usually caused by tumour

12. Acromegaly enlarged hands, feet & face Too much HGH as adult Usually caused by tumour treat tumor or hGH blocking drugs

13. Pituitary dwarfism too little HGH as child tumor or missing pituitary note normal proportions

14. Genetic dwarfism note out of proportion big head regular body, short legs & arms

15. Prolactin stimulates lactogenesis Normally dopamine inhibits prolactin suckling stimultes nerves on nipple hypothalmus stimultes the production of prolactin Neuroendocrine reflex

16. Anti-diuretic hormone produced in Posterior Pituitary causes body to retain water too much salt detected by HYPO ADH produced too little salt detected less ADH produced Diabetes insipidus= insufficient Anti-diuretic produced

17. Oxytocin 1 function

18. Oxytocin 2nd function

19. Oxytocin; Affiliation hormone
