2. OBJECTIVES
At the end of the seminar, students should
be able to
 List the secretion of pituitary gland
 Know the cell secreting them
 Know the action of hormone secreted
basically

3. INTRODUCTION

4. HORMONE SECRETION
ACTH
(adrenocorticotropics
hormone)
TSH (tyhroid
stimulating
hormone)
Prolactin
Growth
hormone
FSH (follicle stimulating
hormone) and LH
(luteinizing hormone)
Oxytoxin
Vasopressin
(ADH)

5. ANTERIOR PITUITARY
SECRETION
CHROMOPHILS
-brightly stain granule in cytoplasm-
CHROMOPHOBES
- Granules not
prominent-
Acidophilic
-stain acid dye-
(eosin)
(α-cell)
Basophilic
-stain basic dye-
(haematoxcylin)
(β-cell)
-
Mammotrophs
(lactotrophs)
Thyrotrophs -
Somatotrophs Gonadotrophs -
- Corticotrophs -
