ENDOCRINE SYSTEM
1. Divide the cells of the adenohypophysis according to the staining properties. Name the
hormone of each cell type.
2. Describe the hypothalamo-hypophyseal portal system. Is it a venous or an arterial portal
system? How is the production of adenohypophyseal hormones regulated? Is there a negative
feedback loop?
3. What are Herring bodies? Which hormones do they contain?
4. Describe the embryonic development of the hypophysis.
5. How does the thyroid gland differ from the other endocrine glands (in terms of histological
structure)? What is the composition of colloid? What do the parafollicular (C-) cells produce?
6. Name the cells of the parathyroid gland. Which hormone do they produce? Which pharyngeal
pouches give rise to the parathyroid glands? Are they endodermal or ectodermal?
7. What is the brain sand (acervulus cerebri/corpora arenacea)? Where can we find it? Which
hormone is produced by this particular gland?
8. Which embryonic structures give rise to adrenal (suprarenal) gland?
9. Describe the morphology of the zones of the adrenal (suprarenal) cortex and types of
hormones produced there. Which hormones are produced in the adrenal (suprarenal) medulla?
