Denning [Date] [Course title]
, Function of the hypothalamus - Answer: Interface between nervous system and endocrine system;
controls homeostasis
How are the hypothalamus and anterior pituitary connected? - Answer: by the hypophyseal portal
system
Describe the path of the hypophyseal portal system - Answer: RHs and IHs are made by neurosecretory
cells (in hypothalamus)
--> diffuse into primary capillaries (in hypothalamus)
--> through hypophyseal portal veins (in infundibulum)
--> to secondary capillaries (in anterior pituitary)
--> RHs and IHs stimulate/inhibit anterior pituitary to regulate release of hormones
Name the 6 hormones produced by the anterior pituitary - Answer: 1. hGH (Human Growth Hormone)
2. Prolactin (PRL)
3. Thyroid Stimulating Hormone (TSH)
4. Adrenocorticotropic Hormone (ACTH)
5. Follicle Stimulating Hormone (FSH)
6. Luteinizing Hormone (LH)
How are the hypothalamus and posterior pituitary connected? - Answer: by neurosecretory cells (the
hypothalamo-hypophyseal tract)
What two hormones does the hypothalamus make? - Answer: 1. Oxytocin (OT)
2. Antidiuretic Hormone (ADH)
What happens to OT and ADH after they're produced in the hypothalamus? - Answer: They go through
the hypothalamo-hypophyseal tract to be stored in and released by the posterior pituitary.
What is the middle part of the thyroid called, which connects the two lobes? - Answer: isthmus
