In some forms of Hyperthyroidism, the thyroid gland (the target gland) releases far higher than normal amounts of thyroid hormone. Assuming that this form of the disease affects only the thyroid gland, you would expect levels of thyrotropin releasing hormone (TRH) released from the hypothalamus and thyroid stimulating hormone (TSH), released from the anterior pituitary to be_______ and ________, respectively.

Explanation / Answer

1. Answer:- True
Explanation:- The hypophyseal portal system is a system of blood vessels in the micro circulation, connecting the hypothalamus with the anterior pituitary.

2. Answer:- Releasing hormone
Explanation:- troph are releasing hormone.
Example- ACTH(Adrenocorticotropic hormone) stimulate adrenal cortex.

3. Answer:- TRH, TSH
Explanation:-The hypothalamus releases TRH (thyrotropin releasing hormone), which travels through a venous plexus to the anterior lobe of the pituitary gland and stimulates release of thyroid stimulating hormone, which in turn induces production of thyroxine (T4) by the thyroid gland.

4. Answer:- low,low
Explanation:- Thyroid-stimulating hormone (TSH) produced by the pituitary gland and TRH released by hypothalamus will be decreased in hyperthyroidism.
