Answer #1
  • The thyroid stimulating hormone (TSH) is secreted by the anterior pituitary . TSH regulates and synthesise the thyroid hormone i.e., T3(Tri-iodothyronin) and T4(Tetraiodothyronin).
  • Hypothalamus regulates the thyroid hormone secretion by controlling TSH secretion through thyrotropic releasing hormone(TRH) .
  • TRH is secreted in hypothalamus and from there it is transported to the anterior pituitary gland. After reaching the pituitary gland the TRH causes the release of TSH .
  • The thyroid hormone regulates their own secretion through the negative feedback mechanism .
  • Through the negative feedback mechanism they inhibit the release of TRH from the hypothalamus and TSH from anterior pituitary gland.

Gonadotropin-releasing hormone (GnRH) is synthesized in the hypothalamus and transported to the anterior pituitary. How does GnRH reach the anterior pituitary? Group of answer choices It is transported directly to the anterior pituitary by axons of the hypothalamic-hypophyseal tract. it is transported by axons to the posterior pituitary and diffuses from there into the anterior pituitary. It is released into the blood and travels through the systemic circulation before reaching the anterior pituitary. It is secreted into the hypophyseal portal...
