How is thyroxine released in the thyroxine axis?
What will be an ideal response?
Like the SAM and HPA axis, the action for the thyroxine axis begins with the hypothalamus. The paraventricular nucleus of the hypothalamus responds to the demands on our systems to increase metabolism by releasing a polypeptide messenger releasing factor into the portal system of the anterior pituitary. This biochemical messenger prompts the anterior pituitary to release a compound called thyroid stimulating hormone (TSH). TSH then travels through the blood stream to the thyroid gland, a gland shaped like a butterfly that sits just below the larynx (the Adams apple is a good outer reference point for the larynx), prompting the release of thyroxine.
