A normal thyroid gland will help you maintain good health.
The thyroid gland is controlled by the pituitary that makes TSH -thyroid stimulating hormone - and that in turn controls production of thyroxine (T4) and triiodothyronine (T3 (liothyronine)).
The concentration of T4 is several fold the concentration of T3 (liothyronine).
These hormones essentially contribute to your well-being. There is good information on the web. ...Read more
Makes thyroid hormon: Hi. As the name implies, the thyroid gland makes thyroid hormone (actually secretes two: about 90% T4 and 10% T3). T4 (aka l-thyroxine, Synthroid, etc) is converted in the non-thyroid tissues to T3 (aka Cytomel, liothyronine), the hormonally active form. Take your thyroid hormone...the easiest, most perfectly treated endocrine disease! Good luck! ...Read more
With medication.: The adrenal glands produce androgenic hormones that can be blocked with medication. Aminoglutethimide, ketoconazole, abiraterone & tak-700 (orteronel) are examples, blocking the synthesis of steroid compounds in the glands. Other essential hormones that are blocked may need to be replaced. Surgical removal of both glands would also eliminate adrenal androgens, but it is not done for this purpose. ...Read more

I read that the pineal gland secretes melatonin at night, and serotonin during the day. Why would it secrete serotonin, and is it useful as a hormone?
Mela- vs Sero-tonin: Most of the serotonin in our body is in the GI tract. The brainstem's raphe nuclei (not the pineal gland) secrete serotonin in the central nervous system. Melatonin is derived from serotonin and is produced by the pineal gland. See a neurology or pulmonary sleep specialist to investigate your sleeping patterns. Take a detailed sleep log to the appointment. http://www.webmd.com/sleep-disorders/ ...Read more

Can you tell me about neuroendocrinology q! how come we can't make an inference of what hormones in the blood is in the brain?
Blood brain barrier: The blood brain barrier are cells that regulate what gets into the CNS. For example, insulin levels fluctuate widely in blood, based on food, but CNS insulin fluctuates much less. Also, many hormones act locally in brain. For example, serotonin, dopamine etc are high at the nerve synapse, but most is then taken up and plasma levels are very low. ...Read more
What is brain peptides?Are they different with brain proteins?Hormones produced by the brain are mostly peptide or protein? How about dopamine?
Peptide vs protein: A peptide is make of a few amino aicd building blocks but a protein is made of hundreds to thousands of amini acids. When a protein is degraded , it breaks up into smaller peptides. Dopamine is not a peptide since it is a modified single amino acid. Hormones from the brain are peptides but some such as acth come from a larger precurose protein. Great questions. ...Read more
