Answer:
Thyroxine is the hormone secreted by the gland called Thyroid gland.
Over secretion of Thyroxine can lead to a disease called "Goiter"
Explanation:
→ There are different hormones secreted in our body by different glands.
→ One of those gland is Thyroid gland which is found in the neck region.
→ it's shape is like a butterfly.
→ It secrets thyroxine.
→ It controls the metabolism in our body.
→ if it is over secreted it can lead to 'goiter'.
Answer:
Explanation:
T4; tetraiodothyronine; thyroxin
What is thyroxine?
Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It is the inactive form and most of it is converted to an active form called triiodothyronine by organs such as the liver and kidneys. Thyroid hormones play vital roles in regulating the body’s metabolic rate, heart and digestive functions, muscle control, brain development and maintenance of bones.
How is thyroxine controlled?
The production and release of thyroid hormones, thyroxine and triiodothyronine, is controlled by a feedback loop system that involves the hypothalamus in the brain and the pituitary and thyroid glands. The hypothalamus secretes thyrotropin-releasing hormone which, in turn, stimulates the pituitary gland to produce thyroid stimulating hormone. This hormone stimulates the production of the thyroid hormones, thyroxine and triiodothyronine, by the thyroid gland.
This hormone production system is regulated by a feedback loop so that when the levels of the thyroid hormones (thyroxine and triiodothyronine) increase, they prevent the release of both thyrotropin-releasing hormone and thyroid stimulating hormone. This system allows the body to maintain a constant level of thyroid hormones in the body.
