Explain the Function of Thyroxine and Triiodothyronine

Question

Examlex · Accepted Answer

The Answer is Thyroxine and triiodothyronine are both hormones produced by the thyroid gland and are essential for regulating metabolism and growth in the body.

Thyroxine, also known as T4, is the main hormone produced by the thyroid gland. It plays a crucial role in controlling the body's metabolic rate, as well as regulating heart and digestive function, muscle control, brain development, and bone maintenance.

Triiodothyronine, also known as T3, is a more potent form of thyroid hormone that is produced from thyroxine. It also plays a key role in regulating metabolism and energy production in the body.

If there is a hypersecretion of thyroxine and triiodothyronine, it can lead to a condition known as hyperthyroidism. This can result in symptoms such as weight loss, rapid heart rate, anxiety, tremors, and heat intolerance. In severe cases, it can also lead to complications such as heart problems and osteoporosis.

On the other hand, if there is a hyposecretion of these hormones, it can lead to a condition known as hypothyroidism. This can result in symptoms such as fatigue, weight gain, cold intolerance, dry skin, and depression. In severe cases, it can also lead to complications such as heart disease and infertility.

Overall, the proper function of thyroxine and triiodothyronine is crucial for maintaining a healthy metabolism and overall well-being in the body. Any imbalance in the secretion of these hormones can lead to significant health issues and should be addressed by a healthcare professional.
