Thyroxine hormone. over-secretion and under-secretion of thyroxine hormones.
Ever looked at most basketball players and asked, Are these humans or they are simply imported from another world?
Those tall guys you see or watch playing basketball are affected by the secretion of the Thyroxine hormone.
Thyroxine, also known as T4, is a hormone produced by the thyroid gland. It is a major regulator of metabolism, growth, and development. Thyroxine is made up of four iodine atoms and two amino acids. It is released into the bloodstream and travels to all parts of the body.
Thyroxine works by binding to receptors on cells. When it binds to a receptor, it activates a series of reactions that lead to increased metabolism. This includes increased production of heat, energy, and protein. Thyroxine also plays a role in the development of the brain and nervous system.
The production of thyroxine is controlled by the thyroid-stimulating hormone (TSH) from the pituitary gland. When TSH levels are high, the thyroid gland produces more thyroxine. When TSH levels are low, the thyroid gland produces less thyroxine.
Too much or too little thyroxine can cause health problems. Hyperthyroidism is a condition where the thyroid gland produces too much thyroxine. This can cause symptoms such as weight loss, anxiety, and heat intolerance. Hypothyroidism is a condition where the thyroid gland produces too little thyroxine. This can cause symptoms such as weight gain, fatigue, and cold intolerance.
Thyroxine can be replaced with medication if the thyroid gland is not producing enough of it. This medication is usually taken as a pill. Thyroxine replacement therapy is usually safe and effective. However, it is important to take the medication as prescribed and to have regular blood tests to monitor levels.
Here are some of the functions of thyroxine hormone:
- Regulates metabolism: Thyroxine helps to regulate the body’s metabolism, which is the process of converting food into energy.
- Promotes growth and development: Thyroxine hormone is essential for growth and development, especially in children and adolescents.
- Regulates body temperature: Thyroxine helps to regulate body temperature.
- Controls heart rate and blood pressure: Thyroxine helps to control heart rate and blood pressure.
- Maintains bone health: Thyroxine helps to maintain bone health by promoting the formation of new bone and preventing the breakdown of old bone.
- Regulates the nervous system: Thyroxine helps to regulate the nervous system by promoting the development and function of nerve cells.
If you have any concerns about your thyroid health, talk to your doctor. They can do a blood test to check your thyroxine levels and recommend treatment
