During developmental years, T4 also is responsible for normal development of nerves and neurons. The catecholamine effect refers to the bodys response to stress, invoking the flight or fight response in the body.

This hormone also increases the catecholamine effect, the bodys sensitivity to adrenaline. There are health issues linked to low and high levels of this hormone in the body. Thyroxine is also known as T4, as the molecular structure consists of thyronine molecule with four iodine molecules.

How thyroxine affects the body

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.

Thyroxine is one of the main hormones secreted from the thyroid follicular cells. Within the body, thyroxine affects the bodys metabolism and has an effect on protein synthesis. It is also important for human growth and development, as it regulates bone growth and aids in the maturation of neurons.

The cause is unknown. Thyroid hormones are essential for physical and mental development so hypothyroidism during development or before birth and during childhood causes mental impairment and reduced physical growth. Hypothyroidism in adults causes a decreased metabolic rate. This

This response is due to the presence of adrenaline and noradrenaline in the body. The presence of thyroxine increases the bodys sensitivity to catecholamine compounds. An overactive or underactive thyroid can result in issues with T4 levels in the body.

Mar 23, 2015. The function of the thyroid gland is to take iodine, found in many foods, and convert it into thyroid hormones: thyroxine (T4) and triiodothyronine (T3). Thyroid cells are the only cells in the body which can absorb iodine.

May be caused by overactivity of the thyroid gland ( hyperthyroidism as in Graves' disease, inflammation of the thyroid or a benign tumour. Thyrotoxicosis can be recognised by a goitre which is a swelling of the neck due to enlargement of the thyroid gland. Other

What happens if I have too little thyroxine? Too little production of thyroxine by the thyroid gland is known as hypothyroidism. It may be caused by autoimmune diseases, poor iodine intake or brought on by the use of certain drugs. Sometimes,

Symptoms of thyrotoxicosis include intolerance to heat, weight loss, increased appetite, increased bowel movements, irregular menstrual cycle, rapid or irregular heartbeat, palpitations, tiredness, irritability, tremor, hair loss and retraction of the eyelids resulting in a staring appearance.
