An underactive thyroid gland, also known as hypothyroidism. The gland is not producing enough T4 (thyroxine) and T3 (triiodothyronine). These hormones control metabolism, so underactive thyroid symptoms include fatigue, mentally foggy, depression, weight gain, slow pulse, constipation, dry hair and skin and nails, even low body temperature. Menstrual irregularities and feeling cold easily can occur as well. It can be easily treated by taking thyroid hormone daily. A TSH level (thyroid stimulating hormone) should be run as well, and will be high unless the pituitary gland is failing.
triiodothyronine
No. Thyroxine is also called as tetraiodothyronine. So thyroxine has four iodine atoms and triiodothyronine has three iodine atoms.
Thyroid stimulating hormone, or TSH, stimulates the production of triiodothyronine and thyroxine. TSH comes from the pituitary gland.
Thyroxine and Triiodothyronine
thyroxine (T4) and triiodothyronine (T3)
thyroxine (T4) and triiodothyronine (T3)
No, it secretes thyroxine (T4) which is later converted into the biologically active triiodothyronine (T3) which in turn affects cells metabolic rate.
Mainly thyroxine, though it also secretes triiodothyronine (better call it T3, it's easier to spell) and calcitonin.
When the thyroid receives thyroid stimulating hormone (TSH) from the pituitary gland it produces triiodothyronine which is commonly referred to as T3, and thyroxine which is commonly referred to as T4. These hormones regulate the metabolism, protein synthesis and sensitivity to other hormones in the body.
The thyroid gland (tissue) produces thyroxine and triiodothyronine. When the thyroid receives thyroid stimulating hormone (TSH) from the pituitary gland it produces triiodothyronine which is commonly referred to as T3, and thyroxine which is commonly referred to as T4. These hormones regulate the metabolism, protein synthesis and sensitivity to other hormones in the body.
Thyroxine is the hormone.It is secreted by thyroid.
