thyroxine can trigger growth, temperature tolerance, or osmoregulation depending on the organism in which it is produced. which
larisa [96]

The primary hormone that the thyroid gland releases into the bloodstream is thyroxine. It is the inactive form, and organs like the liver and kidneys convert the majority of it into the active form triiodothyronine.

The body's metabolism, cardiac and digestive processes, muscle control, brain growth, and bone maintenance are all significantly regulated by thyroid hormones.

Hypothyroidism refers to the thyroid gland producing too little thyroxine. It could be brought on by autoimmune conditions, inadequate iodine consumption, or the use of specific medications. Sometimes there is no known cause. Untreated throxine before birth or during infancy can result in mental disability and stunted growth because thyroid hormones are crucial for both physical and mental development.

Adult hypothyroidism results in a slower metabolism. It may cause symptoms like weariness, a diminished ability to tolerate cold conditions, a low heart rate, weight gain, decreased appetite, impaired memory, sadness, muscle stiffness, and decreased fertility. For further details, read the article on hypothyroidism.
