This hormone controls the growth of the body by stimulating the elongation of bones .
3. Luteinizing Hormone (LH) triggers ovulation and the development of the “ corpus luteum” In females. In males it stimulates the release of testosterone by the testes. B. A nterior pituitary releases 6 major hormones
Secretion of thyroxin is regulated by TSH, which is secreted by the pituitary gland.
Regulates the rate of metabolism in the body and is essential for normal physical and mental development.
A person who suffers from hypothyroidism has a lower metabolic rate, which can cause obesity and sluggishness.
The opposite condition, known as hyperthyroidism, occurs when the thyroid produces too much thyroxine. It can lead to excessive perspiration, high body temperature, loss of weight, and a faster heart rate
Lack of iodine in the diet will lead to lack of thyroxin secretion. This produces enlargement of the thyroid gland and is called Goiter.
Goiter - is the result of iodine deficiency in the diet.
Goiter = an overly enlarged thyroid, due to a diet deficient in iodide
Is a type of self-regulation associated with endocrine regulation.
It operates on the principle that the level of one hormone in the blood stimulates or inhibits the production of another hormone.
Ex : TSH regulates the secretion of thyroxin by the thyroid gland.
