What controls thyroxine?
Is a hormone secreted bx thyroid gland important in maintaing calcium and phosphate balance of the body,normal development of neurons,maintaining metabolic rate,important in growth of infants.
How does a negative feedback system work and Explain how negative feedback regulates the amount of thyroxine in the blood?
When the amount of a particular hormone in the blood is reaches a certain level, the endocrine system sends signals to stop the release of that hormone. "Pearson Education Inc."
How does adrenaline travel from the gland that secreted it to the target cells that it affects?
The previous answer was wrong, adrenaline does not travel in the blood stream as it is an excepion to the usual hormones secreted from the endocrine system.
How can Plasma glucose levels during exercise increase?
The blood glucose is used by the muscles during exercise. The level of the glucose in the blood drops down. This stimulates the secretion of the hormone called as glucagon. This glucagon is secreted by the alpha cells of the endocrine part of the pancreas.
What helps transport glucose to cells and decreases blood sugar?
thyroxine
The secretion of parathyroid hormone is controlled primarily by the?
concentration of blood calcium.
What hormone affects blood circulation?
hgh
Changes in blood osmotic pressure would most affect the secretion of?
ADH (Antidiuretic Hormone)
What type of stimulation controls parathyroid release?
Negative feedback between the parathyroid glands and the blood calcium concentrations regulates parathyroid hormone secretion. As blood calcium concentration drops, more parathyroid hormone is secreted; as blood calcium concentration rises, less parathyroid hormone is secreted.
Excess blood potassium hyperkalemia is removed by increasing secretion of the hormone which stimulates an increase in the secretion of potassium by cells within the?
aldosterone; cortical collecting duct
What type of reflex does the secretion of the hormone insulin in response to changes in blood glucose levels?
Endocrine reflex
Why is it important to test a baby's blood for the thyroxine level?
Thyroxine is the precursor to active thyroid hormone, which is essential for life. Thyroid hormone also plays an important role in brain development. A child with untreated low thyroid hormone (hypothyroidism) will develop a condition known as cretinism, which is marked by severe physical and mental abnormalities.
How is anti diuretic hormone secretion regulated?
Antidiuretic hormone (ADH) is regulated by the pituitary gland. The anitidiuretic hormone maintains blood pressure and controls incoming water through the kidneys

Regulation of the release of T3 and T4 from the thyroid gland is controlled by negative feedback?
When the level of the thyroxine increase, the level of the thyroid stimulating hormone decrease. So in turn the level of the thyroid hormone decreases. When the level of the thyroxine decrease, the level of the thyroid stimulating hormone increase. This in turn increase the level of the thyroxine. This explanation does not explain to how the level of the hormone is regulated at that particular level. But then this explanation satisfy most of the people.
