iodine deficiency
the amount of iodine available is insufficient to maintain normal blood levels of thyroid hormones.
low thyroid hormones level sensed by the hypothalamus & anterior pituitary gland.
the hypothalamus secretes thyroid releasing hormones & the anterior pituitary gland secretes thyroid-stimulating hormone.
receptors of thyroid gland cells are activated by high levels of TSH.
the cell of the thyroid gland enlarges in a futile attempt to produce more thyroid hormones
hypothyroid goiter
these are correct sequence
Add Answer to:
Sequence the steps from iodine deficiency to formation of a hypothyroid goiter. Iodine deficiency The amount...

1.The thyroid gland: shrinks when a person has goiter, which is caused by an iodide deficiency. produces thyrotropin-releasing hormone. sequesters iodide from the diet, and synthesizes thyroxine and T3. produces thyroid-stimulating hormone. stores thyroxine for up to months in the thyrotropes. 2. Increasing the concentrations of which of the following would cause the largest increase in calcium concentrations in the extracellular fluid? activating osteoblasts increasing the plasma concentrations of parathyroid hormone and calcitonin activating the chondrocytes increasing the plasma concentrations...
