The hormone thyroxine is released in response to a pituitary hormone called tsh. as thyroxine levels increase in the blood, they exert negative feedback on the release of tsh by the pituitary gland. what effect will this have on the release of tsh?

Negative effect on TSH release

Explanation:

Thyroxine hormone is secreted by Thyroid gland into the bloodstream. In its active form of triiodothyronine it plays an important part in metabolism, growth, brain development etc.

Release of thyroxine hormone is a part of hypothalamic-pituitary-thyroid axis and follows negative feedback. When the levels of thyroxine increases in the blood, it inhibits the release of TRH( Thyroid-releasing hormone) from hypothalamus which in turn inhibits the release of TSH ( Thyroid-stimulating hormone) from anterior pituitary. Decreased TSH inhibits the secretion of Thyroxine from thyroid gland.

thrombocytopenia, which is a deficiency in blood platelets, can cause bleeding and bruising in the dermis similar to senile purpura. other possible causes include: exposure to ultraviolet rays and aging skin are common causes of senile purpura. senile purpura may also be a sign of collagen loss in the skin and bones.
