How do thyroid hormones activate their target organs?
At the cellular level, THs bind to thyroid hormone receptors (TRs) that are members of the nuclear hormone receptor family. TRs act as ligand-activated transcription factors that bind to their cognate thyroid hormone response elements (TREs) in the promoters of target genes.Click to see full answer.

At the cellular level, THs bind to thyroid hormone receptors (TRs) that are members of the nuclear hormone receptor family. TRs act as ligand-activated transcription factors that bind to their cognate thyroid hormone response elements (TREs) in the promoters of target genes.Click to see full answer. Thereof, what is the target of thyroid hormones?In the case of TSH, the target organ is the thyroid gland. Clearly, robust control systems must be in place to prevent over or under-secretion of hypothalamic and anterior pituitary hormones. A prominent mechanism for control of the releasing and inhibiting hormones is negative feedback.Additionally, where are thyroid hormones stored? The synthesis and storage of thyroid hormones occurs between the follicular cells and the colloid (Box 3.5). Different follicles may be in different states of activity. Also to know, what organs does the thyroid affect? The thyroid gland is a small, butterfly-shaped gland located in the base of the neck just below the Adam’s apple. Although relatively small, the thyroid gland plays a huge role in our body, influencing the function of many of the body’s most important organs, including the heart, brain, liver, kidneys and skin.Does thyroid affect metabolism?When you have hypothyroidism, however, your thyroid gland doesn’t make enough of the hormone, and your metabolism slows down. A slower metabolism can make weight loss difficult, but it causes other symptoms too, such as fatigue and weakness.
