Lower levels of T3 and T4 in the blood or lower metabolic rate serve as signal and stimulate the release of thyrotropin-releasing hormone (TRH) from the hypothalamus. The TRH stimulates the anterior pituitary gland to release thyroid-stimulating hormone (TSH) which in turn makes the thyroid gland to release the thyroid hormones.
The elevated levels of thyroid hormones inhibit the release of TRH from the hypothalamus and that of TSH from the anterior pituitary gland.
Hence, the cells of hypothalamus and anterior pituitary gland would be inhibited by the binding of thyroid hormone to regulate the release of these hormones by a negative feedback mechanism.
The cells that are inhibited by THE binding will be found in the anteriorpituitary, and hypothalamus gland
Explanation:
Triiodothyronine (T3), and thyroxine (T4) are the two hormones present in blood. The lower level of these hormone stimulates the hypothalamus for the release of TRH (thyrotropine releasing hormone), which in turn stimulates the anterior pituitary gland for the release of TSH (thyroid stimualting hormone), due to which thyroid gland releases the thyroid hormone.
Likewise, the increased level of thyroid inhibits the release of TRH, and TSH from their respective glands. And this is how, the cells of anterior pituitary, and hypothalamus gland would be inhibited.
When cell divides, the DNA will replicate in the parent cell or make copies of itself and this will make the chromatics to split or divide in order to create a new cell or daughter cell which contain the exact same DNA. The daughter cell then pass these DNA to subsequent generations, when it also undergo cell division and the dna is been replicated
Answer:External respiration occurs in the lungs where oxygen diffuses into the blood and carbon dioxide diffuses into the alveolar air. Internal respiration occurs in the metabolizing tissues, where oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells.
