Calcitonin , kuj tseem hu ua thyrocalcitonin, cov protein hormone synthesized thiab zais cia hauv tib neeg thiab lwm yam tsiaj txhu feem ntau yog los ntawm cov kab mob parafollicular (C cells) hauv cov thyroid. Nyob rau hauv cov noog, ntses, thiab lwm yam uas tsis yog tsiaj vertebrates, calcitonin hmoov yog zais cia los ntawm cov cell ntawm glandular ultimobranchial lub cev.
Tom qab ntawd, ib tus tseem yuav nug, ua li cas calcitonin tso tawm?
Calcitonin yog ib yam tshuaj hormones ua hauv tib neeg los ntawm cov kab mob parafollicular (feem ntau hu ua C-cells) ntawm cov qog qog. Yog li ntawd, inhibition ntawm osteoclasts los ntawm calcitonin hmoov ncaj qha txo cov calcium tso tawm rau hauv cov ntshav.
Tsis tas li ntawd, kev ua haujlwm ntawm cov tshuaj hormone calcitonin yog dab tsi? Calcitonin yog ib yam tshuaj uas C-cells hauv cov thyroid caj pas tsim thiab tso tawm. Nws tawm tsam qhov kev txiav txim ntawm parathyroid hormone, pab tswj cov ntshav calcium thiab qib phosphate.
Yooj yim li ntawd, PTH tawm qhov twg?

Calcitonin ntau dhau ua dab tsi?
Yog ntau dhau calcitonin tau pom hauv cov ntshav, nws tuaj yeem yog ib qho cim ntawm hom qog noj ntshav qog noj ntshav hu ua medullary thyroid cancer (MTC). Qib siab kuj tseem yuav yog ib qho cim ntawm lwm cov kab mob thyroid uas tau ua rau koj muaj kev pheej hmoo siab dua kom tau txais MTC.

Qhov reabsorption thiab tso zis tawm hauv lub raum nyob qhov twg?
Reabsorption. Reabsorption yuav siv qhov chaw feem ntau nyob hauv qhov sib thooj sib sib zog nqus tubule ntawm nephron. Yuav luag tag nrho cov dej, piam thaj, potassium, thiab cov amino acids poob thaum lub sijhawm glomerular pom rov ua cov ntshav los ntawm lub raum tubules

Yuav muaj dab tsi tshwm sim thaum cov thyroid tso tawm calcitonin?
Calcitonin raug tso tawm los ntawm cov thyroid caj pas yog tias cov calcium hauv cov hlab ntsha siab. Calcitonin txo qis cov calcium thiab phosphorus hauv cov ntshav. Nws ua qhov no los ntawm kev ua haujlwm qeeb ntawm cov cell pom hauv pob txha, hu ua osteoclasts. Cov hlwb no ua rau calcium tso tawm thaum lawv 'huv' pob txha
