The anterior pituitary then releases thyroid stimulating hormone also called thyrotropin or simply TSH.

接着，垂体前叶分泌促甲腺激素，简称TSH。

If that's negative, diagnosis requires serum levels of FSH, LH, estrogen, prolactin, TSH and testosterone.

如果没有，要检测血清中的FSH、LH、雌激素、泌乳素、TSH和睾酮水平以进行诊断。

These Auto antibodies include thyroid stimulating immunoglobulins which bind to the TSH receptor on the follicular cells and imitate TSH.

这些自身抗体包括甲腺刺激性免疫球蛋白，它会与滤泡细胞上的TSH受体合并模仿TSH。

Diagnosing hyperthyroidism is done by measuring blood levels of TSH, T3 , and T4 .

甲亢的诊断是通过测量血液中的TSH、T3和T4水平来实现的。

In some cases it's because of a mutated TSH receptor that inappropriately keeps these follicular cells active.

有时这是因为TSH受体基因突变，不适当地让滤泡细胞保持活跃。

If it's due to a primary cause, TSH will be low, an unbound thyroid hormones will be high.

如果是原发性甲亢，TSH水平将会很低，未合的甲腺激素水平会变高。

TSH stimulates the thyroid gland, which is a gland located in the neck that looks like two thumbs hooked together in the shape of a V.

TSH刺激甲腺，就是位于颈部中央的腺体，形如两个拇指勾在一起的“V”字形。

If blood levels of TSH are normal or high, this points to a pituitary tumor which can be confirmed with an injection a thyrotropin-releasing hormone.

如果血液中TSH的水平正常或升高，则考虑垂体肿瘤，这可以通过注射促甲腺激素释放激素来确定。

This is because low thyroid hormone levels tell the hypothalamus to release more thyrotropin releasing hormone, or TRH, and tell the pituitary to release more thyroid stimulating hormone, or TSH.

这是由于低甲腺激素水平刺激下丘脑释放更多促甲腺激素释放激素，即TRH，并刺激垂体释放更多促甲腺激素，即TSH。

The cascade starts off with just a trickle, as TRH goes just a few millimeters to the anterior pituitary, where it hits receptors on cells there, causing it to release thyroid-stimulating hormone, or TSH, into the bloodstream.

这种级联从涓涓细流开始，TRH 只到达垂体前叶几毫米，在那里它击中那里细胞的受体，导致它向血液中释放促甲腺激素或 TSH。
