机体激素含量的相对稳定对维持稳态有重要作用。

(1)内分泌腺没有导管,分泌的激素           __  。因此,临床上可通过抽取血样来检测内分泌系统的疾病。某甲状腺功能障碍患者,检测到体内有一种促甲状腺激素(TSH)受体的抗体,该抗体阻断TSH的效应,则该患者血液中TSH含量比正常值    __    。另一甲状腺功能障碍患者,下丘脑功能正常,血液中TSH和甲状腺激素(TH)含量明显低于正常值,为诊断病因,静脉注射TSH后,TH含量明显升高,表明该患者      __  部位发生了病变。

(2)下丘脑的         ____ 受中枢神经系统活动调节并释放激素,从而调节垂体激素的分泌。TH对垂体的反馈抑制作用与促甲状腺激素释放激素(TRH)的刺激作用       ___  __、相互影响,共同维持机体TSH含量的稳定。TH能进入垂体TSH分泌细胞内发挥作用,表明该细胞能通过               接受信息。
