1、1第 3节 激素调节典型例题一下列器官内分泌腺和激素关系正确的一组是( )A.甲状腺可分泌促甲状腺激素B.胰腺可分泌胰岛素C.垂体可分泌生长激素D.卵巢可分泌生长激素【答案】C【分析】 这道题目其实并不需要死记硬背。甲状腺不能自己促进自己分泌激素,胰腺和胰岛不一样,卵巢是雌性的生殖器官分泌的是性激素。典型例题二在某些山区,能见到经过很长时间也不变态的大蝌蚪。根据这一现象判断,这个地区人们易患( )A.地方性甲状腺肿 B.地方性侏儒症C.地方性呆小症 D.地方性“甲亢”【答案】A【分析】本题充分调动了学生的分析推理能力。首先,蝌蚪长期不能变态成青蛙,说明缺乏甲状腺激素。激素不能合成的原因最可能是

2、水和土壤中缺乏碘。那么那里的人们饮食中也必然缺乏碘,因此会引发甲状腺代偿性增生,既“地方性甲状腺肿”。典型例题三生长激素是由下列哪项分泌产生的( )A.垂体 B.胸腺 C.胰岛 D.性腺【答案】A【分析】选项中,胸腺的功能是分泌胸腺激素,胰岛的功能是分泌胰岛素,性腺的功能是分泌性激素;垂体的功能是分泌生长激素、促甲状腺激素、促性腺激素等;因此分泌生长激素的器官是垂体。2典型例题四胰岛素分泌不足的人,尿里常含有( )A.红细胞B.白细胞C.葡萄糖D.蛋白质【答案】C【分析】胰岛素分泌不足时。学堂合成糖元和血糖分解的作用就会减弱,结果会导致血糖浓度升高超过正常值,一部分血糖就会随尿液排出体外,形成糖尿,即糖尿病。因此胰岛素分泌不足的人,尿液里会含有较多的葡萄糖。尿液里出现血细胞和蛋白质是肾小球病变引起的。
