教科书里的观点不是都对的,因为每本教科书比当前的发展要落后5～6年。例如有示意图标明下丘脑有两个中枢,一个是周期中枢,另一个是否定中枢,这是没有证据的;有两个释放因子,一个释放卵泡刺激素,一个释放黄体生成素,但实际上只有一个释放因子黄体生成素。卵泡刺激素本身也对下丘脑无调节作用。雌激素及孕酮对下丘脑有一反馈作用,但二个激素主要作用在垂体。有动物实验证明这一 The views in the textbooks are not correct, for every textbook lags behind the current 5 to 6 years. For example, a schematic diagram shows that the hypothalamus has two centers, one is the central cycle, the other is the central negation, there is no evidence; there are two release factors, one to release follicle stimulating hormone, one to release luteinizing hormone, but in fact only A release factor luteinizing hormone. Follicle stimulating hormone itself also has no effect on the hypothalamus. Estrogen and progesterone have a feedback effect on the hypothalamus, but two hormones mainly in the pituitary. Animal experiments prove this
