内分泌腺主要集中在上半身,其中两个最主要的腺体位于大脑,名字叫丘脑下部和垂体。丘脑下部可说是人体内分泌的“总司令部”,所有腺体的分泌水平均由它调节,而垂体则是它的副手,随时候命输出信息往特定腺体,改变其分泌速度。说得更具体一点,它俩俨如乐团指挥和他手上的指挥棒,职责是谱出和谐的“激素协奏曲”。男女老幼体内都有这个乐团。其中性腺分泌是造成男女有别的主因,不过,男性激素并非男性独有,女性激素亦然。男性之所以具有雄赳赳的作风和粗壮的肌肉线条,主要得力于睾丸制造的雄激素,但他们体内亦有少量雌激素的存在,两相平衡,就成为一个货真价实的男子汉。但若雌激素过量,须眉也会添上女人味。相
Endocrine glands mainly in the upper body, two of the most important glands in the brain, the name is the hypothalamus and the pituitary gland. The hypothalamus can be said that the human body’s endocrine “headquarters”, all the secretion of the gland is regulated by it, while the pituitary is its deputy, ready to output information to a specific gland, changing its secretion rate. To put it more specifically, both of them are like the orchestra conductor and the baton in his hand. His job is to create a harmonious “hormone concerto.” Both men and women have this orchestra in the body. Among them, gonadal secretion is the main cause of the difference between men and women. However, the male hormone is not unique to men and the female hormone is the same. The reason why men have a masculine style and stout muscle lines, mainly due to testicular androgen production, but they also have a small amount of estrogen in the body, the two balance, to become a genuine man. However, if estrogen is overdone, the man will add femininity. phase
