It is true that the elder brother Tang's facial features are exquisite and beautiful, and with this Adam's apple, in the author's view, a stranger is like jade, a son chinese odyssey? I'm sure it's not much difference.
So someone asked a question: Why is the Adam's apple obvious for boys, but it seems that girls don't have this structure, and boys' Adam's apple is also large and small.
First of all, the formation of Adam's apple is related to androgen secreted by human body. In the process of human growth, the human body will secrete androgen or estrogen. As the name implies, boys secrete more androgens, while girls secrete more estrogens. The reason why the man's Adam's apple grows bigger and more obvious is mainly because of the development of adolescence. During this time, women's breasts will become bigger and will also usher in menarche; For men, it is obvious that the Adam's apple will become bigger, and the front end of the thyroid cartilage plate will grow rapidly, so the Adam's apple looks very prominent, and the voice will change because of the changes in the cartilage of the throat and neck, that is, boys'? Voice change period? .
It must be mentioned here that thyroid cartilage has been developing since the embryo, and the largest thyroid cartilage is the thyroid cartilage plate, and its size also affects the Adam's apple. However, because there is not much hormone secretion in women and men before puberty, it is impossible to distinguish sex through Adam's apple at a young age.
Women also secrete a small amount of male hormones in adolescence, but the amount of these hormones is not enough to provide girls with Adam's apple like boys, so women's Adam's apple is not as obvious as men's.
Some men's Adam's apple is not an obvious problem. From the foregoing, we can already know that the development of male Adam's apple is related to the amount of androgen. If the Adam's apple is not obvious, the first problem is that his androgen is less than the average person. There are two common reasons for the decrease of male androgens.
The first point is that he did too much strenuous exercise in adolescence, which led to the exhaustion of androgen in the body and his Adam's apple was not as obvious as that of ordinary boys.
Second, adolescence is too much to solve the needs by hand. In such an ignorant period, there may be many such things, on the one hand, because they pursue excitement, on the other hand, they are also curious about such things.
