激素调控促进动物生长发育的研究

The Research of the Hormonal Regulation Promote Animal Growth and Development

激素对机体的代谢、生长、发育、繁殖、性别、性欲和性活动等起重要的调节作用。动物机体通过各种内分泌腺分泌的激素,间接调节动物机体的活动。内分泌腺分泌的激素直接进入血液、随着血液循环到达身体各个部分,在一定的器官或组织中发生作用,从而协调动物机体新陈代谢、生长、发育、生殖及其它生理机能,使这些机能得到兴奋或抑制,使它们的活动加快或减慢。生长激素可以促进蛋白质的合成与骨的生长,甲状腺激素促进新陈代谢和生长发育,可以提高神经系统的兴奋。胰岛分泌的激素可以控制糖类代谢,调节血糖含量。性激素促进生殖器官的生长发育,维持第二性征。

Hormones play an important regulatory role on the body＇s metabolism, growth, development, reproduction, gender, sexuality and sexual activities. Animal＇s body through a variety of endocrine hormone secretion, indirectly regulates the activities of animal body. Endocrine glands secrete hormones directly into the blood, as blood circulation to reach all parts of the body, certain organs or tissues play a role, in order to coordinate animal body metabolism, growth, development, reproduction and other physiological functions, these functions are excited or inhibition, so that they speed up or slow down activities. Growth hormone can stimulate protein synthesis and bone growth, metabolism and thyroid hormone to promote growth and development, can increase the excitement of the nervous system. Pancreatic secretion of hormones to control carbohydrate metabolism, regulate blood sugar levels. Sex hormones to promote growth and development of reproductive organs, to maintain secondary sexual characteristics.
