They even help in our body growth, reproduction, and even sexual characteristics.
Hormone is a chemical substance that is formed in our bodies which controls and regulates the functions of our body. Many of the hormones are secreted by special glands like thyroid hormones are secreted by thyroid glands of our body and they affect the function of that very gland. Hormones are of crucial importance because they help the organs of our body to carry out their functions properly. They even help in our body growth, reproduction, and even sexual characteristics. It also affects how our body stores and releases energy in the form of salt and sugar, which means it has a key role in our metabolism processes, growth of cells, and heart functions like heartbeat and pumping of blood.
Since we talked about how hormones can be secreted by different glands, we can also point out that there exist three major types of hormones- lipid derived hormones, amino acid derived hormones, and peptide hormones. Lipid derived hormones are derived largely from cholesterol and they are similar in structure too. Examples include testosterone and progesterone, etc. Amino acid derived hormones as the name suggests are derived from amino acids. They are small structured and include hormones secreted in the adrenal glands and thyroid gland. The peptide hormones are those hormones whose molecules are made up of proteins that is why these hormones are also called protein hormones. Examples include the hormones secreted by the pituitary gland and oxytocin etc. Image will be uploaded soon
Growth hormone is a peptide hormone that is secreted by the lobe that is anterior in the pituitary gland. Other than growth hormone it is also called human growth hormone and since this hormone is released by cells called somatotrophs present in the pituitary glands, the growth hormone is also known as somatotropic hormone. As the name suggests, its primary function is to boost the growing process of our body tissues and cells. The growth hormones increase the synthesis of protein in the body which also helps in boosting the breakdown processes of fats which, in return, provide the required energy to the body for cell formation and tissue growth. The growth hormones rarely act directly on the tissues for growth. It is mostly through the generation of insulin-like growth factors that are stimulated by growth hormones in the liver and other parts of the body that it helps in boosting growth processes.
There are many effects of growth hormone in our body. Some of them are-
When too much growth hormones are secreted, they cause the tissues to grow abnormally. In children, this disease is called gigantism, and in adults, it is called acromegaly. It is diagnosed by X-rays and blood tests and generally caused by cancerous tumors in the pituitary glands.
Some of the important growth hormone functions are –
Growth hormones are peptide hormones that are secreted by the anterior lobes of pituitary glands. Growth hormones are of two types- one, natural and the other, synthesized. Somatotropin hormones are the naturally occurring growth hormones in humans and animals. Somatropin hormones are synthesized growth hormones that are produced by recombinant DNA technologies. Hypersecretion of growth hormones is related to over secretion of growth hormones in a body. If too much growth hormones are released, then the growth of body issues take place abnormally leading to abnormal body organs. It is generally caused by the presence of benign tumors in the pituitary glands. It leads to an abnormal condition called gigantism in children and acromegaly in adults.
