Hormones play a part almost in every important function, including growth. There are several glands in the body that produce hormones, and the pituitary gland is considered the main control gland. It isn’t only to control other glands but it also produces one of the most beneficial hormones; Human Growth Hormone. The pituitary gland is located in the brain near the hypothalamus. It produces hormones in response to a complex set of chemical messages from the hypothalamus. Human Growth Hormone (HGH) operates on many tissues all over the body. It stimulates the growth of bones and cartilage for children and adolescents.
