Growth hormone (GH) is an ancestral hormone secreted episodically from somatotroph cells in the anterior pituitary. Since the recognition of its multiple and complex effects in the early 1960s, the physiology and regulation of GH has become a major area of research interest in the field of endocrinology.
What type of hormone is growth hormone?
Growth hormone is a protein hormone of about 190 amino acids that is synthesized and secreted by cells called somatotrophs in the anterior pituitary. It is a major participant in control of several complex physiologic processes, including growth and metabolism.
Is growth hormone a paracrine hormone?
In summary, GH and PRL are not just endocrine hormones, as they have autocrine and/or paracrine roles in health and disease.
How is growth hormone classified?
Growth hormone is a peptide hormone that stimulates growth, development and regeneration. This peptide hormone is made up of 191 amino acids that form a long, single-chain polypeptide. Growth hormone is synthesized in the somatotropic cells, which are found in the anterior pituitary gland.
What is the main function of the growth hormone?
Growth hormone-releasing hormone is a hormone produced in the hypothalamus. The main role of growth hormone-releasing hormone is to stimulate the pituitary gland to produce and release growth hormone into the bloodstream. This then acts on virtually every tissue of the body to control metabolism and growth.
What does growth hormone do in adults?

Which body part growth is independent to growth hormone?
To further complicate the picture, IGF-I production in newly discovered GH target sites such as the brain, heart, and reproductive organs is largely GH-independent and is instead controlled by other factors such as gonadotropins or estradiol .
What is the effect of endocrine hormone in the growth and development?
Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body. The endocrine hormones help control mood, growth and development, the way our organs work, metabolism , and reproduction.
Which hormone is responsible for height?
Growth hormone is produced by our brain’s pituitary gland and governs our height, bone length and muscle growth.
What are growth hormones give example?
Growth hormone (GH) or somatotropin, also known as human growth hormones (hGH or HGH) in its human form, is a peptide hormone that stimulates growth, cell reproduction, and cell regeneration in humans and other animals.
