Growth hormone, also known as somatotropin, is a peptide hormone produced by the pituitary gland in the brain. It plays a crucial role in stimulating and regulating growth, development, and metabolism in humans and other animals.
In terms of growth, growth hormone is responsible for promoting cell division and differentiation, which leads to the elongation and maturation of bones and tissues during childhood and adolescence. It stimulates the production of insulin-like growth factor 1 (IGF-1) in the liver and other tissues, which further contributes to the growth and development of bones, muscles, and other organs.
Aside from its growth-promoting effects, growth hormone also plays a significant role in metabolism regulation. It helps regulate fat metabolism by promoting the breakdown of stored fat and increasing the use of fatty acids for energy. Additionally, growth hormone enhances protein synthesis and promotes the growth and repair of tissues and organs.
Growth hormone production follows a pulsatile pattern, with higher levels secreted during deep sleep and exercise. It is primarily controlled by the hypothalamus, which produces growth hormone-releasing hormone (GHRH) to stimulate the pituitary gland, and somatostatin, which inhibits the release of growth hormone. The secretion of growth hormone is influenced by various factors, including age, sex, nutritional status, stress levels, and sex hormones.
The therapeutic use of growth hormone includes the treatment of growth disorders in children and adults, such as growth hormone deficiency and Turner syndrome. Additionally, growth hormone has been used illicitly in sports and bodybuilding due to its anabolic and performance-enhancing effects, although its misuse is associated with several health risks.
The word "growth hormone" is composed of two main components:
1. Growth: The term "growth" derives from the Old English word "growan", which means "to grow, increase in size". It has Indo-European roots and is related to the Old Norse word "groa", as well as the German word "grünen" and Dutch word "groeien". Its ultimate origin is uncertain, but it likely originated from the Proto-Germanic word "gro-", which means "to grow, enlarge".
2. Hormone: The term "hormone" comes from the Greek word "hormon", which means "that which sets in motion" or "excites". It is derived from the verb "horman", which means "to set in motion" or "excite". The term was first used in a biological context by the English physiologist Ernest Starling in 1905.
