Growth Hormone

Growth hormone (GH), also known as somatotropin, is a peptide hormone that stimulates growth, cell reproduction, and regeneration in humans and other animals. It is produced by the pituitary gland, a small gland located at the base of the brain, and plays a crucial role in various physiological processes.

Functions of Growth Hormone

Promotes growth and development of bones, muscles, and tissues
Regulates metabolism by increasing the utilization of fats for energy
Enhances the synthesis of proteins and promotes tissue repair
Stimulates the growth of internal organs
Regulates the balance of water, fat, and minerals in the body
Supports the immune system functions

Regulation of Growth Hormone

Growth hormone secretion is regulated by a complex interplay of hormones and feedback mechanisms. The hypothalamus, a region of the brain, releases growth hormone-releasing hormone (GHRH) to stimulate the pituitary gland to produce and release GH. Conversely, somatostatin, another hormone produced by the hypothalamus, inhibits the release of GH. Additionally, levels of GH are influenced by factors such as stress, exercise, nutrition, and sleep.

Disorders Related to Growth Hormone

Imbalances in growth hormone levels can lead to various disorders:

Gigantism: Excessive GH production before the closure of the growth plates, leading to abnormal overgrowth of bones and tissues
Acromegaly: Excessive GH production after the closure of the growth plates, resulting in enlarged hands, feet, and facial features
Dwarfism: Insufficient GH production or resistance to its effects, leading to stunted growth
Growth Hormone Deficiency: Inadequate production of GH, resulting in poor growth in children and various metabolic disturbances

Study Guide

To understand growth hormone thoroughly, consider the following study guide:

Describe the structure and location of the pituitary gland.
Explain the functions of growth hormone in the human body.
Discuss the regulation of growth hormone secretion by the hypothalamus and pituitary gland.
Compare and contrast the disorders related to growth hormone, including gigantism, acromegaly, dwarfism, and growth hormone deficiency.
Explore the factors that influence growth hormone levels, such as stress, exercise, nutrition, and sleep.

By mastering these concepts, you will have a comprehensive understanding of growth hormone and its significance in human physiology.
