vaxtarhormónum

Vaxtarhormónum, also known as somatotropin or growth hormone (GH), is a peptide hormone produced by the anterior pituitary gland. Its primary function is to stimulate growth and cell reproduction in humans and other vertebrates. In children, GH promotes the growth of long bones, leading to increased height. It also plays a role in muscle growth and bone density.

Beyond its role in childhood growth, vaxtarhormónum continues to be important throughout adulthood. It influences metabolism by promoting protein synthesis, fat breakdown, and glucose regulation. Vaxtarhormónum also contributes to tissue repair and regeneration, wound healing, and immune function.

The production of vaxtarhormónum is regulated by hormones from the hypothalamus, primarily growth hormone-releasing hormone (GHRH) and somatostatin. GHRH stimulates GH secretion, while somatostatin inhibits it. Sleep, exercise, and low blood glucose levels can also increase GH release.

Deficiencies in vaxtarhormónum can lead to conditions such as dwarfism in children. Conversely, excessive production, particularly during childhood, can result in gigantism. In adulthood, excess GH can cause acromegaly, a condition characterized by the enlargement of hands, feet, and facial features. Synthetic forms of vaxtarhormónum are used therapeutically to treat GH deficiency and certain other medical conditions.
