Growth Hormone in Psychological Processes - Research Paper ExampleExcessive production of growth endocrine gland gets caused by the growth of a benign tumor in the somatotroph cells. This condition gets referred to an adenoma. A tumor of the islets of Langerhans or the lung which produce Growth endocrine-releasing hormone can also shake off excessive production of growth hormone. The growth hormone interacts with insulin through the IGF axis. The liver secretes insulin like growth factor 1- IGF-1, in response to secretion of the growth hormone (Juul & Jens, 2000). The IGF axis interaction is vital in the inhibition of cell death and promoting cell proliferation. IGF-1 is necessary for achieving maximal growth. Gigantism can get more heterogeneous to treat than dwarfism. This is so because some forms of dwarfism get caused by insufficient production of growth hormone. These forms of dwarfism can become rectified by providing the diligent with growth hormone (Artwelle & Vislon, 200 8). Gigantism, however, results from the overproduction of growth hormone. This can become hard to correct as it is more difficult to place the excess growth hormone in the required normal range. The metabolic rates in a giant also become hyper abnormal, this contributes to a less life expectancy for giants. The hypophysis gland gets located in the brain. It is divided into the anterior and posterior lobe. The pituitary gland secretes prolactin hormone, which stimulates the production of breast milk and the control of menstrual periods (Ho, 2011). lactogenic hormone activates the mammary glands to generate milk. During pregnancy, prolactin concentrations rise causing enlargement of the mammary glands. Also produced in the pituitary gland is the hormone vasopressin. Vasopressin also gets referred to as anti-diuretic hormone. This hormone encourages water retention by the kidneys. This hormone works in the kidneys collecting ducts to stimulate reabsorption of water by the body.
