  • Essay / Hormones and their effects on the human body - 770

    The hypothalamus controls both the anterior and posterior pituitary gland, causing the release of certain hormones that allow growth, nutrition of the unborn fetus and maturation of the body. If such a complex collaboration between the hypothalamus and the posterior and pituitary gland did not exist, certain dysfunctions such as pituitary dwarfism would exist. Therefore, a collaboration between such complex glands must exist in order to release certain hormones for proper development, but the path that the hormones must travel to reach their destination involves a hypothalamic-neurhypophyseal tract and a hypothalamic-pituitary portal system. The hormones released by the posterior pituitary gland involving the hypothalamic-neurhypophyseal system consist of antidiuretic hormone and oxytocin. Antidiuretic hormone affects the kidney glands by controlling water secretion and retention, which "regulates body fluid and mineral levels (The Pituitary Foundation, 2015)." While the releasing hormone oxytocin affects the uterus and breasts, allowing the uterus to contract during childbirth and milk production after the baby is born. If these two releasing hormones did not reach these target glands, complications of incontinence, pregnancy and breastfeeding would occur. For these releasing hormones to occur, these hormones would have to travel through the hypothalamic-pituitary tract. The hypothalamic-pituitary tract involves both the paraventricular nucleus which produces oxytocin and the supraoptic nucleus which produces ADH. You must first launch a stimulus that stimulates the production of these hormones. Once the stimulus stimulates the production of ADH and oxytocin in the hypothalamus, the hormones travel along the axons to middle of paper......ormone GH which stimulates all cells in the body, helping to growth and repair of the body. Without the proper release of this critical hormone, pituitary dwarfism can occur. Pituitary dwarfism is a condition in which body length stops growing because enough growth hormone is not produced. Therefore, one would have "average stature, hands and feet", but short fingers and legs, "a disproportionate head, a prominent head, a flattened bridge of the nose and flattened cheeks (Myo Clinic, 198-2015 ). » Therefore, because insufficient growth hormone is not produced, it can lead to “delayed or no sexual development during adolescence,” delay, and premature death. Most people with this condition do not grow taller than 4 feet. Pituitary dwarfism is a condition that affects GH production due to the hypothalamus not releasing enough of this hormone..
