Pituitary gland

Homeostasis is the action of maintaining a healthy internal environment. One example of homeostasis that we did in class is when we walked in place, causing our heart rate and breathing rate to increase while exercising to maintain a constant supply of oxygen. Another example from our reading is that sweating helps to maintain homeostasis by removing excess salt and opening pores to cool you down. It is important for organisms to maintain homeostasis because it assists the cells in the body to…

affects the Thyroid gland. Normally, the immune system protects the body from infection by identifying and destroying bacteria, viruses, and other potentially harmful foreign substances…but in autoimmune diseases, the immune system attacks the body’s own cells and organs. Graves’Dissease is the most common cause of hyperthyroidism in the United States. Hyperthyroidism is a disorder that occurs when the thyroid gland makes more thyroid hormone than the body needs. Thyroid gland makes to…

Adrenocorticotropic hormone (ACTH) is naturally synthesized by the anterior pituitary gland and its release is stimulated by the corticotrophin-releasing hormone (CRH) which stimulates the release of corticosteroids (e.g. cortisol) from the adrenal glands. ACTH plays a major role as response to any biological stress in the hypothalamic-pituitary-adrenal axis…

sodium was elevated at 150 mEq/L, and potassium was low at 3.0 mEq/L. An MRI revealed a pituitary tumor. He was diagnosed with Cushing’s Syndrome. Cushing’s Syndrome is serious condition where there is an excess amount of the hormones secreted by the adrenal cortex including glucocorticoids, mineralocorticoids, and gonadocorticoids circulating in the blood (Timby, 2014). This imbalance can be caused by pituitary tumor secreting too much adrenocorticotrophic hormone (ACTH). When there is an…

Thyroid Storm The hypothalamus, the anterior pituitary gland, and the thyroid gland all work together to regulate the thyroid hormones which in turn have a significant role in the regulation of the body’s metabolism and calcium balance (Pullen & Embrey, 2013, p. 14). When these components fail to maintain the appropriate balance of the thyroid hormones, the result can be either a hyperactive thyroid or a hypoactive thyroid. As a nurse, it is important to be able to identify patients who may be…

This reduction is caused by several types of atrophy in the brain: cortical, hippocampal, and pituitary gland (Costanza, et al., 2011). Cortical atrophy is the atrophy of the posterior cerebral cortex. This causes disruptions in visual processing. Hippocampal atrophy causes memory loss and disorientation. Atrophy of the pituitary gland, also called hypopituitarism, is when the pituitary gland does not produce adequate amounts of hormones. Without adequate amounts of hormones, the body’s normal…

Hypothyroidism is a condition where the thyroid gland does not produce much of the thyroid hormone that helps keep the normal function of the body. Hypothyroidism is also referred to as underactive thyroid gland. Normally, a person afflicted with hypothyroidism is associated with slow metabolism since the thyroid hormone is typically used to run the metabolism of the body. There are different home remedies for hypothyroidism which will benefit those people suffering from it due to its natural…

CRH. The CRH is produced in the hypothalamus and other brain regions, and is essential in uniting the immune and stress responses of the body. Once the CRH is released into the pituitary gland, it causes the pituitary to release adrenocorticotropin hormone, ACTH into the bloodstream thereby stimulating the adrenal glands to produce cortisol, which is a stress…

implant, a vaginal ring, an IUD, and a patch. The reason behind the effectiveness of hormonal methods is because the contraceptive either contains estrogen and progestin. Synthetic estrogen prevents the pituitary gland from hormones to prevent ovulation. Synthetic progestin prevents the pituitary gland from producing a hormone to prevent egg release, makes the uterus lining unable to hold a fertilized egg, and thickens the mucus in the cervic.()Each contraceptive has one or the other, few have…

is sent through the blood. Firstly, the cell inside the pituitary gland sends hormones into the blood stream over a long distance and once it gets reaches to a cell with the right receptor, the hormones will attach themselves to the receptor of that cell and go inside the cell and trigger a response. For example, the anterior pituitary lobe will release adrenocorticotropic hormone (ACTH) to stimulate cortisol production in the adrenal glands when you’re stressed. (Sargis, 2018). Pick a…
