Recommended: Notes on thyroid gland

The thyroid gland is a gland in the endocrine system. It helps to make and store hormones that help regulate one’s heart rate, blood pressure, body temperature, and the rate at which food is converted into energy. The thyroid hormones help every cell to function appropriately in the body. They help to regulate growth and the rate of metabolism in the body (Thompson, 2007). Without thyroid hormones we would not be able to function properly nor would children be able to physically mature and develop. The thyroid gland is located in the lower part of the neck, (in the male below the Adam’s apple), and wraps around the trachea. Its shape looks like a butterfly’s two wings (lobes) attached by a middle part called the isthmus. It usually weighs less than one ounce. The color of it is a brownish-red tone and it contains many blood vessels. Nerves are important for voice quality so that is able to pass through the thyroid.

They help to generate heart rate, blood pressure, body temperature, and the rate in which food is converted into energy. The 2 main thyroid hormones are T3 (triiodothyronine) and T4 (thyroxin). The amount of thyroid hormones secreted is controlled by another hormone, called thyroid stimulating hormone (TSH), which is released from the pituitary gland in your head ("How Your Thyroid Works"). Thyroid hormones act throughout the body, influencing metabolism, growth and development, and body temperature. During infancy and childhood, adequate thyroid hormone is crucial for brain development (Tree, 2013). The thyroid gland also makes the hormone calcitonin, which is involved in calcium metabolism and stimulating bone cells to add calcium to bone ("How Your Thyroid Works")

    First I will be discussing about the thyroid gland, so the thyroid gland is a gland in the neck that secretes hormones. These hormones regulate growth and development, and metabolism. The main hormone secreted is Thyroxine. So when a person like Margie is diagnosed with hypothyroidism it means the thyroid gland does not secrete enough hormones. As many females get over the age of 50, they are more at risk of developing hypothyroidism. The symptoms

    The location of the pituitary gland is in the sella turcica of the sphenoid bone and attaches to the hypothalamus(Marieb & Hoehn 441). The Hypothalamus is included in the function of the pituitary gland as it sends chemical stimulus to it(Marieb & Hoehn 442).Part of the pituitary is called the “ master endocrine gland” due to the fact that is produces many hormones that affect the whole body(Shannon 175).This part of the pituitary gland is called the anterior pituitary(Marieb & Hoehn 601). There are six hormones that the anterior pituitary secretes normally. These Hormones are growth hormones,thyroid stimulating hormones,adrenocorticotropic hormones,luteinizing hormones,follicle stimulating hormones and prolactin hormones( Shannon 175).The Hormone prolactin is one that in normal function stimulates the act of lactation for new mothers to feed their baby(Shannon 175).

    The thyroid gland is located in the anterior, middle portion of the neck. Many of the bodies’ hormones come from the thyroid. According to Porth 2011, “the thyroid hormone increases the metabolism and protein synthesis in nearly all of the tissues of the body.” (p. 784). When these hormones are not regulated, a thyroid disorder develops such as hypothyroidism and hyperthyroidism.

    Thyroid and metabolism hormones play a large role in the daily lives of all living species. Thyroid hormones regulate the metabolism and the metabolism is responsible for maintaining a specific range for the biochemical reactions that occur in the body (Martini 2014). The most important hormone for metabolic maintenance is thyroxine (T4). This hormone also plays a large role in body heat regulation. It is produced by the pituitary gland and secreted by the thyroid gland. The thyroid releasing hormone (TRH) must trigger the thyroid stimulating hormones (TSH) to release thyroid hormones to the thyroid gland. These hormones are under control of the hypothalamus, or main neural control center. Propylthiouracil (PTU) is a medication used to treat

  • Dessicated Thyroid versus Synthetic Therapies in the Treatment of Hypothyroidism

    1270 Words  | 3 Pages

    Hypothyroidism is an endocrine disorder that effects the lives of many people. In hypothyroidism, the thyroid gland does not produce enough thyroid hormone, causing an array of symptoms such as fatigue, weight gain, depression, swelling of limbs, lack of focus and many more. The current standard of treatment of hypothyroidism is hormone replacement therapy with a synthetic form of thyroxine (T4) called Levothyroxine or T4 Monotherapy. The whole idea behind T4 Monotherapy is that the Levothyroxine (which is a synthetic version of the natural thyroid hormone thyroxine) will mimic what occurs naturally in the body, and be deiodinated in the peripheral tissues to become the more biologically active thyroid hormone triiodothyronine (T3) and thus, alleviating the patients symptoms. Unfortunately, this however, is not always the case. For some patients, even though they are in the therapeutic range using T4 monotherapy, their bodies aren’t properly converting the synthetic T4 to active T3. Because of this, coupled with the invention of the internet, patients are turning to search engines in hopes to find an answer that will alleviate their symptoms, which has led to a resurgence in the use of desiccated thyroid products. Desiccated thyroid is derived from porcine thyroid glands, and contain both T4 and T3 thyroid hormones. Some alternative medical practioners are claiming there is more benefit in this natural product vs synthetic, but perhaps we need to take a closer look into the alternative treatment options of hypothyroidism- such as desiccated products, and why natural might not always be better.

    The endocrine system is very dynamic and has ties to most, if not all of the other major systems of the body. It is responsible for production of hormones and the regulation of them as well. These hormones act as chemical messengers within the body. Through several differing mechanisms, they are able to trigger very specific responses in target cells or organs. This is what enables the endocrine system to guide growth, development, reproduction, and behavior, among many others as well.

    In healthy an individual, the thyroid gland produces thyroid hormones T3 and T4 through a series of steps. Iodide is carry into the thyroid follicular cell from the blood stream by symporters. The iodide is transported into the cell against it concentration gradient, using Na+ concentration gradient as an energy source. The iodide in the follicular cell is activated through oxidation by thyroperoxidase (TPO). The active iodide is passively transported into the colloid through an iodide channel on the luminal side of the follicular cell down its concentration gradient. Thyroglobulin (Tg) another precursor of thyroid hormone enters the colloid via exocytosis from the Golgi complex of the follicular cell. The Thyroglobulin (Tg) binds to iodide with the help of thyroperoxidase forming monoiodotyrosine (MIT). If another iodide is added to the tyrosine reside of Tg, di-iodotyrosine is formed (DIT...

    The thyroid is one of the most essential glands in the body. It is located in the endocrine system, and sits right in the neck just above where the collar bones meet. The thyroid gland functions to produce hormones that control how every cell in the body utilizes energy, also known as a process called metabolism. When a person's thyroid abnormally produces an excessive amount of thyroid hormones, this is a condition referred to as hyperthyroidism. The causes of hyperthyroidism are known to include: eating too much food with iodine, graves disease, inflammation due to viral infections, tumors of the testes and ovaries, taking a large amount of thyroid hormone, receiving medical imaging tests consisting of contrast dye iodine, and growth of thyroid or pituitary gland (Board "Hyperthyroidism"). With an overactive thyroid, the body tends to speed up its functions. Symptoms vary from, fast heartbeats, rapid weight loss, abnormal sweating, nervousness, and mood changes. Hyperthyroidism is normally diagnosed through a series of lab tests. If not properly taken care of, condition may worsen leading to bone and heart problems in the long run. As far as treatment is concerned, options may vary from person to person depending on age and the level of activity of the thyroid. Treatments include antithyroid medicines, radioactive iodine ablation, and the last resort, surgery. Though all treatment plans work, radioactive iodine ablation is a permanent and more reliable remedy for an overactive thyroid. Radioactive iodine ablation is in fact the most commonly used cure for people with hyperthyroidism problems in the US today. “The treatment has been around since 1942 and has been extensively used since the 1950's” ("Radioactive Iodine Treatment o...

  • The Causes of Hyperthyroidism

    1437 Words  | 3 Pages

    The thyroid gland is found in the front of the neck and produces two main hormones. The hormones are called thuroxine (T4) and Triiodothyronine (T3). Together these hormones regulate the body’s metabolism by increasing energy use in cells, regulate growth and development, help to maintain body temperature and aid in oxygen consumption. These two hormones are regulated by hormones produced by the hypothalamus and pituitary gland. The hypothalamus senses changes in body’s metabolic rate and releases a hormone known as thyropin-releasing hormone (TRH). This hormone then flows through connecting vessels to the pituitary gland which signals it to release another hormone. This hormone is known as thyroid-stimulating hormone (TSH). TSH then makes its way to the bloodstream until it reaches the thyroid where it is then signaled to activate T3 and T4 production [1]. This mechanism is controlled by a negative feedback loop meaning that when there is a sufficient amount of thyroid hormones in the blood stream, this will signal back to stop production of thyroid stimulating hormones. Complications occur when the thyroid hormones keep increasing even though there is already a sufficient amount of T3 and T4 in the blood stream. This process of over expression of thryroid hormones is known as hyperthyroidism. Hyperthyroidism is a general term that includes any disease that has a consequence of an overabundance of thyroid hormones. Hyperthyroidism is a general term but there are many variant diseases that are in the hyperthyroidism category. These diseases include diffuse toxic goiter, Basedow’s disease, thyrotoxicosis, Parry’s and Graves’ disease.

    The thyroid gland is part of the endocrine system, and it is controlled by the pituitary which is known as the “master gland” of the endocrine system. The pituitary controls the thyroid by producing Thyroid Stimulating Hormone (TSH) which stimulates the production of thyroid hormones. . The thyroid gland secretes two main hormones: Thyroxine (T4) and Tri-Iodothyronine (T3). These hormones increase metabolic rate, heat production, oxygen consumption, appetite, growth hormone secretion, alertness and quicker reflexes. The thyroid gland is located in the anterior portion of the neck, beneath the Adam’s apple. It is divided in two lobes on either side of the windpipe: right lobe and left lobe. These lobes create what looks like a butterfly shape. The gland is essential to the contribution of maintaining the homeostasis of the body. It plays a role in monitoring the body’s expenditure of energy and running the body’s metabolism.
