Reading Bradford’s article entertained me continuously, involving profound facts regarding the human body about the thyroid function. With the ability to secrete hormones thyroxine(T4), calcitonin, and (T3) into the blood stream. Explaining the fact that hormones manage the speed at which organs and cells develop nutrients into vigor, including the time oxygen cells expenditure. “In this way, the thyroid gland is the body’s master metabolic control center,” said Cindy, Samet, existing as a chemistry professor, serving a presence at Dickinson College in Carlisle, Pennsylvania. The thyroid can regulate the nerve function development and brain, functions having to do with the hair, skin, heart, and …show more content…
“Women are particularly at risk for a thyroid issue,”Hershman said. “One in eight women will develop a thyroid disorder during the course of their lives- that’s five to eight times the rate in men.”
Graves’ disease was discovered by Irish doctor Graves’.J.G in (1835). Graves’ disease is a autoimmune disorder, with the immune system attacking the thyroid gland which inappropriately makes it over active. A symptom of a thyroid condition is a protuberance on the neck, located in the center called a goiter. An increase in the heart rate is a symptom as well, according to the National Library of Medicine (NLM).
Hypothyroidism
Is the opposite of graves’ disease, and occurs when not enough hormones are produced by the thyroid gland. Causing the human body’s function to decrease or possibly stop it for good, Hershman said. Another disease that can affect the thyroid is cancer, the journal of the American Medical Association (JAMA) was published in 2017, discovered in the 1975’s. In 2013 the amount of thyroid cancer patients diagnosed has tripartite. With the now known knowledge of a swelling or lump on a thyroid gland is labeled a nodule. Some nodules can increase the development of too much hormone, which might be carcinogenic. Stated and researched by the Endocrine Society, hormone@endoctrine.org. In such medical cases cancerous, the thyroid
Alice Neel’s painting Suzanne Moss was created in 1962 using oil paint on canvas. As the title suggests, the painting depicts a woman’s portrait. Now resigning in the Chazen Museum in Madison, WI, this portrait of a woman lunging is notable for the emotional intensity it provokes as well as her expressionistic use of brush strokes and color. The scene is set by a woman, presumably Suzanne Moss, dressed in dull back and blues lounging across a seat, staring off to the side, avoiding eye contact with the viewer. The unique style and technique of portraiture captures the woman’s piercing gaze and alludes to the interior emotions of the subject. In Suzanne Moss, Alice Neel uses desultory brush strokes combined with contrast of warm and cool shadows
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
Hypothyroidism develops when the thyroid gland does not produce enough of certain hormones. (“Hypothyroidism”, n.d.). Hypothyroidism can be broken down even further. The two types of hypothyroidism are congenital hypothyroidism or acquired hypothyroidism. According to Porth 2011, “Congenital hypothyroidism develops prenatally and is present at birth. Acquired hypothyroidism develops later in life because of primary disease of the thyroid gland or secondary to disorders of hypothalamic or pituitary origin.” (p. 786). Some common symptoms include increased sensitivity to cold, dry skin, fatigue, constipation, drowsiness, hypothermia and muscle weakness (“Hypothyroidism”, n.d.).
Graves’ disease is an autoimmune disease that was discovered by Robert Graves in 1835. Graves’ disease is an autoimmune disease in which the body's immune system attacks the thyroid gland and causes hyperthyroidism. Graves’ disease occurs when the antibodies like thyroid-stimulating immunoglobulin and thyrotropin receptor antibodies (TRAbs) attack the thyroid gland as if it were a foreign object or a virus of some sort. This disease is the most common type of hyperthyroidism. Attacking the thyroid gland in such a manner makes it excessively overproduce the hormone thyroxine which controls the body’s metabolic rate. Heightened activity of the thyroid can increase the body’s metabolism by 60% to 100%. (Weeks 34-35).
Today in America thyroid disease is becoming a much larger issue and the worse part of this problem is that many people are not yet diagnosed. This is due to the lack of education and awareness about thyroid disease. There are many different types of diseases but the one that I am passionate about is hypothyroidism. Hypothyroidism, or underactive thyroid is when the thyroid is no longer able to produce triiodothyronine, also known as T3 and thyroxine, also referred to as T4. Some of the symptoms include unexpected weight gain, tiredness, depression, or slow movements and thoughts. Most of the time many people notice the way that their bodies act on what they are feeling to their physicians. Many Americans struggle with this disease that
The reasons why are unclear, but there is a sharp distinction between male and female thyroid cancer rates - females tend to develop the cancer more by nearly three times as often (“What Are the Risk Factors for Thyroid...
Tumors and growths of all kinds can form in the thyroid gland. Thyroid tumors are usually benign, which is not cancerous; but doesn’t mean that they can’t be malignant, which are cancerous and spread quickly into nearby tissues and other glandular areas of the body. Thyroid cancer can happen to anyone at any age. According to the Essentials of Human Diseases and Conditions textbook; “The four main types of thyroid cancer are papillary (small nipple-like projections), follicular (saclike balls of cells), medullary (affecting the interior portion of the gland, and anaplastic (loss of differentiations of cells).” (Schell Frazier & Drzymkowski Wist, 2013)
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 balance of the thyroid hormone is complicated and involves the participation of different parts of the body (Kaplustin, 2010).
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...
Abstract Anne Hutchinson was derided for rhetorical purposes. She was accused of breaking the 5th amendment in the Puritan’s colony which she was banished from the colony. During trial, she said that God spoke to her. John Winthrop didn’t like her theological conclusions, and that’s why he banished her. Religion professor Stephen Prathero says “Anne Hutchinson is the future of religious tolerance.
This is because the tissue swells around the eyes and suffer from hyperthyroidism, muscular weakness, and rapid pulse and develop a reddish, painless skin rash. People who show signs and symptoms usually are either mild or severe. It all depends on the activity level of the thyroid. The disease affects the immune system itself and no other places. Symptoms usually develop over a 3-month period. The carrier usually is not aware that they have Graves’ disease. They usually find out when the symptoms are severe. The common signs are weight loss, tremors, feeling of being hot, and palpitations. (www.ncbi.nlm.nih.org). The less common sign that can occur as well. They are over activity of the intestines, which leads to frequent bowl movements. Sometimes the breakdown of protein in muscles can lead to extreme weakness, which causes trouble breathing and limited endurance. (The Thyroid Book). The thought of having Graves’ disease can be disturbing. Mood swings and thinking impairment can be difficult to handle. Crying spells, depression and feeling down are common. The patient’s personality can be different and will change. This could make work difficult and hard to keep. Generally, a person with Graves’ disease will have a thyroid that is enlarged but will not have any pain from it. This is called a goiter and can be seen in the neck most of the time. Sometime you cannot see the goiter but by feeling and examining the neck, it can be detected.
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.
Among these disorders are hypothyroidism and hyperthyroidism. Hypothyroidism is a disorder in which one is diagnosed for having and underactive thyroid. The probability for women over the age of sixty to develop an underactive thyroid is higher than those of other individuals. If left untreated it can potentially lead to obesity, joint pain, heart disease, and other health complications. On the contrary, hyperthyroidism is a disorder in which a person is diagnosed for having an overactive thyroid. This can cause nervousness and anxiety, hyperactivity, unexplained weight loss, and swelling of the thyroid gland which causes a noticeable lump to form on throat (known as a

This type of cancer has the ability to spread quickly and the farther that it hits, the harder it can be overcome if at all.” This form of thyroid cancer often occurs in the inherited genetic disorder multiple endocrine neoplasia” (Thyroid Cancer 2). People who have inherited multiple endocrine neoplasia will most likely have medullary thyroid cancer, but it is rarely contracted without this disorder. Next, anaplastic thyroid cancer is the most fatal of all four subtypes. This types of cancer grows quickly and metastasizes to other parts of the body rapidly. “Anaplastic thyroid cancer is more likely to develop in men over the age of 70” (Thyroid Cancer).
