The Effect Of The Pituitary Secretion In The Endocrine System

Week 3 – LOM Assignment The thyroid is responsible for taking iodine and converting it into thyroid hormones which are released into the blood stream and transported throughout the body where they control metabolism.1 The thyroid is a vital part of the human body as every cell in the body depends on it for metabolic regulation. Too much or too little thyroid hormone secretion can result in hyperthyroidism or hypothyroidism. Hyperthyroidism is caused when the thyroid secretes too many thyroid hormones. Hyperthyroidism causes a rapid heart rate, elevated blood pressure and tremors. Other symptoms include increased nervousness, inability to concentrate, weakness, restlessness, difficulty sleeping, frequent bowel movements, weight loss and irregular

Thyrotoxicosis is a clinical condition caused by excess circulating serum thyroxine (T4), triiodothyronine (T3), or both with suppression of thyroid-stimulating hormone (TSH). A negative feedback loop involving the hypothalamus, pituitary, and thyroid gland regulates the production and release of thyroid hormones. (Fig. 1) The hypothalamus releases thyroid-releasing hormone (TRH), stimulating the pituitary gland to release TSH, in turn stimulating the thyroid gland to release T4 and T3. Enhanced production of T4 and T3

World War II was a time of great urgency and sacrifice that called upon unity for not just soldiers, but also everyday citizens. America needed a way to get this message across quickly and effectively and so they did it in the forms of posters and speeches. The World War II propaganda that was created to unite and encourage patriotism across the United States played a pivotal and vital role in the United Nation’s victory.

The thyroid is a butterfly-shaped gland. You would find it located in the lower neck, right below the Adam’s apple. The location is the same in both men and women. What the thyroid does is create and store thyroid hormone. It then releases the hormone in appropriate amounts to keep the body’s metabolism functioning at a normal level. If there is too much thyroid hormone, this is known as hyperthyroidism. In hyperthyroidism, the body’s metabolism increases. This condition can cause high blood pressure, high heart rate, nervousness, palpitations, and severe weight loss. Too little thyroid hormone, on the other hand, can cause tiredness, depression, memory loss, dry skin, brittle hair, and weight gain—among many other symptoms.

The thyroid is a small gland that rests in the lower neck. It is in charge of controlling the body’s metabolism by producing hormones (such as T3 and T4) that tell the body’s cells how much energy to use (2). The pituitary gland is in charge of monitoring the quantity of thyroid hormones in the bloodstream (2).

The case is about the same with thyroid hormones. The hypothalamus is apart of the brain that produces thyroid-releasing hormones. This hormone pairs with what is known as our pituitary gland to begin the production of a thyroid-stimulating hormone. This pairing up acts on the thyroid in order to produce thyroid hormones, which travel through our bodies.

The thyroid gland is the gland that makes and stores hormones that help regulate the heart rate, blood pressure, body temperature, and metabolism. Thyroid hormones are essential for the function of every cell in the body. They help regulate growth and the rate of chemical reactions in the body. Thyroid hormones also help children grow and develop. The thyroid gland is located in the lower part of the neck, below the Adam's apple, wrapped around the trachea. It has the shape of a butterfly with two lobes attached to one another by a middle part called the isthmus. The thyroid uses iodine, a mineral found in some foods and in iodized salt, to make its hormones. The two most important thyroid hormones are thyroxine (T4) and triiodothyronine

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

Thyroid Function Tests: The thyroid’s job is to make thyroid hormones, which are secreted into the blood and the carried to every tissue in the body. The major thyroid hormone secreted by the thyroid gland is thyroxine, also called T4 as it contains four iodine atoms. T4 is converted to T3 (triodothyronine) by removal of iodine atom. It occurs mainly in liver and in brain. The amount of T4 produced is controlled by another hormone which is made in the pituitary gland located at the base of brain, called thyroid stimulating hormone (TSH). The amount of TSH is in the blood depends on the amount of T4 that the pituitary sees. If the pituitary sees very little T4, then it produces more TSH to tell thyroid gland to produce more T4.When T4 in the bloodstream goes above a certain level, the pituitary’s production of TSH is shut off. The thyroid and pituitary act like heater and a thermostat. If it’s cold the thermostat reads the temperature and turns on the heater. Thus, the thyroid and pituitary, like heater turn on and off. T4 and T3 circulate almost entirely proteins, and when these proteins change their level in the blood, there is change in T4 and T3 levels.

Hashimoto’s Thyroiditis, also called Hashimoto’s disease is an autoimmune disease in which the body’s immune system attacks the thyroid gland. It was named for the Japanese surgeon who discovered it in 1912 The thyroid is a small butterfly shaped gland in the front of the neck. The thyroid makes hormones called T3 and T4. These hormones regulate metabolism. The thyroid is controlled by hormones of the pituitary gland, which is also called the “master gland.” It is a pea-sized gland located in the base of the brain which, among others, makes thyroid stimulating hormone, or TSH. TSH stimulates the thyroid to make thyroid hormone. With Hashimoto’s disease, the thyroid cells are damaged resulting in the inability to make enough thyroid

In the film Mulan, it displays many cultural aspects of what China was like in the Han dynasty. The film is about a girl called Mulan, who ignores her gender role as a female to secretly go in her father’s place in the army in fear of him dying and ends up saving all of China. I’ll be discussing two events that happened in this film to discuss the gender roles of women and family honour.

Edgar Allan Poe, can be considered the most prestigious literary writer there has been. Regardless of him dying so young, it’s amazing the amount of stories and poems that he was able to accomplish. The majority of these themes are related to destruction, insanity and death. The way he managed to use different styles of literature, is what sets him apart from all of the other writers, and make his name stand above everyone else. For us to be able to understand his writing, or the reason behind of his ideology, we must look and explore the past.

Thyroid hormone production is regulated by a hormone called thyroid stimulating hormone and it is made in the brain by the pituitary gland. Since it occurs in the thyroid gland, thyroid hormones affect metabolism, brain development, body temperature, skin dryness, and it speeds up many of the body’s functions. The

Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. Thyroid hormones play a vital role in regulating the bodys metabolic rate, heart and digestive function, muscle control, brain development and maintenance of bones.

Within field studies, the best way to understand the workings of the endocrine system usually involves injecting a specimen with a hormone or removing the gonads of the specimen to observe changes in hormone concentrations (Mazur, Booth, & Dabbs, 1992). However with human subjects this kind of procedure proves to be rather unethical, and therefore researchers have found that the best way to observe a particular hormone, such as testosterone, is to observe what occurs when an individual is subjected to competition (Mazur et al., 1992). It has been observed that as an individual, male or female, participates in a competitive event, their testosterone levels are subject to rise (Booth, Shelley, Mazur, Tharp, & Kittok, 1989). This notion is further supported through the observation of rising testosterone levels in those individuals who win their event. In fact it has been suggested that an individual’s testosterone level increases in order to maintain an aura of dominance, and thus the act of winning a competition increases the level of testosterone in order to maintain that dominance and level of competitiveness over the game (Booth et al., 1989). While testosterone levels increase with victory, defeat often inspires the decrease of testosterone levels as well as feelings of competitiveness (Booth et al., 1989). This phenomenon is not limited to just those individuals competing in an event; in fact it has also been observed that even those watching a particular
