You answered: 1536.6 ml O2/kg/hr 3h. Calculate the oxygen consumption per hour for this rat using the following equation. ml O2 consumed/1 minute x 60 minutes/hour = ml O2/hour Enter the oxygen consumption per hour in the field below and then click Submit to display your results in the grid. You answered: 384 ml O2/hr 3i. Now that you have calculated the oxygen consumption per hour for this rat, you can calculate the metabolic rate per kilogram of body weight with the following equation (note that you need to convert the weight data from grams to kilograms to use this equation). Metabolic rate = (ml O2/hr)/(weight in kg) = ml O2/kg/hr Enter the metabolic rate in the field below and then click Submit to display your results in the grid. You answered: 1573.8 ml O2/kg/hr Judging from their basal metabolic rates (an indicator of thyroid function), categorize the rats as hypothyroid (low thyroid levels; BMR below 1600), euthyroid ("good," or normal, thyroid levels; BMR = 1650-1750), or hyperthryoid (high thyroid

Hypothyroidism, while a common disorder, is often misdiagnosed due to its ability to mimic other common health problems. A simple, yet specialized blood test, coupled with a complete medical history, will allow the experts at RCMC Medical Center to not only diagnose the problem in a timely manner, but also develop a treatment plan based on the results, and your personal lifestyle, with the end goal of returning you to the level of health and wellness you

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

The normal rat is You correctly answered: b. euthyroid Judging from their basal metabolic rates (an indicator of thyroid function), categorize the rats as hypothyroid (low thyroid levels; BMR below 1600), euthyroid ("good," or normal, thyroid levels; BMR = 1650-1750), or hyperthryoid (high thyroid levels; BMR above 1800). The thyroidectomized (Tx) rat is You correctly answered: a. hypothyroid Judging from their basal metabolic rates

Also on the screen are three white rats in their individual cages. These are the specimens you will use in the following experiments. One rat is normal; the second is thyroidectomized (abbreviated on the screen as Tx), meaning its thyroid has been removed; and the third is hypophysectomized (abbreviated on the screen as Hypox), meaning its pituitary gland has been removed. The pituitary gland is also known as the hypophysis, and removal of this organ is called a hypophysectomy. To the top left of the screen are three syringes with various chemicals inside: propylthiouracil, thyroid-stimulating hormone (TSH), and thyroxine. TSH and thyroxine have been previously mentioned; propylthiouracil is a drug that inhibits the production of thyroxine. You will perform four experiments on each animal to: (1) determine its baseline metabolic rate, (2) determine its metabolic rate after it has been injected with thyroxine, (3) determine its metabolic rate after it has been injected with TSH, and (4) determine its metabolic rate after it has been injected with propylthiouracil. You will be recording all of your data on Chart 1. You may also record your data on-screen by using the equipment in the lower part of the screen, called the data collection unit. This equipment records and displays data you accumulate during the experiments. Check that the data set for Normal is highlighted in the Data Sets window; you will be experimenting with the normal rat first. The Record Data button lets

A. Hypothyroidism is a disorder that occurs when the thyroid doesn’t make enough thyroid hormone for the body’s

Thyroid research came about after a paper published in 1850, written by Thomas Curling talking about two girls who had severe malformation and were placed in an idiot asylum. One of the girls, 10, could not walk or talk very well; the other, 6 months, “was plump but had a marked idiotic expression, a large face with a small

Incidentally, there are actually two compounds made in the thyroid that are called thyroid hormone. The most abundant is T4, also known as thyroxine, which is then converted to T3, or triiodothyronine. T3 is the active form that produces the effects on metabolism.

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

e. People who have had a thyroid problem before, received radiation for a thyroid problem, or had surgery on the thyroid are most likely to develop hypothyroidism.

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

Hyperthyroidism is caused by an excess of thyroxine (T4) or triiodothyronine (T3), or both. This excess is a result of a malfunction of the thyroid gland as indicated by the picture below. There are many different symptoms of hyperthyroidism, some of the most common being major weight loss despite having a insatiable appetite, anxiety, heat intolerance, fatigue, weakness, hyperactivity, irritability, apathy, depression, and sweating. In addition, many experience shortness of breath, loss of balance, nausea, vomiting, osteoporosis, and diarrhea. However, those who undergo hyperthyroidism later in life may not experience most of these symptoms at all and instead only feel constantly fatigued and considerable weight loss. Nonetheless, neurological symptoms may occur in addition to the physical manifestations. These neurological symptoms include tremor, chorea (ticks), myopathy (muscle weakness), and temporary but periodic paralysis. There are a variety of ways to treat hyperthyroidism, depending on the age of the patient, the size of their thyroid gland, and their general health. The most common treatments include beta-blockers, which do not actually cure hyperthyroidism but mask some of the symptoms such as tremors, anxiety and so on. This, however, is not advised for those with heart or lung problems. Another possible treatment for this disease is radioactive iodine, or RAI. RAI therapy is the most common treatment for hyperthyroidism

The subjects were Sprague-Dawley male rats. Their age is 150 days. The supplier is Harlan Sprague-Dawley. They are maintained on a 12:12 h light/dark cycle and are provided with ad libitum access to food.
