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: 378 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: 1543 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 levels; BMR above 1800). 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
3. State how hypothyroidism affects each of the following and describe the mechanism by which this change occurs.

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 concentration of dissolved substances is less in the extracellular fluid than in the cytoplasm. Hypotonic Solution Concentration of dissolved substances (solute) Concentration of water (solvent) What happens to an animal cells? Inside the cell Greater Less Outside the cell Less Greater Membrane

Cerebral palsy people usually very stiff and unusual relaxed and ‘’floppy ‘’ limbs which may also held in an unusual or awkward position
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
The structure that furnishes the axis for the rotation of the head from side to side is 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.
Gastroesophageal Reflux Disease or GERD, also known as Acid Reflux, is a chronic disease that happens when stomach acid flows back into your esophagus, causing irritation and discomfort. Gerd is a disease that deals with your stomach, esophagus and lower esophageal sphincter (LES). The acid that is consumed from different contents like food and liquids can escape through the LES, which is the gateway of food and acid into the stomach. The main responsibility of the LES is to keep the acid and food in your stomach, however when your LES is weak, this can cause acid to flow upward back into your esophagus and cause GERD (PDR, 2016).

Enclosed please find my application for Anatomy Instructor at Jacobs School of Medicine and Anatomical Science. I feel confident that I would be an ideal addition to the teaching faculty at the Department of Pathology and Anatomical Sciences, as you will observe that my experiences, researches and future plans are highly compatible with a number of your current faculty members. Moreover, I am presently enrolled in masters in Anatomical Science program, which further polished my teaching skills by incorporating a thesis project, graduate course-work, a teaching practicum, anatomical specimen preparation and dissection techniques. My colleagues and I are presented with a number of far-ranging opportunities from learning how to use an electron
My hand was sprinting across the page with charcoal in palm, and the finish line of my sketch was in sight. The image of a model’s face was quickly appearing, and the proportions of her eyes-to-nose and ear-to-mouth were just right. Proportions of the human face were something I learned in art class, whereas the details in her eyes were something I learned in anatomy class.
