Questions to Ponder…… Hormones and Regulation of Metabolism 1. Patrick was diagnosed with Diabetes mellitus on his 8th birthday. His 65-year old aunt was just diagnosed with Diabetes also. Patrick is having a hard time understanding why he needs injections‚ while his aunt controls her blood sugar with diet and oral medication. Why is his aunt’s treatment different from his? Patrick’s diagnosis is different than his aunt’s because he has Diabetes Mellitus type 1. This is when the body no longer

Hypothyroidism Hypothyroidism is a condition where the thyroid does not produce enough of the hormones that are required to maintain metabolism (Harvard School of Medicine‚ 2007). Introduction Hypothyroidism is not a disease itself‚ but is a condition that a disease state causes (Buckley & Schub‚ 2008). Many of the causes of hypothyroidism are related to autoimmune conditions‚ where the body attacks itself‚ rendering the thyroid useless (Raisbeck‚ 2009). In fact‚ this is the most common cause

Human Anatomy and Physiology 2 Growth Hormone and Thyroid hormones Growth hormone is produced and secreted by the anterior pituitary gland. This hormone was once believed to be of importance only during periods of active growth‚ but it is now recognized that adults produce nearly as much GH as children (Adams and Koch‚ 2009).GH stimulates the liver to produce sommatropins that then targets a variety of cells. Although its major targets are bone and skeletal muscle‚ GH stimulates many types of

How Hormones Effect the Endocrine System Introduction: The endocrine system primarily relies on the negative feedback mechanism. The endocrine system influences metabolic activities by sending out chemical messengers through the blood called hormones. Once released into the blood these hormones are transported throughout the body. The effects of these hormones are wide spread and vary from reproduction‚ growth and development‚ immunities‚ maintaining electrolyte levels‚ water and nutrient balance

Increased thyroid hormone levels in the blood result in A) further stimulus to produce thyroid hormone. B) decreased release of thyroid-stimulating hormone from the anterior pituitary. C) increased secretion of thyrotropin-releasing hormone from the hypothalamus. D) inhibition of parathyroid hormone release from the parathyroid glands. 2. Growth hormone is secreted into the bloodstream by the A) anterior pituitary. B) posterior pituitary. C) hypothalamus. D) thymus. 3. A patient has syndrome

Premium Hypothyroidism Thyroid Thyroid hormone
Thyroid hormones are essential for the body to function normally. To achieve this purpose‚ the thyroid hormones must be present in the body in the correct amount -- not too little and not too much. Hyperthyroidism is the medical term applied to an over-active thyroid gland with consequent excess secretion of thyroid hormones (T3 and T4)‚ causing the body to “speed up.” Hyperthyroidism with an enlarged thyroid gland is more popularly known as toxic goiter. What are the causes of hyperthyroidism
Premium Hyperthyroidism Thyroid
Thyroid The Thyroid or Thyroid gland is one of the largest endocrine glands in the body. The endocrine system is the system that secretes hormones and regulates the body. The thyroid is located in the lower front part of the neck‚ near the trachea and below the larynx. It comprises of two lobes connected together by the band of tissue called the isthmus. The thyroid weighs about 18-60 grams and is very light and is larger in men than women but it is bigger in women when pregnant. It looks like

Metabolism “Metabolism is the set of chemical reactions that happen in living organisms to maintain life. These processes allow organisms to grow and reproduce‚ maintain their structures‚ and respond to their environments” (Metabolism). Metabolism breaks down the food that we eat‚ transforming it into energy for our bodies. Metabolism is broken down into two categories Anabolism and Catabolism‚ which help aid in the chemical reaction process. Specific proteins in the body control the chemical

Activity Four ( Check Nutrition Unit 21) Define metabolism and describe the two forms; Anabolism and Catabolism and give examples of each? Metabolism: Every time food is swallowed‚ the body works hard to process the nutrients that have been consumed. Long after the food is digested‚ the nutrients the body has now eaten become the building blocks and the fuel of the body to keep it going. The body gets the energy it needs from food‚ and this is called metabolism. Metabolism is a collection of chemical
