Thyroid hormone Essays

Where is the thyroid produced and what is the target organs what is the normal function? The thyroid gland located in front of the neck below the Adams apple, produces the thyroid hormone. It targets most tissues. The function of the thyroid hormone (TRH) is to increase the metabolic rate. This leads to an increase in oxygen and heart rate, stimulates appetite increase breakdown of nutrients and promote growth. Production of the thyroid hormone is controlled by thyroid stimulating hormone (TSH) which

Meet your thyroid The thyroid gland controls how hard other parts of your body work by producing hormones (chemical messengers) that increase the energy burnt off by almost every tissue and organ.⁶ Hormones produced by the thyroid ensure that your heart pumps properly, that you can breathe and move, and that your liver and kidneys get rid of toxic waste. Thyroid hormones are essential for reproduction and to make sure your baby is healthy. Thyroid hormones help keep you looking well and attrac-

INTRODUCTION The thyroid is Greek word for “shield shaped” from the shape of the nearby tracheal cartilage. The thyroid gland was named “glandulae thyroidaeae” by Wharton in 1656.[1] The thyroid gland is the source of two fundamentally different types of hormones, produced by thyroid follicles, idothyronine hormone thyroxine (T4) and 3, 5, 3’- triidotyronine (T3). Fig 1.1:- Conversion of T4 to T3 and Reverse T3. 1.1 Regulation of thyroid hormones in human body Thyroid hormones (T3 & T4) are essential

type 1 diabetes, or much more. Graves’ disease though; is an immune system disorder that results in the overproduction of thyroid hormones, also known as hyperthyroidism. (“mayo clinic”) Several other disorders may result in hyperthyroidism, but this is a very common cause. Graves disease can affect anyone, but is more common in women that are over the age of 40. Thyroid hormones can affect a number of different body symptoms, therefore symptoms and signs of Graves’ disease can range from a variety

experiencing between the ages of 11 and 15. The pituitary gland is responsible for the secretion of Growth Hormone (GH), Thyroid Stimulating Hormone (TSH), Adrenocorticotropic Hormone (ACTH), and Luteinizing Hormone (LH) as well as other hormones. We will focus on the four hormones above because they are the cause of the symptoms Eric is experiencing. The first hormone to address is Growth Hormone or GH. Eric shows signs of GH over-secretion from the pituitary gland. This would cause his tall, skinny

Can Hypothyroidism Cause Depression? In making the effort to determine if hypothyroidism has a causal relationship to depression we find indeed there is. In terms of which came first, this is a crucial clue as to the effects of an under active thyroid gland. It involves the choice of remedy, but moreover, it calls upon the patient to do some legwork in their own process of getting well. Masking the Symptoms Will Not Do Why is that, you ask? It comes down to the nature of treatment in allopathic

Thyroid hormone is an essential hormone which requires plasma membrane transport protein to travel into the cells to help the brain function properly throughout the life. Thyroid hormone deficiency leads to hyporeflexia, lethargy, brain damage and etc. depending on onset and duration of time period. Thyroid hormones perform various different roles in life from age to age as people grow from infant to elderly. The mice were mostly used to understand the aspect of thyroid physiology and the thyroid

cell carcinoma is a rare type of thyroid cancer that has a bad prognosis (outlook). Under the microscope, Hurthle cells are cells that look bigger than the usual follicular cells of the thyroid. There are several options of treatment for this type of thyroid malignancy, but it is important that it is recognized and treated early. Part 1: What Is Hurthle Cell Carcinoma? Hurthle cell carcinoma makes up only about three percent of all cancers affecting the thyroid gland. This neck gland is butterfly-shaped

of the thyroid gland may happen because of increased TSH levels, or in response to the autoimmune process that occurs in Graves’ disease” (2015, Linda, S Williams, et al). According to the Mayo Clinic “Your thyroid is a butterfly-shaped gland located at the base of your neck just below your Adam's apple” (2014). If you can imagine how skinny your neck is, you can imagine how noticeable an enlargement would be. The thyroid gland is primarily controlled by a hormone called TSH or the thyroid-stimulating

used in the treatment of thyroid cancer and is considered one of the most successful types of cancer treatments. Iodine is stored within the thyroid gland of the body. Humans are unable to make iodine so it must be absorbed through food. Iodine is necessary for the thyroid gland to be able to produce hormones. Iodine deficiency can also be very dangerous and lead to many different health problems. There are many benefits in using Iodine-131, mainly related to the thyroid gland. It can be used to

Hyperthyroidism (overactive thyroid) is a condition in which your thyroid gland produces too much of the hormone thyroxine. Hyperthyroidism can accelerate your body's metabolism significantly, causing sudden weight loss, a rapid or irregular heartbeat, sweating, and nervousness or irritability. (http://www.thyroid.org/what-is-hyperthyroidism.) Hypothyroidism (underactive thyroid) is a condition in which your thyroid gland doesn't produce enough of certain important hormones.

INTRODUCTION Severe thyroid dysfunction may mimic almost any psychiatric symptom profile.1, 2 even before the determination of serum thyroid hormone concentrations and before suppressive and substitutive thyroid therapies became widely available, and there are reports about psychopathological syndromes associated with thyroid dysfunction such as “myxoedematous madness.”1 Mild or latent thyroid dysfunction may be associated with more or less subtle psychiatric abnormalities.3 The prevalence of

system. The systems support basic body functions, coordinate and complement each other to protect and instigate homeostasis by the aid of hormones (Harvey 2013, p. 15). The endocrine systems release these hormones and are then transported to the desired organs and cause-effect by the aid of receptors. The Thyroid and Normal Anatomy of the Thyroid The thyroid gland is one of the most important organs in the endocrine gland. It weighs between 15 and 20grams and slightly heavier in women. It is red

Thyroid disorders are abnormal functions of the thyroid gland. Hypothyroidism and hyperthyroidism are types of thyroid disorders, affecting women older than 60 years more than men with a rate of 24%.1 People who suffer from thyroid disorders experience many symptoms such as a high blood pressure, development of a goiter, and muscle aches. Undiagnosed thyroid disorders people who unknowingly have one of thyroid disorders are approximately 43%, which indicates a high number of people who may experience

hypothyroidism or we can say the early stage of hypothyroidism. Body of patients suffering from this disease mounts an immune reaction against its own thyroid gland tissues which leads to the inflammation of the gland and the

appreciate the thyroid gland, one must understand its importance in controlling metabolism, body temperature, and muscle strength. The thyroid is a butterfly shape gland that sits in front of the throat and it is part of the endocrine system. The thyroid gland produces hormones that influence every organ, tissue, and cell in your body. Such a small gland that controls so many functions in the body. The thyroid gland controls the body’s metabolism, this is how the body uses energy. Thyroid disorders can

the thyroid gland. It is the most common cause of hyperthyroidism. Thyroid’s secretion of thyroid hormones [Triiodothyronine(T3) and Thyroxine(T4)] is regulated by thyroid stimulating hormone (TSH), which is released by the pituitary gland. These hormones regulate the body’s metabolic rate, heart function, brain development, bone maintenance and etc. In Graves’ disease, the immune system creates autoantibodies that mimic the function of TSH and stimulate production of more thyroid hormones. Consequently

ABSTRACT Introduction: The aim of the study is to find the antioxidant status in hypothyroidism. Hypothyroidism otherwise known as under active thyroid. It takes place when the thyroid gland doesn’t produce enough thyroid hormone for the body need. It is the most common thyroid disorder. It occurs mostly in women and increase with age Material and Methods: 40 subjects were divided into two groups of normal healthy individual ( 20 in numbers ) as Group I and hypothyroidism patients ( 20 in numbers)

suffering from a form of thyroid disease, and sixty percent of them have no idea about their condition. Hypothyroidism accounts for up to ninety percent of thyroid imbalances. How can such as large percentage of people have a disease they are unaware of? There are a number of signs and symptoms related to hypothyroidism or under-active thyroid that can be associated with other conditions. Hypothyroidism is a condition where the thyroid gland is not producing enough thyroid hormone (T4 thyroxine and T3

Adetutu Okupe Bio 2108K Lab February 3, 2015 Data Analysis and Interpretation Objectives: In this experiment, the assumption that severely obsessed hyperparathyroidism primary patient has larger glands and higher levels of parathyroid hormone. In determining this fact, the variables collected would be used to establish if the hypothesis is true or not. Introduction: To proceed with this experiment, it is imperative to understand the operational definition which is Primary hyperparathyroidism. This
