Human Growth And Human Growth, And The Adverse Effects Of The Digestive 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

TSH not only stimulates the thyroid gland to churn out more hormones. If in excess, can cause overwhelming cell growth and division to result in goiter.

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

HGH, or human growth hormone, is regulated by the growth hormone-releasing hormone produced in the hypothalamus. Influenced by sleep, stress, exercise and food intake, the growth hormone-releasing hormone determines how much HGH to release into the bloodstream32.

The endocrine system is a group of glands distributed throughout the human body. This group of glands secretes substances called hormones. These hormones are dumping into the bloodstream (Shier, Butler & Lewis, 2009). The endocrine system does not have a single anatomic location. It is dispersed throughout the human body. The final purpose of this process is to control, regulate, and coordinate the functioning of the human body. Some body functions can be activated or inhibited by hormones, which are secreted in very small quantities. The hormone related diseases may be due to hyper secretion, or a hypo secretion. The hormones secreted by the endocrine glands regulate growth, development and function of many tissues, and coordinate the

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

Because of the endocrine system’s critical role in so many important biological and physiological functions, impairments in any part of the endocrine system can lead to disease or even death. For example, diabetics have deficiencies in insulin release and/or action, and people with type I diabetes will die without insulin replacement. Aldosterone is also critical for life, and adrenal diseases affecting aldosterone function can be life-threatening. Often, under- or over-secretion of hormones such as thyroid hormone results in metabolic disturbances and many physical and neurobiological changes, due to thyroid hormone’s key role in day-to-day cellular metabolism and brain function. Other hormonal dysfunctions include infertility, growth disturbances,

Normal secretion of growth hormone is regulated by the hypothalamus. Normally, growth hormone from the hypothalamus is transported to the anterior pituitary gland where it is released. GH released from the anterior pituitary binds to and activates specific cells (Roiger). Growth hormone is released in a pulsatile manner and acts on the liver, bone, cartilage, muscle, and adipose tissue to stimulate the production of insulin-like growth factor-I (IGF-I). Circulating IGF-I in the body is derived mainly from the liver and feeds back on the anterior pituitary and hypothalamus to inhibit further growth hormone secretion (Patel, Ezzat and Chik).

young. Low levels in adults results in a lower metabolic rate causing weight gain, memory problems,

The function of the thyroid gland is to manufacture and store the body’s important hormones that support the internal regulation of body temperature, blood pressure levels, and the heart beat rhythm. These hormones circulate through the bloodstream and impact the performance of every tissue and cell. The thyroid gland hormones also play a significant role in a person’s

Thyroid hormones play a major role in many tissues, protein synthesis and muscle function. The thyroid gland uses iodine from the foods you eat to make two main hormones which are Triiodothyronine (T3) and Thyroxine (T4). T3 and T4 travel in your bloodstream to reach almost every cell in the body. The hormones regulate the speed with which the cells/metabolism work. For example, T3 and T4 regulate your heart rate and how fast your intestines process food. So if T3 and T4 levels are too high, your heart rate may be faster than normal, and you may have an increased rate of metabolism. This is called hyperthyroidism. A study was carried out to measure the effects of hyperthyroidism on distal muscles of the upper limb. Hand grip strength, dexterity

The thyroid is responsible for maintaining the body’s homeostatic functions including metabolic rate, growth, and nervous system development. Normal thyroid function is regulated through the feedback control of the hypothalamus-anterior pituitary gland-thyroid axis. The hypothalamus, which maintains homeostasis, produces thyroid releasing hormone (TRH). TRH stimulates the anterior pituitary to produce thyroid stimulating hormone (TSH aka thyrotropin). TSH acts on the thyroid gland, causing it to produce the hormones, triiodothyronine (T3) and thyroxine (T4). Both T3 and T3 act in a negative feedback loop, with T3 inhibiting the hypothalamus, and T4 inhibiting the anterior pituitary gland (Ota, 2016) . Thyroid follicular endothelial cells contain thyrotropin receptors. Antibodies against thyrotropin receptors develop, stimulating receptors on these follicular endothelial cells, stimulating excess production of thyroid hormone (Bahn, 2010). [See Figures 1 and

Thyroid hormones, thyroxine (T4) and triiodothyronine (T3), are implicated in numerous process, including growth and development of muscle, bones and the central nervous system (CNS); metabolism by increasing basal metabolic rate, calorigenesis and appetite; and have cardiovascular effects due to they make the heart beats faster and harder. Deregulation of the correct function of the thyroid can lead to different pathological process such as hypothyroidism, hyperthyroidism, thyroiditis, goiters, thyroid cancer and solitary thyroid nodules. The determination of thyroid hormones, especially FT4, together with TSH is an important element in clinical routine diagnosis. It is useful when thyroid disorders are suspected and also for the monitoring of therapy.

The thyroid regulates your metabolism, your appetite, muscle function, blood pressure, heart rate, among other things. And a way that it interacts with the pituitary is a good example of a negative feedback loop, a method of communication that's common all over the body and especially in the endocrine system. Basically, the pituitary is like the thyroid's thermostat. It can read how much thyroid hormone is in your blood stream and when its levels are low, it spits out a tiny bit of thyroid stimulating hormone, or TSH, which travels to the thyroid. The thyroid, in turn, secretes thyroid hormone, which boosts our metabolism, and that increase in metabolism tells the pituitary to stop sending out TSH. So the effect of the pituitary secretion is

The pituitary gland controls your growth, puberty, metabolism, the amount of water in your body, minerals, balance, and also the body's stress.
