production of hormones and the regulation of them as well. These hormones act as chemical messengers within the body. Through several differing mechanisms‚ they are able to trigger very specific responses in target cells or organs. This is what enables the endocrine system to guide growth‚ development‚ reproduction‚ and behavior‚ among many others as well. The hormones produced from the endocrine system come from a wide range of different places. Among those responsible for hormone production

endocrine and exocrine glands‚ the location of the endocrine glands‚ and the hormones they secrete (objectives 1 and 6). It explains the nature of hormones‚ the substances that function as hormones‚ how hormones affect target tissues‚ how the secretion of hormones is controlled by a negative feedback system and the nervous system‚ the general function of each hormone‚ and the result of too little or too much of each hormone (objectives 2-5‚ 7‚ and 8). In addition‚ the text distinguishes between physical

To attain a better idea of Graves’ disease‚ attention has to be given to how the thyroid works.The thyroid is a butterfly shaped gland under the laryngeal prominence or adam’s apple‚ that is responsible for secreting thyroid hormones thyroxine (T4) and triiodothyronine (T3) that increase the body’s metabolic rate. The thyroid is regulated by the hypothalamus gland in the brain that makes thyrotropin-releasing hormones that then stimulate the

vertebrate endocrine system can be best explained as an internal body system collecting multiple organs and glands that produce and regulate hormone secretion into the bloodstream in order to control the many functions of the body. The endocrine system functions alongside the nervous and exocrine system to control and maintain growth‚ metabolism and sexual development. Hormone substances which are synthesized and secreted from cells involved within the endocrine system‚ known as endocrine gland cells‚ act

Thyroid Cancer Thyroid cancer is a cancerous tumor or growth located within the thyroid gland.Thyroid cancer is the most common endocrine cancer. Thyroid cancer is one of the few cancers that has increased in incidence rates over recent years. It occurs in all age groups from children through seniors. The American Cancer Society estimates that there will be about 62‚450 new cases of thyroid cancer in the U.S. in an average year. Of these new cases‚ about 47‚230 will occur in women and about
