The Endocrine System In The Human Body
The Endocrine System

Texas Woman’s University

Introduction The endocrine system is one of two systems in the human body that regulates all bodily functions. It is comprised of organs called endocrine glands and include the ovaries, testes, pituitary, hypothalamus, pineal, pancreas, kidneys, thyroid, parathyroid, thymus, and adrenal glands. These glands, which are spread throughout the body, are responsible for the extensive and enduring release of certain hormones into the bloodstream for delivery to target cells. Hormones are chemical messengers which have specific functions; only cells with the proper receptor proteins can receive them. Once a hormone attaches to a cell’s receptor protein, the cell responds according …show more content…
Children with this disorder will develop noticeably slower than others and have attention and anxiety problems. Although it is mostly men who are affected with this hereditary condition, women can be affected. A narrow face and large ears are physical characteristics of a person with Fragile X syndrome. By testing for mutations in the FMR1 gene, doctors can diagnose a patient with Fragile X syndrome (GHR 2015b). Laron syndrome is another inherited endocrine disorder in which a person is unable to use growth hormone. The child will appear normal at birth, but then grow very slowly and be significantly shorter than people who can process growth hormone. People with this disorder commonly have less muscle and lower blood sugar, as well as smaller genitals and protein deficiencies. They are also more at risk for become obese. Mutations in the GHR gene are responsible for Laron syndrome (GHR 2015c). The endocrine system is a relatively small yet extremely important system of the human body. Without it, humans would not survive. Daily function and long-term development depend upon hormones secreted from glands in the endocrine system. One little mutation can give a person serious problems for his or her entire …show more content…

    Endocrine System - Mayville State University

    OVERVIEW The endocrine system, like the nervous system, controls body activities to maintain a relatively constant internal environment. The methods used by these two systems are different. This chapter describes the difference between 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 and psychological stress, and describes how the endocrine system mediates the stress response (objectives 9 and 10). A knowledge of the function of the endocrine system is basic to the understanding of how metabolic processes are regulated to meet the changing needs of the body.…

    Endocrine System Essay

    The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things. The endocrine system is a very important system in the human body. There are many endocrine glands in this system, including -but not limited to- the pituitary gland, hypothalamus, pineal gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, gonads, placenta, thymus, heart and gastric and intestinal mucosa. Endocrine glands are ductless glands that secrete hormones directly into the blood stream. The basic function of the endocrine system is to maintain homeostasis. The endocrine system uses hormones to communicate/control.…

    Fragile X Syndrome, FXS, is a condition in the brain that makes difficulties in developing. Both genders can be affected but males seem to be more affected by it. On the X chromosome, a gene called FMR1 is mutated. The mutation on the FMR1 gene prevents the gene from creating protein. It can affect the way you learn or think. Processing problems, speaking, everyday things are different from an average person. Some symptoms that could occur is anxiety, hyperactive behavior or attention disorder.…

    Watson And Crick Turner Syndrome

    Also, scientists are now able to identify specific chromosomes involved in certain disorders such as Down Syndrome, Turner Syndrome, and Klinefelter Syndrome. An individual with Down Syndrome has an extra copy of chromosome 21 (“Chromosomal Abnormalities,” par. 1). Only women can have Turner Syndrome which occurs when a female has only one X chromosome. Females with this disorder may have an array of developmental and medical problems; they are also sterile (“Turner Syndrome,” par. 1). Klinefelter Syndrome, which occurs when a male has an extra X chromosome, affects cognitive and physical development (“Klinefelter Syndrome,” par. 1). In addition to these disorders, there are also sex-linked disorders like colorblindness, hemophilia, and muscular dystrophy. One must also consider recessive disorders, dominant disorders, and codominant disorders which have been identified and understood partly because of Watson and Crick’s DNA research.…

    Pattern of Inheritance - The genes associated with these conditions are located on the X chromosome, which is one of the two sex chromosomes. In males (who have only one X chromosome), one altered copy of the gene in each cell causes the condition.

    Fragile X syndrome has traditionally been considered an X-linked dominant condition with variable expressivity and possibly reduced penetrance. However, due to genetic anticipation and X-inactivation in females, the inheritance of Fragile X syndrome does not follow the usual pattern of X-linked dominant inheritance and some scholars have suggested discontinuing labeling X-linked disorders as dominant or recessive.…
