INTRODUCTION
The endocrine system is the system of glands, each of which secretes different types of hormones directly into the bloodstream to regulate the body. The endocrine system is an information signal system like the nervous system, yet its effects and mechanism are classifiably different. Hormones are substances (chemical mediators) released from endocrine tissue into the bloodstream where they travel to target tissue and generate a response. Hormones regulate various human functions, including metabolism, growth and development, tissue function, sleep, and mood. * Endocrine system includes * Hypothalamus * Pineal

    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.…

    Why Women are More Likely to Develop Thyroid Disorders

    Thyroid is a small gland found at the base of your neck, just below your Adam 's apple. The thyroid produces two main hormones called T3 and T4. These hormones travel in your blood to all parts of your body. The thyroid hormones control the rate of many activities in your body. These include how fast you burn calories and how fast your heart beats. All of these activities together are known as your body 's metabolism. A thyroid that is working right will produce the right amounts of hormones needed to keep your body’s metabolism working at a rate that is not too fast or too slow.…

    What Is My Greatest Failure

    One of my most accomplished failures was AP Government in my sophomore year of high school. AP Government was my first AP course, and it is incredibly important to me because it helped me learn and realize my future career goals. Many would say that receiving a C grade is not failing, but to me it was. I was devastated after receiving my grade, which lead me to question whether or not I was advanced enough to take the class. I was unsure of what career I wanted to pursue in the future, but I knew that doing well in school would be essential to my success. After working hard and studying immensely for the rest of the year, my grade rose every quarter and I earned a higher grade to finish the year. Ap government has always been one of my proudest accomplishments. My “failure” in AP government helped me work harder, expose myself to new environments and realize my career path.…
