Adrenal gland In mammals‚ the adrenal glands (also known as suprarenal glands) are the triangular-shaped endocrine glands that sit on top of the kidneys. They are chiefly responsible for releasing hormones in conjunction with stress through the synthesis of corticosteroids and catecholamines‚ including cortisol and adrenaline (epinephrine)‚ respectively. Anatomy and function Anatomically‚ the adrenal glands are located in the retroperitoneum situated atop the kidneys‚ one on each side. They are

HGH: The Game Changer The use of human growth hormone (HGH) in professional leagues is constantly discussed. If their athletes should be allowed to use it. HGH is currently an illegal drug in all professional leagues‚ they believe it helps with the performance of an athlete and gives them an advantage. If these organizations allow their athletes to use HGH would enhance the game and make the game better in so many ways. If the only realize that HGH has little to no anabolic affects on the athletes
Premium Growth hormone Hypothalamus
is known to be caused by a tumour of the pituitary gland‚ a gland located at the base of the brain from where it releases hormones that regulate several functions of the body – one being growth. Pituitary tumours can cause tissues to grow abnormally resulting in certain changes in facial appearance‚ enlarged hands and feet‚ headache and sweating – eyesight too can be affected; this condition is called acromegaly. If someone has excess growth hormone‚ they become excessively tall and become an acromegalic

Thyroid hormones are essential for the body to function normally. To achieve this purpose‚ the thyroid hormones must be present in the body in the correct amount -- not too little and not too much. Hyperthyroidism is the medical term applied to an over-active thyroid gland with consequent excess secretion of thyroid hormones (T3 and T4)‚ causing the body to “speed up.” Hyperthyroidism with an enlarged thyroid gland is more popularly known as toxic goiter. What are the causes of hyperthyroidism

The Human Growth Hormone and Its Effects on Our Bodies as We Age In this paper‚ I will explain what the human growth hormone is; its effects on our bodies as we age. Also‚ show the benefits received by following a prescribed treatment plant from a qualified physician. The results are amazing‚ as you will see; this has prompted more research into the benefits of hormone replacement therapy as we age.

Understanding the Functions of Proteins and DNA Ingrid Waldron‚ Biology Department‚ University of Pennsylvania‚ 2012 These key concepts and activities are suggested as part of an introductory unit on biological molecules (or as an introduction to a unit on molecular biology). The overarching goal is to help students understand that proteins and DNA are not just abstract concepts in biology textbooks but rather crucial components of our bodies that affect familiar functions and characteristics

endocrine system is a system of glands‚ each of which secretes a type of hormone into the bloodstream to regulate the body. It derives from the Greek words endo meaning inside‚ within‚ and crinis for secrete. The endocrine system is an information signal system like the nervous system. Hormones are substances (chemical mediators) released from endocrine tissue into the bloodstream that attach to target tissue and allow communication among cells. Hormones regulate many functions of an organism‚ including

thyroid gland is an important organ of the endocrine system and located in front of the neck below the larynx consisting of two lobes on each side of the windpipe. It regulates the physical and chemical processes that occur at the cellular level. It regulates the manner and rate at which the tissues utilize food and natural chemicals for the production of energy and to expend that energy into body heat and muscular energy. The thyroid gland produces hormones from the thyroid tissue cells called triiodothyronine

How Primary Structure Determines Protein Function Proteins are everywhere. As enzymes‚ they catalyse chemical reactions. There are many different types of proteins: carrier and channel proteins which transport substances‚ receptor proteins which are recognition site for antibodies and hormones‚ structural proteins which support cells and tissues‚ and hormones which transmit information. Proteins are big molecules with large molecular masses that are made up of many amino acids; they’re‚ essentially
