5/27/2014 ENDOCRINE DISRUPTORS AND HOW THEY AFFECT EVERYTHING “Our Stolen Future” by Theo Colborn is about the health and environmental threats created by man-made chemical contaminants that interfere with hormones in humans and wildlife. In this paper i’ll explain what is an endocrine system‚ what are endocrine disruptors‚ and how endocrine disruptors affect humans. The endocrine system includes all of the glands of the body and the hormones produced by those glands. The glands are controlled directly

The Nervous System and Aging Sensory changes can influence the way we see‚ hear‚ taste‚ smell‚ and respond to touch and pain. This in turn affects how we experience the world and react to things. A significant sensory change can rob us of many simple pleasures and complicate the tasks of daily living. It may mean reduced mobility‚ increased dependence on others‚ inaccurate perception of the environment‚ reduced ability to communicate and socialize‚ or loss of self-esteem. Sensory changes vary

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

Central Nervous System: The central nervous system consists of the brain and spinal cord. The brain controls bodily functions. The cerebrum is the largest part of the brain in humans. The cerebrum is the last place that information travels through in the brain. The spinal cord is the part of the body that communicates between the brain and the nerves that connect to the spinal cord. The spinal cord is commonly known as a pathway from the brain to the body. Peripheral Nervous System: The peripheral
