Understanding How The Back Works-marie digby

Health You might not realize how .plex the human back really is. We take it for granted: we lay down on it, bend with it, and use it for leverage. We don’t appreciate it, that is, until something happens and we realize just how much we depended on it to help us get around! Here’s a look at the structure of the back to help you discover the way in which it works and the thing that can go wrong. The human back structure is made up of lots of little rounded bones that are stacked on top of one another that are called vertebrae. This system of bones, collectively referred to as the spinal column, has spaces in the center which allow for the passage of the spinal cord. This cord traverses your body from your tailbone on up to the bottom of the brain. The nerves that run down the spinal cord branch out between the vertebrae to convey nerve signals to all parts of the body. Your spinal column contains five sections, or general areas, according to which part of the body the nerves control: the cervical (head and neck), thoracic (chest), lumbar (lower back) and sacral (pelvis and legs). Your back has a natural curve to it which lets you move fluidly rather than with difficulty. Between each of your vertebra is a spongy, rounded structure called a "disc" that helps pad your spine and move so fluidly. While soft in the middle to ac.modate your spinal cord, their surface layer is tougher so that they can resist damage from the bony vertebrae on either side. The bony wings of the vertebrae create gaps between them that enable nerve fibers to pass through on their way to various areas of the body. The nerves branch out into the skin, tendons, ligaments, muscles and organs. At lightning speed, impulses are passed from organs to nerves to the brain, and then back to the nerves and the organ. For example, the amount of time it requires for you to put your hand on a hot stove and then pull your hand away, screaming in pain, is extremely brief. All these structures .bine to make up what we call "the back". But when you’re undergoing back pain, you wouldn’t think so. There is a .plexity to the machinations of the back that cause lots of us to suffer from aches and pains that seem like a mystery. Remember that your back provides the support system and nerve pathways to your entire body; this should help you fully .prehend just how important it is to take good care of your back.
