The Human Spine

Rarely do we think of the human spine until it gives us trouble, but the spine is an exceptionally well-designed, tough and flexible structure that does its job very well. It is important to understand the basic layout of the spine before trying to understand and put a name to "my aching back."

The spine is designed to support the structure of the body and house the spinal cord. The spinal cord's job is to contain the nerves that are responsible for carrying messages to and from the brain to all parts of the body.

The spine is designed to support your whole body, so you don't sink into a pile of mush. But at the same time, it is flexible enough to allow you to bend, twist and lean. It is made up of blocks called vertebra; you can find these by looking at your back in a mirror; the bony protrusions you see are the vertebra.

The vertebra is equipped with natural shock absorbers, called discs. The discs separate each vertebra, and keep the bones from (uncomfortably) grinding together. When you hear someone say they "slipped a disc" or had a disc degenerate, you can compare it in your mind to having the rubber sole of your shoe being displaced or getting too flattened out for too much wear; leaving your bare feet less protected when you run on pavement. Ouch.

The spine is able to move, flex and bend because of structures called facet joints. Think of facet joints like the links of a bicycle chain that move in a fluid motion. They are the key to the spine being able to move and function. If something goes wrong with any of these joints, the result could by pain and discomfort.

The spine has to work harder if the back and abdominal muscles are weak, if there is injury, pregnancy or weight changes, all of which can be the cause of spinal pain.

    I'm also a RB fan (easlcipely the Louis strips) and he's doing a stunning job with C-d-S this week. It's fun to see other cartoonists views of your characters and I totally support Alice in her Nap Rebellion (Day Care Spring?). http://uayceo.com [url=http://fripwhgntw.com]fripwhgntw[/url] [link=http://aozzttb.com]aozzttb[/link]

    Oh, back to part of the original post: Wet quasars. I wonder if that increases the chance of panspermia?In a star forming nebula, you've got a variety of &qmqs;eco-systeut&ouot;, from deep space up to the edge of a forming star, from icy-dust grains through to planetesimals, all the elements of a hundred solar-systems mixing together. It always struck me as a much better place for life to form than a few tidal pools on a single planet.(hoequers: Faux-class prostitutes.)

    Keep in mind, though, that even Frodo thought briefly about just letting Gollum get killed. "Only one true shot, and Frodo would be rid of the miserable voice for evo&urq.et; He does overcome that feeling, but he's not immune to it. Such a tangled mess! http://sfdrsphadm.com [url=http://uewiqc.com]uewiqc[/url] [link=http://drcqsjzkv.com]drcqsjzkv[/link]
