Understanding how the Lower Back Functions | Anatomy of the Lumbar Spine | Colorado Spine Expert


good day i’m doctor donald corenman and we’re going to discuss the anatomy
of the lumbar spine so this is the lumbar spine this is the
front here if i was a skeleton that’s what you would be staring at this is the back of the spine here these
are the spinous processes little bumps you see on people when they bend forward the lumbar spine is essentially a series
of building blocks call vertebra that sit on this triangular bone
the sacrum which is part of your pelvis this is
the base bone of your spine in the front the vertebra are separated by the discs the discs are the shock absorbers of the
spine they absorb impact and they allow motion we turn the spine around in the back of the spine we have these
paired joints called facets the facets guide the motion of the
spine forward and backward and side to side they also avoid
rotation in the lower portion they also act as door stops which we will explain in a
little bit in the center of the spine here this is the tunnel where the spinal cord
and the nerves live the nerves then come out through these
holes in each level to run down your legs and to make the muscles work we look at the back of the spine we have
these protruding processes this is called the spinous process and this
is called the transverse process they are essentially lever arms muscles attached
to them and makes it just a little easier to move the spine

    Just looking at the Lumbar Spine I can picture how it was formed over millions of years of evolution. Every part evolved for into its current form to better do the task at hand for the size of the human mammal. I wonder what the Lumbar Spine will look like in a million more years considering how we keep growing more obese as a species.
