Contains the spinal cord from the brain stem to the upper lumbar spine. There is no spinal cord in the lower lumbar spine. At the L1 level, the spinal cord terminates as the conus medullaris. A bundle of nerves called the cauda equina (meaning horse's tail) branch off the conus medullaris.These nerve roots are suspended in the fluid-filled dural sac.2 Thoracic vertebra (T1-T12). 5 Lumbar vertebra (L1-L5). The sacrum and coccyx are made up of 9 fused vertebrae. Each vertebra is attached to the one above and below it by ligaments and muscles and is separated from the vertebra above and below it by an intervertebral disc.
In the September 2014 Census Bureau report on income and poverty in the U.S., the median household income in America across all jobs was $51,939. That reflects 2013 information; 2014 data will be out in September of this year. That figure was not statistically different from 2012, reflecting continually stagnant wages.
Each figure is a mean amount, so if wages seem a little high, you can probably blame disproportionally high salaries among each country's wealthiest. To put things in perspective, the U.S. has a mean monthly income of $4,240 according to the United Nations Economic Commission for Europe. Take a look at which Europeans are on a par with that.
