So did anyone else catch the inacurate reference to the "L7" vertebrae in last weeks episode? It was a good laugh considering no such vertebrae exists.
Actually, there is such a thing. It's an abbreviated expression for saying the lumbar vertebrae and it's location in the spine. L= lumber, 7= seventh vertebrae down in the lumbar section of the spine.
Yes I am aware there are only 5 in the Lumbar, but often people count the sacral as part of the lumbar on accident.
