This morning when I woke up, I was pondering how deeply circulation goes in the body and was pleasantly surprised to run across these images in Frank Netter's "Atlas of Human Anatomy." The photo on the right is your basic spinal cord image. It shows gray and white matter and some nerve roots and that's about it. I have to say, when I visualize the spinal cord, this is the image that has come to mind......until now!

The images on the right show the arterial and veinous blood flow that runs in and out of the spinal cord. This happens all day. 24/7. That's life giving blood bringing essential substances (groceries) into the cord and carrying the cell debris (garbage) out. That's deep....literally.....actually.......really.

I appreciate this kind of bodymap refinement. I find it helpful to have an accurate picture in my mind of what is really going on inside of me. It's comforting to know that cells can constantly change, repair and grow and to have a picture in my mind of just how deeply that goes. Just imagine that for a moment...........
