Document Summary
Tract provides connection from the brain to the rest of the body. Ventricular ligaments go through all layers of the meninges - fixes the spinal cord in place. Individual nerves that hang down in the lumbar region. Important because it allows us to access the spinal cord without damaging the spinal pathway. We develop this because when we are born we have a specific length - when growing and elongation occurs, it causes the original lateral projections of the spinal cord to grow vertically. The leftover dense part of the spinal cord. The leftover nerve that is connected to the scrum. In the spinal tap of a child, the cauda equina isn"t as long - so they go on the lower end. The gray matter is inside and the white matter is outside. Pathways travel on the outside, cell bodies/synapses are in the center. It only becomes a spinal nerve once the roots combine into one (ventral & dorsal)
