The spinal ganglia or dorsal root ganglia contain the cell bodies of sensory neurons entering the cord at that region. nerve-a group of fibers (axons) outside the CNS. The spinal nerves contain the fibers of the sensory and motor neurons.A nerve does not contain cell bodies.They are located in the ganglion (sensory) or in the gray matter (motor). tract-a group of fibers inside the CNS. The spinal tracts carry information up or down the spinal cord, to or from the brain.n the spinal cord the synapses between sensory and motor and interneurons occurs in the gray matter. The cell bodies of the interneurons and motor neurons also are found in the gray matter. white matter-an area of myelinated fiber tracts. Myelination in the CNS differs from that in nerves.
The San Andreas fault's nick name is SAF. The San Andreas Fault is the most famous fault in the world. Its notoriety comes partly from the disastrous 1906 San Francisco earthquake, but rather more importantly because it passes through California, a highly-populated state that is frequently in the news. And with many research institutions dedicated to studying such an accessible fault, the SAF has become a household name.
California has numerous active faults throughout the state which are known to produce large earthquakes. The most active of these is the San Jacinto Fault Zone in Southern California, which has produced large events on a regular basis throughout recent history.
