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.
San Andreas Fault. The San Andreas Fault is the transform boundary between the North American Plate and the Pacific Plate. During the 1906 San Francisco earthquake the northern section of the San Andreas Fault slipped northward along the fault from San Juan Bautista to Cape Mendocino, a total of 296 miles (477km). transform boundary is a fault zone where two plates slide past each other horizontally. Most transform faults are found in the ocean where they offset spreading ridges creating a zigzag pattern between the plates.
