Sympathetic preganglionic fibers join the ventral root of each spinal nerve from segments T1 to L2. This is part of the sympathetic chain, which runs along the spine and is responsible for the fight or flight response. The other options are not correct as parasympathetic fibers do not join the dorsal root, and postganglionic fibers do not join the ventral root.
