Quizplus · Accepted Answer

The posterior (dorsal) root of a spinal nerve contains the neurosomas of only sensory neurons, which enter the spinal cord through this route. The posterior ramus carries both sensory and motor neurons, while the anterior ramus contains the neurosomas of both sensory and motor neurons and gives rise to the major nerve plexuses of the body. The anterior (ventral) root contains the neurosomas of only motor neurons. The meningeal branch goes to the meninges, the protective coverings of the spinal cord.
