Bundles of sensory axons whose cell bodies are present in the dorsal root ganglion are called dorsal nerve roots. These sensory axons extend into the posterior horn of the grey matter, where they often form synapses with other neurons, some of which are called interneurons. The fasciculi of the spinal cord which carry impulses to the brain is the ascending tract. The descending tracts carry motor impulses from the brain to the spinal nerves at the different levels of the spinal cord. Hence, option 1 is the correct answer.
