The usual name for a bundle of nerve processes within the CNS is "tract" or "fasciculus"
These nerve pathways would generally be described as the peripheral nervous system.
Axons and dendrites that go to or from the same region of the body travel together in bundles, somewhat like telephone cables. A nerve is a bundle of axons and/or dendrites in the PNS. A bundle of axons and/or dendrites in the CNS is called a tract.for more info see link below
Bundles of neuron processes are called tracts in the cns and nerves in the pns
It is called a dendrite.~
the spinal nerve sends nerve impulses away from the CNS
Eletrical impulses throughout the nervous system
A neuron is an individual cell in the PNS or CNS that can be excited and conduct impulses along its axon. A nerve is a bundle of multiple neuron fibers that each are carrying their own signals. They are protected by connective tissue. Eventually the neuron fibers diverge away from the nerve to reach their destination.

Sometimes the term ganglia is used as in the sympathetic and parasympathetic ganglia of the autonomic nervous system.
In the peripheral nervous system, which is outside the central nervous system (CNS), collections of nerve cell bodies are called ganglia.
