Meronyms (parts of "neuron"):
axon; axone (long nerve fiber that conducts away from the cell body of the neuron)

afferent neuron; sensory neuron (a neuron conducting impulses inwards to the brain or spinal cord)

nervous system; systema nervosum (the sensory and control apparatus consisting of a network of nerve cells)
Derivation:
neural; neuronal; neuronic (of or relating to neurons)
