WHITE NEURON:
myelinated or medullated or white neuron:
when the axon is enclosed by the white fatty myelin cover, it is called myelinated or medullated or white neuron. This form the white matter of our brain.
GREY NEURON:
non-myelinated or non-medullated or grey neuron:
this neuron is not enclosed by the myelin sheath; so it appears greyish in colour. The axon is covered only by neurilemma and schwann cells. This type of neuron is found in the grey matter of cerebrum.
