Differentiate medullated neurons from non-medullated neurons. Where are they found in the nervous system?

● Medullated neurons are present in the neurons of central nervous systems and a somatic nervous system where neurons are of larger length, present in the white matter of the brain.

● Nonmedullated neurons are present in the neurons of an autonomic nervous system where neurons are of smaller length, present in the grey matter of the brain.

● In general, neurons which are long are medullated and which are short are non- medullated.
