Myelinated neurons are called as grey matter and non-myelinated neurons are called as white matter.

The correct option is B

False

The part of the brain and the spinal cord, where myelinated neurons are present in abundance is called white matter and the part where the cell body and non-myelinated neurons are present is called grey matter. Grey matter consists of the cell body of neurons and the synapses and white matter consists of the axons which interconnect different parts of grey matter.
