Q

white vs grey matter

A

The central nervous system of the brain is made up of two kinds of tissue: grey matter and white matter. The grey matter contains the cell bodies, dendrites and the axon terminals, where all synapses are. The white matter is made up of axons, which connect different parts of grey matter to each other
