Do the white and gray matter of the brain live up to their name? Definitely, yes. The white matter is so colored die to the abundance of myelin that covers the neurons. After all, the main task of this part of the brain is the transmission of nerve impulses, which myelin speeds up. The gray matter, on the other hand, has a slightly different color, gray-brown. But such subtle shades of anatomy are of no importance.👐🏻 This color is due to the presence of blood capillaries and cell bodies of neurons in the substance. The function of gray matter is much more extensive than white matter - it exercises control over almost all the processes of the body.
