Detailed explanation-1: -Gray matter in the cerebrum creates the cerebral cortex, which is responsible for our conscious perception of movement, sensation, and association between the two. White matter in the cerebrum functions to connect areas of the same or different hemispheres of the brain, as well as communicate with the spinal cord.
Detailed explanation-2: -The grey matter creates a hornlike structure throughout the inside of the spinal cord while the white matter makes up the surrounding sections of the spinal cord. The grey matter does extend to the spinal cord to make signaling more effective.
Detailed explanation-3: -White matter is made of axons connecting different parts of grey matter to each other. In the brain proper, grey matter forms the outer layer of the brain, and white matter forms the inner layer. In the spine, this is reversed: white matter forms the outer layer of the spine, and grey matter the inner layer.
Detailed explanation-4: -Grey matter has no myelin sheath, while white matter is myelinated.
Detailed explanation-5: -In the brain proper, grey matter forms the outer layer of the brain, and white matter forms the inner layer. In the spine, this is reversed: white matter forms the outer layer of the spine, and grey matter the inner layer.
