GENERAL HISTOLOGY

Detailed explanation-1: -White matter in the spinal cord is sometimes called superficial tissue because it is located in the outer regions of the brain and spinal cord. Gray matter is situated closer to the center of the central nervous system.

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: -The most superficial layer of the meninges is the dura mater. While it has two layers in the cranial segment, the spinal dura mater only has the deep meningeal layer.

Detailed explanation-4: -Grey matter is classed as either superficial or deep. The superficial grey matter, also called brain cortex, is on the outside of the brain. The deep grey matter is made up of neurons from which originate deep nerve fibres.
