Detailed explanation-1: -White matter is composed of bundles of myelinated nerve cell processes or axons. The axons connect various grey matter areas of the brain to each other and carry nerve impulses in-between neurons.
Detailed explanation-2: -The white matter of the spinal cord is composed of bundles of myelinated axons.
Detailed explanation-3: -White matter refers to areas of the central nervous system (CNS) that are mainly made up of myelinated axons, also called tracts.
Detailed explanation-4: -The white matter of your brain and spinal cord is composed of bundles of axons. These axons are coated with myelin, a mixture of proteins and lipids, that helps conduct nerve signals and protect the axons.
Detailed explanation-5: -Myelin is formed in the central nervous system (CNS; brain, spinal cord and optic nerve) by glial cells called oligodendrocytes and in the peripheral nervous system (PNS) by glial cells called Schwann cells. In the CNS, axons carry electrical signals from one nerve cell body to another.
