NEET PG DENTAL EXAM

Detailed explanation-1: -Besides this group of neuronal cells, the axons of grey matter are not heavily myelinated, unlike white matter, which contains a high concentration of myelin.[4] The grey matter contains the majority of neuron somas, making it appear tan with circulation but grey when prepared for examination outside of the body.

Detailed explanation-2: -White matter is found in the deeper tissues of the brain (subcortical). It contains nerve fibers (axons), which are extensions of nerve cells (neurons). Many of these nerve fibers are surrounded by a type of sheath or covering called myelin. Myelin gives the white matter its color.

Detailed explanation-3: -The white matter is composed of bundles of myelinated axons (few cell bodies) that connect various grey matter regions. Myelin is a thin layer, around the axons of white matter neurons and provides the white coloration.

Detailed explanation-4: -Grey matter refers to unmyelinated neurons and other cells of the central nervous system. It is present in the brain, brainstem and cerebellum, and present throughout the spinal cord.
