Question

Why is grey matter and white matter contained in human nervous system named so?

Answer 1

White matter is made up of axon tracts. Theses tracts transmit neurons, or electric signals, to to the brain cells to communicate. The axons are wrapped in myelin, which insulates the axons and allows to send them signals quickly. The type of fat in myelin looks white, and thus white matter. Gray matter is mostly what you call glial cells. These cells are not surrounded by white myelin and thus take the grayish color.

Answer 2

Human Nervous System

Explanation:

1. White matter is comprised of axon tracts. Postulations tracts transmit neurons, or electric signs, to the synapses to impart.
2. Dim issue is for the most part what you call glial cells. These cells are not encompassed by white myelin and consequently take the grayish shading.  
3. White issue alludes to territories of the focal sensory system (CNS) that are fundamentally comprised of myelinated axons, likewise called tracts .
4. Cerebral-and spinal white issue don't contain dendrites, neural cell bodies, or shorter axons,  which messages go between various regions of dim issue inside the focal sensory system.  
5. Grey matter  (or dim issue) is a significant part of the focal sensory system, comprising of neuronal cell bodies, neuropil (dendrites and unmyelinated axons), glial cells (astrocytes and oligodendrocytes), neurotransmitters, and vessels.
6. Dark issue is recognized from white issue in that it contains various . In living tissue, dark issue really has a light dim.
