Yes, you are right
Answer:
Gray matter is the region of the central nervous system comprising primarily neuronal cell bodies or soma, dendrites and unmyelinated axons.
White matter mainly consist of myelinated axons.
Explanation:
The central nervous system can be divided in several ways for easy identification namely; the left and right hemisphere, the frontal, temporal, parietal and occipital lobes.
Also, separating the brain's gray and white matter is a way of identifying the system.
The Gray matter consist of neuronal cell bodies, dendrites and unmyelinated axons.
Others include; glial cells, capillary blood vessels, neurophils.
The white matter consists mainly myelinated axons which are long relays extending from the soma and are white in colour due to the high lipid fat content of the myelin proteins that sheathes them.
Others include oligodendrocytes which are glial cells that produce myelin; astrocytes.
Answer: It is true that nervous tissue that contains predominately neuron cells bodies, dendrites, and unmyleinated axons is known as gray matter, whereas nervous tissue that consists mainly of myelinated axons is known as white matter.
Explanation: If brain and spinal cord are sectioned, two major areas of brain or spinal cord tissue can be divided on the basis of their color in fixed unstained tissue. These are the grey and white matter.
In living tissue, grey matter is actually pink due to blood in the capillaries passing through them. Grey matter consists of the neurone cell body (perikaryum), global cells, axon and dendrites.
White matter consists of axon with their myelin sheath and glial cells. No neurone perikarya are found.
