what is the difference between gray and white matter？
The central nervous system of the brain is made up of two kinds of tissue: grey matter and white matter. The grey matter contains the cell bodies, dendrites and the axon terminals, where all synapses are. The white matter is made up of axons, which connect different parts of grey matter to each other.2016年4月7日
In this way,What is the difference gray and white matter?
White matter is the whitish nerve tissue of the central nervous system that is mainly composed of myelinated nerve fibers (or axons). The central nervous system is the brain and spinal cord. And gray matter is grayish nerve tissue of the central nervous system mainly composed of nerve cell bodies and dendrites.
Furthermore,What is the difference between grey matter and white matter quizlet?
What is the difference between gray matter and white matter. Gray matter does not contain mylein sheath over the axon. White matter has a myelin sheath covering. Nodes of Ranvier are small gaps between the myelin sheath.
Long,What is the function of grey and white matter?
What is the function of gray matter and white matter? Gray matter largely functions to receive information and regulate outgoing information, as it contains the cell bodies of neurons. White matter, which is largely composed of axons, serves to transmit signals to other regions of the brain, spinal cord, and body.

What is the difference between the white and grey matter and how it's out different in the brain and spinal cord?
White matter is buried deep in the brain, while gray matter is mostly found on the brain's surface, or cortex. The spinal cord, which transmits nerve impulses to and from the rest of the body, has the opposite arrangement: gray matter at its core with insulating white matter on the outside.
What are the differences between grey matter and white matter in terms of composition and location in the CNS organs?
Grey and white matter In the brain, grey matter is mainly found in the outer layers, while in the spinal cord it forms the core 'butterfly' shape. White matter refers to the areas of the CNS which host the majority of axons, the long cords that extend from neurons.
Long thought to be passive tissue, white matter affects learning and brain functions, modulating the distribution of action potentials, acting as a relay and coordinating communication between different brain regions.
In the cerebrum and cerebellum, white matter is predominantly found in deeper areas – with gray matter coating the white matter - see figure 1. Other gray matter structures, like the basal ganglia, are embedded within this white matter core. The brain's fluid-filled ventricles are also found within the white matter.
Grey matter (or gray matter) makes up the outermost layer of the brain and is pinkish grey in tone, hence the name grey matter. It gets its grey tone from the high concentration of neuronal cell bodies in contains. Grey matter also contains unmyelinated axons.
 The grey matter throughout the central nervous system allows enables individuals to control movement, memory, and emotions. Different areas of the brain are responsible for various functions, and grey matter plays a significant role in all aspects of human life.
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.
It turns out that the human brain is very fragile. It has a consistency somewhat like jello: soft and squishy. Without preservation and chemical hardening you couldn't pick a brain up.
