What are two types of matter that exist in the brain?
Two types of matter in the brain are gray matter, which contains cell bodies and synapses, and white matter, which contains myelinated axons connecting different parts of the brain. Gray matter is mostly found in the cerebral cortex, while white matter is found deeper in the brain.
Where is the gray white matter junction in brain?
The gray-white matter junction in the brain is where the gray matter (composed mainly of neuron cell bodies) transitions into white matter (composed mainly of myelinated nerve fibers). This junction is found throughout the brain, reflecting the boundary between the outer cortex and the inner white matter tracts.
Where is white and grey matter located?
White matter is mainly located in the inner part of the brain, while grey matter is found on the outer layer of the brain. White matter consists of axons that connect different parts of the brain, while grey matter contains cell bodies, dendrites, and synapses involved in information processing.
What cells are in the brain?
There are two tissues that makes up the brain and the spinal cord. These are called the grey matter and the white matter. Grey matter is what covers about a half an inch of the brain. White matter is what makes up everything else of the brain.
What is gray matter white matter how does the arrangement of gray and white matter differ in the cerebral hemispheres?
Gray matter consists of cell bodies and unmyelinated axons, while white matter consists of myelinated axons. In the cerebral hemispheres, gray matter is found on the outer cortex and is involved in processing information, while white matter is found deeper in the brain and is responsible for transmitting signals between different brain regions. The arrangement in the cerebral hemispheres is such that gray matter forms the outer layer, while white matter is located underneath, connecting different parts of the brain.
Where are the grey and white matter located in the brain?
Grey matter is located on the surface of the brain, forming the cerebral cortex, while white matter is found beneath the grey matter and deep within the brain. Grey matter consists of cell bodies and synapses, while white matter is composed of myelinated nerve fibers that transmit signals between different parts of the brain.
What is the function of the arbor vitae?
it brings sensory and motor information to and from the cerebellum
Where is White matter in the brain?
Grey matter is on the surface of the brain - it is the computing side. White matter is in the cenre of the brain it is the wires that join the computers.
What does the white matter in the brain do?
No, the white matter in brain tissue is the area of brain tissue that contains the nerve fibre tracts with their covering of myelin which appears white.
What makes brain matter white?
The myelin sheaths found on axons in the brain ("myelinated axons") gives most brain tissue a white color (= "white matter"). The grey, unmyelinated sell bodies, or "soma," of these axons reside in areas of the brain commonly referred to as "grey matter." Ben
Where in the CNS and PNS is white matter found?
White matter is found in both the central nervous system (CNS) and the peripheral nervous system (PNS). In the CNS, white matter is located deep in the brain and on the outer part of the spinal cord, consisting of myelinated axons that facilitate communication between different parts of the brain. In the PNS, white matter is present in the nerves outside of the brain and spinal cord, serving to transmit signals between the CNS and the rest of the body.
Why is Canavan disease called spongy degeneration of the brain?
Canavan disease is sometimes called spongy degeneration of the brain since it is characterized by a sponginess or swelling of the brain cells and a destruction of the white matter of the brain
