Question

White matter is found in all of the following locations EXCEPT the ________. a) cerebral cortex b) corpus callosum c) corticospinal tracts d) outer portion of the spinal cord.

Answer 1

cerebral cortex

Step-by-step explanation:

• The tissue through which the messages are relayed between different areas of the grey matter is termed the white matter.
• The nerve fibers present in the white matter are surrounded by myelin due to which they appear white and hence, the name.
• White matter is present in deeper parts of the brain and on the superficial parts of the spinal cord in the central nervous system.
• White matter under normal conditions is absent from the cerebral cortex.
