Options
- AGrey matter
- BWhite matter
- CAssociation areas
- DCerebral cortex
Correct answer
A. Grey matter
Step-by-step solution
The cerebral cortex contains motor areas, sensory areas, and large regions that are neither clearly sensory nor motor in function. These regions, called the association areas, are responsible for complex functions such as intersensory associations, memory and communication.A deep cleft divides the cerebrum longitudinally into two halves, which are called the left and right cerebral hemispheres. The cerebral cortex contains motor areas, sensory areas, and large regions that are neither clearly sensory nor motor in function. These regions, called the association areas, are responsible for complex functions such as intersensory associations, memory and communication.
The layer of cells that covers the cerebral hemisphere is referred to as the grey matter due to its greyish appearance as the neuron cell bodies are concentrated here. The corpus callosum is a tract of nerve fibres that connects the left and right cerebral hemispheres.
