Question

Brief account of structure of cerebrum

Answer 1

The cerebrum is made up of the two cerebral hemispheres and their cortices, (the outer layers of grey matter), and the underlying regions of white matter. Its subcortical structures include the hippocampus, basal ganglia and olfactory bulb.

Answer 2

Hi friend_______,

★ It is the u portion forming nearly two - third of the brain.

★ The cerebrum is longitudinally divided into two halves as right and left cerebral hemispheres by a deep cleft called median cleft.

★ Two cerebral hemispheres are interconnected by thick band of nerve fibres called corpus callosum.

★ The outer portion of each cerebral hemisphere is formed of grey matter and is called cerebral cortex.

★ The inner or deeper part is formed of white matter and is called cerebral medulla.

★ The cortex is extremely folded forming elevations called gyri with depressions between them termed as sulci that increase its surface area.

★ Each cerebral hemisphere is divisible into a frontal lobe, a parietal lobe, a temporal lobe and an occipital lobe.

★ These lobes are also known as cerebral lobes and are associated with specific functions.

★ Any damage in specific lobe in turn affects its function.

Thank you...
