Question

explain structure of cerebrum??

Answer 1

The cerebrum is a large part of the braincontaining the cerebral cortex (of the two cerebral hemispheres), as well as several subcortical structures, including the hippocampus, basal ganglia, and olfactory bulb. In the human brain, the cerebrum is the uppermost region of the central nervous system. The prosencephalon is the embryonicstructure from which the cerebrum develops prenatally. In mammals, the dorsaltelencephalon, or pallium, develops into the cerebral cortex, and the ventral telencephalon, or subpallium, becomes the basal ganglia. The cerebrum is also divided into approximately symmetric left and right cerebral hemispheres.

Answer 2

Hi friend_______,

★ It is the largest 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.
