Solution

Lateral view of the cerebrum:-

Structure of the cerebrum:

  • It is the largest portion of the brain.
  • It is divided into two cerebral hemispheres connected to each other by the corpus callosum.
  • Each cerebral hemisphere is divided into four lobes - frontal lobe, parietal lobe, occipital lobe, and temporal lobe.
  • The walls have an outer cortex and an inner medulla.
  • The cortex contains cell bodies of the neuron and is greyish in colour; hence, it is called grey matter.
  • The grey matter has many folds (i.e. gyri) and grooves (i.e. sulci). They increase the surface area to accommodate more nerve cells.
  • A higher number of convolutions lead to greater intelligence.
  • The medulla consists of axons of nerve fibers and is called white matter.
