Question

With the help of a labelled diagram of lateral view of cerebrum, describe the structure .

Answer 1

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.
