Cerebrum vs Cerebral Cortex The nervous system is important to
control and coordinate all the actions of an organism and
transmit signals between different parts of the body. The system
is basically made up of specialized cells called neurons. The
complexity of the nervous system increases with the complexity
of the body of organisms. Most primitive animals like sponges,
flatworms have a very simple nervous system while advanced
animals like vertebrates have a highly complex nervous system
with larger brains. Brain is one of the largest and most amazing
organs in an organism that can be categorized under the central
nervous system. The human brain can be divided into three
categories, namely, forebrain, midbrain and hindbrain. Both the
cerebrum and cerebral cortex come under the forebrain. Cerebrum
is the largest and most prominent part of the human brain. It
appears to envelop the rest of the brain as it constitutes 4/5
of its weight. It is split longitudinally into two large,
prominent hemispheres; left and
