❶The outer layer of cerebral hemispheres is called cerebral cortex or neopallium.




Because of man's rapid evolution in technology and medicine, humans now know a great deal more about their own nervous system then they did even a few years ago.

This increase in knowledge is partly due to the recent advances in nuclear medicine.

Lastly, the occipital lobe is the smallest of all four cerebral lobes. This part of the brain is responsible for visual reception and processing, recognition of colors, and movement. Thus, it can be concluded that human brain is a very complex organ which is responsible for multitude functions, and an unknown number of those functions is not yet known.

There is still ongoing research on the composition and functions of brain. Each of the parts of the brain is responsible for some essential function without which the body will not be able to function normally.

This attribute makes the brain the most essential part of the human body.

They consist of an anterior club shaped olfactory bulb and posterior olfactory tract. The cavity of the olfactory lobes or rhinocoel is not well marked. The olfactory lobes are the centers of smell. The cerebral hemispheres or cerebrum is the largest part of the brain occupying about two-third of the entire brain.

It is divided into right and left cerebral hemispheres by a deep longitudinal median groove Fig. These two cerebral hemispheres are connected by a transverse sheet of nerve fibres, called corpus callosum Fig. The anterior part of corpus callosum is bent slightly downward to form genu while the posterior part is raised upward to form splenium.

The cerebral hemispheres are divided by 3 deep fissures into 4 lobes viz. The parietal lobe or the somaestic area is the centre for the perceptions of sensations like pain, touch and temperature. The occipital lobe has two areas viz. On the ventral side there is a longitudinal fissure called rhinal fissure which separates the hippocampal lobe or pyriform lobe from anterior lobe in each cerebral hemisphere.

Insula or Island of Reil is a small lobe of cerebrum, covered over by parietal frontal, and temporal lobes. It co-ordinates the action of different regions of cerebral hemispheres. The outer layer of cerebral hemispheres is called cerebral cortex or neopallium. It is formed of grey matter and contains millions of neurons. Grey matter also forms islands on the white matter. These are called cerebral nuclei. The cerebral cortex is highly convulated in order to increase its surface area.

The ridges of these convultions are called gyri and depressions between them as sulci. The cavities within the cerebral hemispheres are called lateral ventricles First and second ventricles which open to third ventricle cavity of diencephalon by a foramen of Monro Fig. The centres of reception of these are located in the sensory areas called soma esthetic area present in the parietal lobe.

It is the last part of the forebrain and is almost covered dorsally by cerebral hemispheres. On its dorsal surface it bears a pineal stalk with a rounded pineal body at its top. The dorsal vascular wall forms anterior choroid plexus. Its cavity is called diocoel or third ventricle.

On the ventral side hypothalamus forms the floor of the diocoel. It consists of number of scattered masses of the grey matter in the white matter.

The Human Brain Essay Words | 5 Pages. The human brain is a big, intricate—yet delicate, structure in the human body. It is the key structure in cognitive function. Any damage to the brain does not only “erase” memories but also may “deceive” the brain to erroneously remember a new object as being familiar (). The Brain and Meningitis - Meningitis is an inflammation of the membranes (meninges’) surrounding the brain and spinal cord. Meningitis has several causes including bacteria, chemical irritation, drug allergies and most commonly viruses.
