Being one of the largest and most complex organs of the human body, the brain is made up of over 10 billion nerves which communicate in trillions of connections which are known as synapses. The brain is divided into many different regions which specialise in the different functionalities of the brain. There are many different functional sections which are known as lobes. These include the frontal lobe, the temporal lobe, the parietal lobe, the occipital lobe, the cerebellum and the brain stem.   The brain is housed inside the skull which provides frontal, lateral and dorsal protection. The skull consists of 22 bones – 14 of which are the facial bones and the remaining 8 constitute the cranial bones. The brain is actually contained within the cranium and is surrounded by Cerebrospinal fluid, a clear colourless body fluid that surrounds the brain and spinal cord. This liquid fills up any of the hollow spaces on the surface of the brain and acts as a buffer, cushioning mechanical shoc...

        The brain is structurally one of the most complex parts of the human body and is the seat of intelligence, body movements, interpreter of senses and controller of behaviour. It is the hardware of our souls and controls our thoughts, emotions, memory, sensation of touch, motor skills, vision, breathing, hunger, temperature and every process which regulates our body.    Weighing approximately 3 pounds in an average adult, the brain is mainly 60% fat and the remaining 40% is a combination of water, proteins, carbohydrates and salts. It is not a muscle at all but consists of blood vessels and nerves which comprise neurons and glial cells.     The brain consists mainly of grey and white matter which are two entirely different regions of the central nervous system (CNS). The grey matter consists of the darker, outer portion of the brain while the white matter consists of the lighter, inner section which is underneath. For the spinal cord, t...
