Cerebral hemisphere

The human brain, just like all the other parts of our body is unique. It gives us the power to speak, think and to solve problems. It works by using the electrical and chemical process to take in, organize, interpret, store and use information. The nervous system is divided into central nervous system (CNS) and peripheral nervous system (PNS). The CNS consists of the brain and spinal cord and they are the decision makers of the body. Sensory information gathering and action transmission occurs…

The brain is supplied with oxygen to keep it alive by a network of blood vessels. Structure of the brain The brain is made up of 4 main parts and they are: ● The cerebral cortex, ● Limbic system, ● The cerebellum ● and the brain stem The cerebral cortex The cerebral cortex is split into two cerebral hemispheres (the left and right hemispheres). Sometimes…

When the body becomes exposed to chronic exposure to alcohol the body will adapt to changes thus causing different responses to it. A person that drinks alcohol all the time will build up a tolerance to alcohol and will not get the effect as a person that drinks once and while or rarely drinks. The brain will start to develop a pathological craving for alcohol, longer the chronic drinker uses alcohol the stronger the desires become to fulfill them. If the body does not get the desired fix of…

The cerebral cortex is formed up of overlapped and intertwined gray matter in the cerebrum of the brain. It is associated with the superior brain functions, coordination of sensory information, the capability to gain knowledge, the consciousness of being able to receive memory, along with the expression of originality, therefore playing an essential part in our consciousness. The cerebral cortex consists of very small layers of cells composed of billions of neurons as well as their endless…

Cerebral palsy is a group of permanent movement disorders that tend to develop in early childhood. The disorder originates in the cerebellum, which is located dorsally to the superior part of the brain and is composed of two hemispheres. In a healthy body, the cerebellum receives information from the spinal cord and then regulates motor movements. The cerebellum is composed of about half of the brain’s neurons. This does not mean that the disorder cannot develop in adulthood, however cases such…

right and the left hemispheres of the cerebral cortex. Even though these two hemispheres appear identical in terms of structure, they perform distinct functions. Split-brain studies and cognitive research has indicated that the left hemisphere is associated with functions such as language, conceptualization, analysis and classification. The right hemisphere is associated with art and music; special processing; face and shapes recognition. Popular belief is that the right hemisphere is capable of…

cells with one apical dendrite and multiple basal dendrites (Megias et al., 2001). The significant structures highlighted above would be examined and identified in the experiment using a light microscope and prepared slides of dog spinal cord, rat cerebral cortex, brain and…

Anatomy of cerebral cortex: Brain is most complex organ in human body. The ability of brain for its functioning normally is manifestation of various activities it takes participation in various activities of day to day life, being it hidden from the view or perceptible, like walking, smelling, thinking, laughing, speaking, and hearing. These manifestations are results of very coordinated and complex electrical and chemical activity within and between the cells those makes up our brain. Abnormal…

Cerebral Palsy is a disorder of the nervous system that is caused by abnormalities and damage to one or more specific areas of the brain. This damage occurs before, during, or immediately after birth when a child’s brain is developing. Research has determined what kind of brain and central nervous system damage occurs when someone has cerebral palsy as well as the symptoms that correlate with each injury and the effective treatment options to manage this chronic condition. Muscle coordination…

The Cerebrum is the biggest part of the brain and is responsible for important brain functions such as thought and action. The Cerebrum is separated into two hemispheres, the right and the left hemisphere. It is divided into four different parts: the frontal lobe, the parietal lobe, the temporal lobe, and the occipital lobe. (See annexe 1) The first lobe is the frontal lobe; the frontal lobe controls your creativity, your problem solving, your judgement, your intellect, your attention, your…
