protected by a bony covering called the skull. The base‚ or lower part‚ of the brain is connected to the spinal cord. Together‚ the brain and spinal cord are known as the central nervous system (CNS). The spinal cord contains nerves that send information to and from the brain. The CNS works with the peripheral nervous system (PNS). The PNS is made up of nerves that branch out from the spinal cord to relay messages from the brain to different parts of the body. Together‚ the CNS and PNS allow a

Paralysis occurs when poliovirus enters the central nervous system through the peripheral nerves or during viremia. The paralysis is usually in the legs‚ but poliovirus can cause total paralysis in a matter of hours. Poliovirus has a protein capsid which is 28 to 30nm thick and contains 12 capsomeres. It

Dementia is a type of disorder that affects the central nervous system. It’s not a disease itself but a group of symptoms that characterize disease and conditions. It’s commonly defined as a decline in intellectual functioning that is severe enough to interfere with the ability to perform routine activities. It causes significant loss of intellectual abilities‚ such as memory capacity‚ severe enough to interfere with social or occupational functioning. Dementia‘s a general term that also includes

The interaction of mind and consciousness with the body‚ and whether they are separate or not has been the subject of much discussion and debate between philosophers since antiquity. This paper shall look at how dualists‚ materialists and idealists view the realm of mind and consciousness and how the realm of mind and consciousness relate to the physical body. Additionally‚ the concept of an independent mind that transcends physical functions of the body shall be discussed along with the author

Meningioma A Meningioma is a tumor of the central nervous system that develops from cells of the meninges (the Dura matter‚ arachnoid‚ and pia matter) and spinal cord. In most cases 90% of Meningiomas are benign (non-cancerous) and do not tend to spread out to the rest of the body or nervous system. These tend to grow at a very slow rate and usually show no symptoms until the tumor gets relatively large. This is due to the gradual compression of the brain over time. Although benign

Neurologist What is a Neurologist? A neurologist is a medical doctor who is skilled in the diagnosis and treatment of nervous system disorders‚ including diseases of the brain‚ spinal cord‚ nerves‚ and muscles. They perform neurological examinations of the nerves in the head and neck‚ muscle strength and movement‚ balance and reflexes‚ and sensation‚ memory‚ speech‚ language‚ and other abilities. They also perform diagnostic tests such as: CAT Scan MRI/MRA Spinal Tap Education Requirements

The clinical disease occurs when the virus begins to replicate on site of the bite and the proceeds to enter the blood stream and begins attacking the central nervous system. While cases in humans and horses are rare‚ it is important especially in our region where the vectors are active‚ to know the method of transmission‚ common vectors and hosts‚ as well as the maintenance and spread of the EEEV and WEEEV.
