Meninges

Meningitis is caused by the swelling of the membranes that encircles around the spinal cord and brain. The disease is generally triggered by infection of parasites, fungi, bacteria, viruses, and particular organisms. Weak immune systems may be also connected to recurrent bacterial meningitis although most meningitis cases are caused by viruses. The disease mainly affects the central nervous system which consists of the brain, nerves and the spinal cord. Symptoms such as the fever may be the…

Although this can be a tough disorder with possible physical and mental disabilities, with the correct treatment and follow through many people with some assistance cam live their lives fully.

vessels), in the cranial nerves (myelin-producing Schwann cells), in the brain envelopes (meninges), skull, pituitary and pineal gland, or spread from cancers primarily located in other organs (metastatic tumors). Brain tumors are of two types: primary and secondary. Primary brain tumors include any tumor that starts in the brain. Primary brain tumors can start from brain cells, the membranes around the brain (meninges), nerves, or glands. Primary brain tumors are classified as: 1) benign; 2)…

The spinal cord is ¾ of an inch wide and 42-45 centimeters in length. It extends inferiorly from the medulla oblongata to the inferior border of the L1 vertebrae. The spinal cord is divided into 5 parts that house the 31 pairs of spinal nerves. The cervical part is the superior part of the spinal cord. It contains neurons whose axons contribute to the 8 pairs of cervical spinal nerves. The thoracic part lies inferior to the cervical part. It houses the neurons for the 12 pairs of thoracic spinal…

Meningococcemia is caused by a gram negative bacteria which infects the bloodstream, and is caused by the Neisseria meningitidis bacterium. There are two forms of this illness: Meningococcal Meningitis, which occurs when the meninges become infected and swell; and Meningococcal Septicemia, occurs when the bacteria multiply in the bloodstream causing damage to the blood vessels, causing internal bleeding. Septicemia is the more serious form. Individuals at risk include people in daycare,…

The condition is usually developed by contact with the infected skin with the bacteria. It is often a crusty, red,…

can be a life-threatening emergency requiring urgent antibiotic treatment. Acute bacterial meningitis usually occurs when bacteria enter the bloodstream and migrate to the brain and spinal cord. It can also occur when bacteria directly attacks the meninges, as a result of an ear or sinus infection, or a skull fracture, or rarely, after some surgeries. Each year, viruses cause a more number of cases of meningitis than do bacteria. Viral meningitis is usually mild and often clears on its own. A…

the open head trauma or penetrating head trauma, however, there is penetration of the skull, thus leading to direct damage to the brain. This damage can occur to any part of the brain such as rupture of the dura mater, the outermost layer of the meninges. An open head injury is more likely to be caused by high velocity missile than low velocity objects,…
