Meninges

evidence of a preexisting, less-malignant precursor lesion), presenting after a short clinical history, usually less than 3 months. Secondary glioblastoma multiformes (40%) typically develop in younger patients ( cells of the arachnoid villi in the meninges. These tumors usually are benign in nature; however, a small percentage of these tumors are cancerous. Choice “D” is not the best answer. Ependymoma is a tumor that arises from the ependyma, a tissue of the central nervous system. Usually, in pediatric

case, there are tests that doctors can utilize in order to discover if the meningitis is bacterial, fungal, or viral. Meningitis is a contagious infection of the cerebrospinal fluid and inflammation of the meninges, the nearby membrane that covers the spinal cord and brain. Both the meninges and cerebrospinal fluid serve as protectors

They occur when the neural tube does not fuse completely, leaving an opening in the skull. The opening may be positioned in the upper portion of the skull, the frontal area involving the face, or the back of the skull. These herniations contain meninges and frequently brain tissue. . There are many factors thought to be involved in the cause of encephalocele. Family history of spina bifida and anencephaly are thought to be contributing genetic factors. Exposure to certain environmental toxins

Meningitis: Viral and Bacterial Meningitis is an inflammation of the meninges, membranes that surround the brain. This can extend as far as infecting the cerebral spinal fluid on top of causing the tissue to swell. Meningitis comes in two major forms; bacterially and virally. However, having bacterial meningitis is much more severe than viral meningitis. There is a lot more danger in having a bacterial infection within the brain than a viral infection within the brain. What makes bacterial meningitis

Is meningitis contagious to pregnant women? Meningitis is a rare infection of the membranes covering the brain and spinal cord called as meninges. It is of 3 types- • Viral- less severe and people generally recover completely • Bacterial- It is dangerous and contagious among people in close contact • Fungal- Very rare and in people with low immunity Discussion Bacterial- It is very serious. Can lead to death or permanent damage to brain and other parts of body. It is spread from person to person

is related to blood vessel damage. Seizures and dizziness are some of the physical symptoms. We can rule out traumatic brain injuries like fluid buildup in the brain that could cause the brain to swell; skull fractures or wounds that can tear the meninges pooling blood outside the vessels and enabling the bacteria to infect the nervous system. 2-Seizures

types of hematomas, depending on where the hematoma develops. According to the 2016 report issued by the Centers for Disease Control and Prevention (CDC), “different types of hematomas form depending on where the blood collects relative to the meninges. The meninges are the protective membranes surrounding

It is an acute inflamation of the protictive membrane in the brain and spinal cored, known collectively as the Meninges. B. The inflammation can be cause by infection within the viruses, bacterias or orther micro organism or even drugs. C. It can be life-threatining because the inflammation is in the brain and spinal cord. III. Types of Meningitis Diseas A. Viral

and peripheral nervous system (PNS). The central nervous system (CNS) is the largest part, and includes the brain and spinal cord. The spinal cavity contains the spinal cord, while the head contains the brain. The CNS is enclosed and protected by meninges, a three-layered system of membranes, including a tough, leathery outer layer called the dura mater. The brain is also protected by the skull, and the spinal cord by the

disease is the critical reason for increasing morbidity rates in young children under the age group of one year. In the last 20 years (1991–2010) close to one million suspected meningitis cases were reported in the UK and in the US. [8] [5] The ‘meninges’ is the name for the three membranes that envelope the brain and cord (the central nervous system). Bacterial meningitis is caused by three different bacteria’s: Haemophilus influenzae type b, Neisseria meningitidis, and the Streptococcus pneumoniae
