Meninges

How do Meningiomas Affect the Brain? Meningiomas are typical kind of tumor that begins in the nervous system. Though they are called brain tumors, they actually grow on the three layers of meninges of the brain and spinal cord. Meningiomas tend to grow in the meninges of the brain, but can occur in the meninges of the spinal cord. The meninges are the tissue that protects the brain and spinal cord. The cause of meningiomas is not well understood, but could be from genetic and environmental factors. They are more common in mid-aged women but men do get them too, and they are very rare in children. Many brain tumors are diagnosed to be cancerous, but meningiomas are noncancerous ninety percent of the time. Some meningiomas may first be diagnosed as benign but become malignant over time. When the tumors become cancerous they will be treated with the techniques used against cancer. But when they are benign and without symptoms, only routine monitoring is recommended. Regular scans should be done to monitor changes in growth.…

My paper is composed of various articles I have researched and analyzed. The sources are both internet and textbook. Through analysis of the data I will provide the bases of my findings of meningitis and how it affects the body, how it is diagnosed, treated and how it can be prevented. Meningitis is an infection of the meninges, which is detrimental to the central nervous system, as such creates an imbalance in homeostasis. Since the brain is the control center of the body, if a problem develops…

that it thebrain loses some of its functions for a couple of days or weeks depending on how serious the concussion is. A concussion is an injury that you cannot see which is why some people calls it an invisible injury because you can get hit in the head very hard and not have any bruises or cuts on your head but you would still have a concussion because you would later feel the symptoms coming. The brain is surrounded by a fluid and protective membranes that separates the skull from the brain…

the brain gives us frontal sections which run in the same direction as the forehead. The sagittal section makes the brain run even with the neuraxis and perpendicular to the ground. That right angle formed to ground creates the midsagittal plane which cuts the brain into two symmetrical halves the left and right half. The horizontal section divides the brain into top and bottom parts and runs even with the ground. The coronal section is the front and back of the brain, the sagittal section is…

Bacterial Meningitis Meningitis is an infection that affects meninges, membrane coverings of the brain and spinal cord. Due to Bacterial meningitis’ close proximity to the brain and spinal cord it is potentially life threatening. If not treated promptly it may lead to life-long complications such as deafness, epilepsy, hydrocephalus and cognitive deficits. Bacterial meningitis is contagious and prolonged close contact can spread the bacteria that cause meningitis. The bacteria can spread from…

Meningitis is inflammation of the meninges. These meninges surround the brain and spinal cord which is very dangerous as Inflammation in these areas can affect your whole body and because it to stop working. This can also occur due to injury in the certain parts of your head. Bacterial meningitis is not as common as viral meningitis. But it is more dangerous than viral meningitis, it could even possibly be life-threatening without being promptly treated it can lead to many very serious…

Meninges is the membrane that covers the brain. Therefore, meningitis disease is an infection that targets that membrane. It also infects the spinal cord and can cause swelling. Meningitis is a very quick infection often leads to death or other forms of disabilities such as mental retardation, epilepsy, deafness etc. if not treated. CAUSES TRANSFER Many bacteria can lead to meningitis, however, Neisseria meningitides is the most known as it poses the potential to cause epidemics on a large…

Blood was thought to be the primary transporter of the immunity cells to and from the brain (Louveau et al., 2015). Previous studies had, in fact, discovered that the cerebrospinal fluid (CSF) was was transported to the deep cervical lymph nodes, but the mechanism was scantily understood (Louveau et al., 2015). Coincidentally, Dr. Kipnis and colleagues were trying to determine the route of immune cells’ entrance and exit from the CNS to the systemic circulation when they discovered the meningeal…

Bacterial Meningitis, Adult Bacterial meningitis is a serious infection that affects the membranes that line the brain and spinal cord (meninges). Bacterial meningitis needs to be treated as soon as possible. The infection can get worse quickly and cause permanent brain damage and long-term problems such as seizures and hearing loss. CAUSES This condition is caused by bacteria. You can get this condition if fluid from an infected person's nose, mouth, or throat: Gets into your brain…

In the case of meningitis the infectious organism must overcome the body’s nonspecific and specific defenses that are in place such as, the skin barrier, blood-brain barrier, nonspecific inflammatory response and the specific immune system response (LeMone, 1498). When an infection of the CSF and meninges occurs it causes an inflammatory response in the pia and arachnoid matter. The meninges and subarachnoid space cover the brain and spinal cord therefore, any infection will ultimately reach…
