Meninges

harm or damage. The protective membranes that surround the brain and spinal cord are called the meninges. The meninges consist of three layers, the dura mater, arachnoid mater and pia mater, which all provide protection against bacteria and other threats. If an infection occurs in the cerebrospinal fluids surrounding these membranes, the meninges suffer from inflammation. This swelling of the meninges can range…

Meningitis is a bacteria or infection that causes the meninges to swell. Meninges are three membranes that are call; the Dura mater, Arachnoid, and Pia mater. These membrane layers are to protect and cover the brain and spinal cord. The meningitis infection or bacteria would seek through the bloodstream to the brain causing inflammation. Meningitis can also occur by ear infection and sinus infection. Meningitis can affect in all different types of ages, but can most commonly affect one certain…

Gaucher’s disease is a rare genetic disorder in which when a person lacks of enzyme called glucocerebrosidase. The genes that are involved are GBA(glucosidase, beta, acid) genes. The GBA genes are the ones that provide instructions for making enzyme which is called beta-glcocerebrosidase. There are 4 types of Gaucher’s disease. Type 1 Gaucher’s disease is the most common form of this condition. Type 1 Gaucher’s disease doesn’t really affect the brain or the spinal cord (central nervous system)…

Myelomeningocele is the most common and most serious form of spina bifida. It is a neural tube defect in which the bones of the spine do not completely form and an incomplete spinal canal is the result. Although myelomeningocele is most common in the lower back, it can happen anywhere along the spinal cord (Myelomeningocele, n.d.). This can affect as many as 1 out of every 4,000 infants. (Myelomeningocele, 2015) To better understand myelomeningocele, is to understand the causes and how it…

Meningitis is a disease caused by the inflammation of the protective membranes covering the brain and spinal cord, known as the meninges. The inflammation is usually caused by an infection of the fluid surrounding the brain and spinal cord. Meningitis can result from a variety of sources, such as bacteria, viruses, fungus, or parasites; it can also be caused by a physical injury. Treatment for meningitis differs depending on the cause and the severity. So it is imperative to know the cause…

Introduction When a cough isn’t just a cough and may in fact be fatal. Whooping cough is that cough, the one that you should hope never to encounter. The Wichita Eagle states that there were three cases diagnosed in Kingman, county, Kansas. I wondered why this would make the news. Three cases do not sound like much to worry about, however, by the end of the article I realized this is indeed something that should be taken seriously and was indeed newspaper worthy. The article introduces us to…

An Arteriovenous Malformation (AVM) can be described simply as a tight rubber band ball of abnormal blood vessels with weak walls. These can be located anywhere in the body. Arteries carry blood containing oxygen from the heart to the brain. An AVM bypasses normal brain tissue and directs blood from the arteries to the veins without a capillary bed in between. Brain AVM’s occur in less than one percent of the population (per 100,000 people) and are more common in males than females. Being…

Encephalocele, or also known as Cranium Bifidum is a rare type of birth defect of the neural tube that affects the brain. The neural tube is a narrow channel that folds and closes during the third and fourth weeks of pregnancy to form the brain and spinal cord. Encephalocele is a sac-like protrusion or projection of the brain and the membranes that cover it through an opening in the skull. Encephalocele happens when the neural tube does not close completely during pregnancy. The neural tube is a…

In the human composition the functions of the body and mind are dictated by the nervous system. There are two parts of the nervous system the peripheral nervous system and central nervous system. The brain, spinal cord, and nerves is what the nervous system is composed of. Together they control all the duties of the body. When something goes wrong with a part of your nervous system, you can have issues with actions such as breathing,speaking,swallowing, and moving. It is effortlessly the…

attack microbes. (3.) Ependymal cells are cells that covers and lines the surfaces and cavities. (4.) Oligodendrocytes are cells that makes myelin that holds the nerve fibers in place. What doe the term meninges mean? What are the 3 distinct layers of the meninges? Discuss this in detail. Meninges is membrane…
