Meninges

Blood Brain Barrier One of the most important properties of BBB is that it separates the brain tissue from the blood circulation of the CNS. By that it consists of three parts: the layer of endothelial cells connected through tight junctions, basal membrane, and astrocytes and pericytes. Its main function is it only select molecules to pass from the bloodstream into the fluid that bathes the brain, whereas vital nutrients get in, toxins and pathogens are blocked. Formed by endothelial

Hydrocephalus Definition A condition affiliated with excessive fluid in the brain. Causes, incidence, and risk factors The fluid in the brain (cerebrospinal fluid or CSF) is formed in the brain. CSF usually circulates through parts of the brain, its covering, and the spinal canal, and is then absorbed into the circulatory system. When the circulation or absorption of this fluid is blocked, or excessive fluid is produced, the volume of fluid in the brain becomes higher than normal. The accumulation

Kaitlyn Cook, Arianna DeNault, Cayla Burton, Jessica Debuyser, Matt Cole, Brian Bishop Health paper Wellness 12:20 October 5th, 2016 Meningitis and steroids can become major issues. There are many different types of meningitis and steroids. Some different types of meningitis are viral and bacterial, fungal, parasitic and noninfectious meningitis. Bacterial meningitis is a potential life threatening of the disease that can cause problems with the brain including possible death if not properly treated

March 3rd 2015 Biology I Ms. Haynie Viral Meningitis Meningitis is an inflammation of the membranes surrounding your brain and spinal cord. The swelling associated to viral meningitis also has symptoms including headache, fever and a stiff neck. Most cases of meningitis are caused by a viral infection, bacterial and fungal infections also can lead to meningitis. Depending on the cause of the infection, meningitis can get better on its own in a couple of weeks, or it can be a life-threatening emergency

Subdural Hematoma Evacuation Subdural hematoma evacuation is a procedure used to treat a collection of blood (blood clot) between your brain and its tough outer covering (dura). The blood clot is caused by bleeding (hemorrhage) from a torn vein. Subdural hematoma evacuation is sometimes done for bleeding that develops slowly, over weeks or months (chronic subdural hematoma). The procedure may be needed if the bleeding becomes dangerous or presses on the brain. It is also sometimes done as an emergency

Bacterial meningitis is an infection that originates in the meninges of the brain and can spread into the spinal column. The symptoms can develop within hours and take up to two days after encountering a carrier host. Bacterial meningitis can be transmitted through fluid transmission from the mouth or throat of an infected person. Bacterial meningitis is a gram-negative meningitis diplococcal bacterium. There are several bacteria types that can cause meningitis, which include Streptococcus pneumoniae

is the inflammation of the meninge layers of the central nervous system (the pia matter, arachnoid matter, and the dura matter). This disease in most cases is caused by these five microbes: - Neisseria meningitis - Streptococcus pneumoniae - Haemopilius influenzae - Listeria monocytogenes - Streptococcus agalactiae The CNS is a bacteria free zone so these microbes could have invaded the body through a rip or tear in the meninges, a break in a bone surrounding the meninges, a non-aseptic spinal tap

for the intellectual, emotions, behavior and memories (Tortora and Derrickson, 2011). The brain is covered by meninges layers consisting the dura mater, the arachnoid mater and the pia mater. The dura mater forms the outermost layer of meninges that act as a protective and supportive if the brain. While the arachnoid mater and the pia mater form the middle and the innermost layer of meninges respectively. Furthermore, the subarachnoid space lies between the arachnoid and pia mater responsible for circulation

The general structure of the nervous system is known as the “anatomy of the nervous system” (neuroanatomy). The acts of human beings are guided by controls through the nervous system. A human being’s response to its environment is also through controlled guiding and thoughts (Pinel, 2013). The peripheral nervous system or PNS and central nervous system or CNS are important parts of our nervous systems within hollow tube holding the CNS and PNS of our nervous system (Pinel, 2013). There are subdivisions

Myelomeningocele. Spina Bifida Occulta is one or more vertebrae are not properly formed. In Closed Neural tube defects it consists of a diverse group of defects in which the spinal cord is marked by malformations of fat, bone, or meninges. Meningocele is spinal fluid and meninges protrude through an abnormal vertebral opening. And Myelomeningocele is the most severe and occurs when the spinal cord/neural elements are exposed through the opening in the spine, resulting
