Opa and Opc proteins mediate these interactions, which occur also on endothelial and epithelial cells. Individuals living and working in crowded areas are at increased risk of meningitis. The supply of blood to the brain is crucial to its ability to perform many functions. The mechanism by which meningococci penetrate this leptomeningeal coating is unclear, but the fact that meningeal cells do not internalise meningococci suggests intercellular penetration, perhaps as a consequence of degradation of desmosomes and other junctions by endothelial cell metabolites. Due to the lack of arachnoid granulations during foetal life, it is most likely that CSF is eliminated by lymphatic drainage pathways passing through the cribriform plate and nasal submucosa. The most important of these is the middle meningeal artery, which can be damaged by head injury and has clinical significance.

Accepting the NEJM cookie is necessary to use the website. For a recent review see. The soma also produces an elongated extension, called the axon, which is responsible for the transmission of electrochemical signals through elaborate ion transport processes. The redirect does not point at a valid page. The drawing depicts the leptomeningeal layer as the perivascular cuff continuing with the vessel as it penetrates the brain substance. Blood supply of spinal cord arise from one anterior and two posterior spinal arteries supplemented by segmental or radicular arteries.

Once the facial nerve reaches the face it enables many functions, such as facial expression, secretion of glands and taste sensation. This observation is consistent with the notion that the regenerating axons responded to cues similar to those that operate during development. Viral meningitis improves on its own within several weeks. Why does cerebral cortex fissure and fold? IV access to medical staff immediately.
The reasons why is indicated by replacement of pia mater covers the ablation
However, regulation of this permeability is achieved through the abundant amount of astrocyte foot processes which are responsible for connecting the capillaries and the pia mater in a way that helps limit the amount of free diffusion going into the CNS.
