The NHTSA reports that most accidents occur during rush hour, between 3 p.m. and 6 p.m. And according to the NHTSA, Saturday is the most dangerous day of the week to drive, primarily because there are more cars â and more drunk drivers â on the road than any other day.
They are also commonly known as neuroglia and even more simply glia. In more detailed terms, neuroglia are cells in your nervous system that are not neurons. Their role is to be the support team and cheerleaders for the neurons. The neuroglia: Form myelin, which wraps around axons to speed up electric impulse conduction ; Provide nutrients to your neurons, including oxygen ; Destroy pathogens ; Provide a general support structure on which neurons can sit ; In this lesson, we will focus on the neuroglia located in your central nervous system.
Neuroglia is the collective term for glial cells, specialized cells that protect and regulate the functioning of neural cells in the brain. In addition to promoting electrical communication between nerve synapses, some of these cells physically protect neural cells by surrounding them to form an insulating barrier.rain size also determines the number of cerebral neuroglia. Therefore, different species of animals contain varying concentrations of glial cells. The brain of a fruit fly, for example, is composed of 24 percent glia, compared to 90 percent in a human and 97 percent in an elephant.
