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 are also important for the protection of neurones in the brain, and there are almost the same number of neuroglia cells as the number of neuron cells in the human brain. The structure of this cell is like a spider or an octopus, but there is no axon as in neurons. Neuron has an axon but, not in neuroglia. â¢ Neuroglia form myelin but those are present and functional in the axon of neurons. â¢ Neuroglia form packaging media between nerve cells in the brain and spinal cord and but not the neurons.
