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.
A neuron (/ËnjÊÉrÉn/ NYEWR-on or /ËnÊÉrÉn/ NEWR-on, also known as a neurone or nerve cell) is an electrically excitable cell that processes and transmits information through electrical and chemical signals. These signals between neurons occur via specialized connections called synapses.
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.
