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.
The other cells, neurons, act as the communicators of the nervous system. Neurons receive information, integrate it, and pass it along. They communicate with one another, with cells in the sensory organs, and with muscles and glands. Each neuron has the same structure:1  Each neuron has a soma, or cell body, which is the central area of the neuron.2  It contains the nucleus and other structures common to all cells in the body, such as mitochondria. Axons send information to other neurons, to muscle cells, or to gland cells. 2  What we call nerves are bundles of axons coming from many neurons. 3  Some of these axons have a coating called the myelin sheath. 4  Glial cells produce myelin, which is a fatty substance that protects the nerves.
