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.
Glial cells are also called neuroglia or glia, which is Greek for glue.. The two main types of cells in the nervous system are glia and neurons. Glial cells are non-neuronal cells which provide support, protection and nutrition for neurons, as well as maintain homeostasis and form myelin. Not all astrocytes contact brain capillaries. Astrocytes are actually the cell population in the brain which are left over after neurons, oligodendrocytes and microglial cells are removed. Subsequently, astroglial cells display a heterogeneity in their morphology and function.
