Neurons, Brain, and Nerves Oh My! An introduction to the Nervous System


To understand the nervous system we'll start with a microscopic explanation of what composes nervous tissue. We'll then discuss all the macroscopic divisions.

Microscopic Description:
There are two kinds of cells that compose nervous tissue of the body: neurons and glia. Neurons are the information processing cells. They speak with each other through electrical and chemical means. Electrical communication in the neurological system is achieved through "action potentials". Action potentials are transformed into a compound point at the "synapse", and that is the spot where 2 distinct neurons communicate with each other.
Glia, on the contrary, are the supporting cells. You will find many different types of glia, all of which have a variety of functions. For example, glia known as oligodendrocytes help insulate neuronal axons so that electrical communication in the brain and spinal cord is quick & economical. Astroctyes, another type of glia, are accountable for ensuring the blood brain barrier. In addition, they maintain the integrity of the substance atmosphere around neurons. Yet another type of glia, ependymal cells, line the ventricles, or Maximum Strength Neuropathy Support Formula fluid filled cavities of the brain. It's crucial to realize that there are various other types of glia with very important functions.
Whenever we put together several millions of neurons as well as glia into structural units we arrive at the cause for defining the central nervous system at a macroscopic fitness level.

Macroscopic Description:
The neurological system is often broken into two different divisions based on anatomical location. These sections are the main nervous system (CNS) plus the peripheral nervous system (PNS).

CNS: Brain along with Spinal Cord

CNS: Brain and Spinal Cord

PNS: somatic and Autonomic Divisions
