The Brain’s Connective Tissue System
(Workbook Page 30)
Astrocytes, microglia and oligodendrocytes are cells collectively known as glia.
This animation demonstrates the various glial cells and the inflammatory reaction to a foreign particle crossing the barrier between the brain and body.
Ninety percent of all brain cells are glia. Structurally, they create the matrix that suspends the nerve cells in the brain. Their purpose does not stop there. The glia coordinate function, facilitate communication between brain and body and monitor and modify input and output. The graphic on page 30 of the Neuroplastic Transformation workbook depicts the various brain cells. All glia have counterpart cells in the body that interact similarly to the way the glia interact in the brain. The glial cells are part of the connective tissue system that exists throughout the entire body.
Chronic inflammatory processes begin in the same manner as acute inflammation, but several factors lead to long term potentiation in nerve cells in the pain pathway in the brain. As a result a glial cell (Astrocytes and microglia) inflammatory process is initiated leading to creation of more Substance-P in persistently firing nerve cells .This, in turn, causes the pain map to expand in the brain and release of Substance-P and several other inflammatory products into the injured tissue, overwhelming the anti-inflammatory response. This establishes a loop between brain and body that perpetuates the experience of pain, while preventing proper healing.
The nervous system is classically viewed as the way the brain and body are connected. In reality the Nervous System and the Connective Tissue System are one system that elegantly orchestrates communication allowing for instantaneous processing of input and output.
