Oligodendrocyte and microglia brain cells

Oligodendrocyte and microglia action in the brain. At top, the axon (output process, orange) of a neuron (nerve cell) is seen. It is being enclosed by processes originating from a neighbouring oligodendrocyte cell (red). This provides a sheath of the fatty chemical myelin, which improves the conduction of the nerve signal. At bottom, microglia cells (green) are seen around a blood vessel. Microglia are the immune cells of the brain, and they are inspecting damage in the blood vessel wall. They can engulf any foreign bodies they detect, preventing them from damaging the brain cells

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate workings of oligodendrocyte and microglia brain cells. At the top, we witness the remarkable collaboration between an oligodendrocyte cell and a neuron's axon. The vibrant orange axon, responsible for transmitting signals, is enveloped by processes originating from a neighboring red-hued oligodendrocyte cell. This process creates a protective sheath made of myelin, a fatty chemical that enhances nerve signal conduction within our complex neural network. Moving to the bottom of the image, we encounter microglia cells in their vigilant role as guardians of our brain's well-being. These green-colored immune cells encircle a blood vessel, diligently inspecting its walls for any signs of damage or foreign bodies that could potentially harm delicate brain tissue. Microglia possess an incredible ability to engulf and neutralize any detected threats, acting as an essential defense mechanism against potential harm. Through this stunning illustration, we gain insight into both the anatomical and physiological aspects of these crucial brain cells. It serves as a reminder of how intricately interconnected our nervous system is with our immune system - working tirelessly together to protect and maintain optimal functioning within this vital organ: our brain.
