Critical reading means engaging in what you read by asking yourself questions such as, âwhat is the author trying to say?â or âwhat is the main argument being presented? Critical reading involves presenting a reasoned argument that evaluates and analyses what you have read.
Glial cells, sometimes called neuroglia or simply glia (Greek Î³Î»Î¯Î± and Î³Î»Î¿Î¯Î± glue; pronounced in English as either /ËÉ¡liËÉ/ or /ËÉ¡laÉªÉ/), are non-neuronal cells that maintain homeostasis, form myelin, and provide support and protection for neurons in the central and peripheral nervous systems.
Here are some examples of nervous tissue: 1  Gray matter-cells without insulation, tightly packed in your brain and in the inner part of your spinal cord. 2  White matter-cells insulated by a substance called myelin. 3  Neuroglial cells-these cells support and nourish the nerve cells.he nervous system is not just built from neurons. There are also cells that don't communicate, but wrap around the neurons to nourish and protect them, called Schwann cells. The organs of the nervous system work together to coordinate body processes.
