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.
The human nervous system consists of billions of nerve cells (or neurons)plus supporting (neuroglial) cells. Neurons are able to respond to stimuli (such as touch, sound, light, and so on), conduct impulses, and communicate with each other (and with other types of cells like muscle cells).
