Types of cells in the brain Human Body Glial

Type of  CELLS in the Human Brain Body GLIAL
Glial cells make up 90 percent of the brain's cells. Glial cells are nerve cells that don't carry nerve impulses. The various glial (meaning "glue") cells perform many important functions, including: digestion of parts of dead neurons, manufacturing myelin for neurons, providing physical and nutritional support for neurons, and more. Types of glial cells include Schwann's Cells, Satellite Cells, Microglia, Oligodendroglia, and Astroglia.

There are many type of neurons. They vary in size from 4 microns (.004 mm) to 100 microns (.1 mm) in diameter. Their length varies from a fraction of an inch to several feet.

Brain tumor symptoms wiki
Symptoms of a brain tumor?
particuarly bad headaches, sight goes blurry, nausea but not actually throwing up, lack of appetite, occasional fits. pain at the back of the neck but these symptoms are common symptoms of non fatal illnesses too. it is unlikely that they will lead to a brain tumour unless you have two or more of them at the same time. But even then its most likely you have a migraine

Brain tumor specimens taken from neurosurgery cases at the University of California, San Francisco (UCSF) Medical Center has given scientists a new window on the transformation that occurs as healthy brain cells begin to form tumors.

Malignant Tumor Cells info
Malignant tumor cells are cancerous cells that spread and multiply, causing malignant tumors. A malignant tumor is an abnormal mass of tissue that is created due to the uncontrolled speed of cancerous cell division.
 Tumors can be classified in benign and malignant tumors. While a benign tumor is non-lethal and has a slow grow rate, malignant tumors are cancerous masses that expand very quickly and, because of their high metastasize rate, they can spread to other areas of the body, causing cancer to develop in those areas too.
