The brain is composed of two types of cells, neurons and glial cells.
Brain tumors more commonly arise from glial cells, a type of supporting cell in the brain, rather than from neurons. Gliomas, which include astrocytomas, oligodendrogliomas, and ependymomas, are the most common types of brain tumors and originate from these glial cells. Neuronal tumors, such as gangliogliomas and ganglioneuromas, are less common.
The brain is composed of two types of cells, nerve cells and glial cells.
There are approximately 90-100 billion glial cells in the human brain, outnumbering neurons by 10 to 1. Glial cells provide support and protection for neurons, as well as regulate the brain's environment.

Generally, these would be the neurons and the supportive cells. Supportive cells, however, comprise several different kinds of cells. These include oligodendrocytes, glial cells, schwann cells, astrocytes, etc.
An immature nerve cell is called a neuroblast. Neuroblasts are precursor cells that will eventually mature into functional nerve cells, such as neurons or glial cells.
The cells that make up about half of the cells in the brain are called glial cells. Glial cells provide support and protection for neurons, the cells responsible for transmitting information in the brain. They also play important roles in maintaining the brain's overall health and function.
Glial cells were historically thought to provide mainly supportive functions to neurons, hence the term "forgotten." However, research over the years has shown that glial cells play crucial roles in modulating synaptic transmission, maintaining the health of neurons, and influencing brain development. They are now recognized as essential components of brain function.
Brain cells are classified as neurons or glial cells. There are 86 billion neurons and 10 to 50 times as many glial cells.
There is about 160,000,000,000 cells in human brain. Half of the number are neurons, which are rensponsible for all the "thinking" functions. The other half are "glial cells", which help neurons with their activity.
"Brain cell" is a term used to describe the neurons and glial cells present in the brain. brainandspinalcord.org
