There are 100 billion neurons in th human brain and about 1-5 trillion glial cells (that's 10-50 times more!). Most are astrocytes.
Fluorine is used in many substances, including fluoride that is pumped into the water supplies of many cities because of the scientific evidence that fluoride prevents cavities in people's teeth.
Specialized cells are found only in Gonads ( reproductive cells ).
gametes typically have exactly one half the number of chromosomes of body cells. This makes sense because two gametes are combined through fertilization to make a new cell with a full set of chromosomes. In some instances, the gamete has an extra chromosome because the chromosomes don't segregate properly during meiosis. This causes a condition called trisomy, and can cause disorders like down syndrome

There are three convection cells in the southern hemisphere. There are also three convection cells in the northern hemisphere, making a total of six on the face of the Earth.
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.
There are many neurons in the human brain (~ 100 billion) but glial cells outnumber neurons by 10 fold. Therefore, the most abundant cell type in our brain would be glial cells of which astrocytes (a type of glial cell) is the most numerous. http://en.wikipedia.org/wiki/Neuron
The primary cell in the brain is the neuron. There are also many supporting cells, such as astrocytes, glial cells and the like.
The adult human brain typically contains around 86 billion nerve cells, or neurons. Additionally, the brain contains other types of cells called glial cells, which may outnumber neurons by up to 10 to 1. Overall, the brain is composed of a vast network of cells that work together to control bodily functions and processes.
There are over 400,094,800 cells in the human brain, while the entire body has about 50 to 75 trillion cells.

There are approximately 100 billion neurons inside a human brain.

Scientists have organized the cells that make up the nervous system into two broad groups: neurons, which are the primary signaling cells, and glia, which support neurons in various ways. The human brain contains around 100 billion neurons and, by most estimates, somewhere between 10 to 50 times as many glial cells. Bipolar ones are usually found outside the brain and interneurons are found within the brain.
