Holger Hyden, for example—a reputable biochemist and neuroscientist—stated more decisively in the 1960s that there are ten times as many glial cells as neurons. It’s probably the case that Hyden based his proclamations on specific regions of the brainstem he was studying where glia really ...

Of 100 billion nerve cells in the human brain, how many form after birth For years, the official answer was "zero". Scientists thought people were born with all the neurons they’d ever have. But from 1980s, biologists overturned that doctrine, finding a reservoir of stem cells that becam...

In addition, many people think that all that extra brainpower leads to eccentric or quirky behavior. And although geniuses are fairly easy to spot, defining exactly what makes one person a genius is a little trickier. Figuring out how that person became a genius is harder still. There are ...
How many parts are in a plant cell? What is the nuclear membrane in an animal cell? What happens when you stimulate the middle of a neuron? What is the role of glial cells in nervous tissue? What is bulk transport cell membrane?
A typical brain contains something like 100 billion minuscule cells called neurons (no-one knows exactly how many there are and estimates go from about 50 billion to as many as 500 billion). [1]Each neuron is made up of a cell body (the central mass of the cell) with a number of ...
If you hear your doctor or nurse talk about a “malignant” tumor, that means it’s cancer. A “benign” tumor isn’t. The kind of treatment you get depends on that key difference, along with many other things. Here are some of the types of tumors and a little about each of them:...
Vitamin C is found in citrus fruits such as oranges, limes, and grapefruit, and vegetables including tomatoes, green pepper, potatoes and many others. Vitamin C is easily damaged during the food preparation stage, such as during chopping, exposure to air, cooking, boiling, and being submerged...
Why do skeletal muscle cells need so many nuclei? How do the structures of dendrites and axons suit their functions? What are some unique characteristics of the cardiac muscle cell? How does the cardiac muscle cell work with other cells/ tissues/ organs to achieve its...
