What else can I help you with?
Why are rapidly growing cancers that originate in nervous tissue most likely composed of neuroglial cells rather than neurons?
Neurones don't differentiate (divide). You'll have the same neurones when you die as you had when you were born (with a few exceptions). Glia can be created from immature cells called NGF2 expressing cells. This is why cancer affects glia; cancer starts when cell division goes wrong. Neurones don't divide so they don't get cancer (other than in very young children when new neurones are still produced), whereas NGF2 cells do, so they can become cancerous.
What is the size of a neuron compared to other cells?
Neurons are generally larger than many other types of cells in the body, with a typical diameter ranging from 10 to 100 micrometers, depending on the type. Their unique structure includes a long axon and numerous dendrites, which facilitate communication with other neurons. While some cells, like muscle cells, can also be quite large, neurons are distinctive for their complexity and specialized functions in transmitting signals. Overall, neurons are among the largest and most complex cells in the human body.
Is Vacuoles smaller or larger in plant cells rather than animal cells?
It Is Larger!!
Are proteins larger than blood cells?
Yes,because proteins is like egg is larger than blood cells.
Are virus's larger than cells?
No. They are over 1,000,000 times smaller than cells!!
Are some cells larger than other cells?
Yes, some cells are larger than others. The size of a cell can vary depending on its function and type. For example, eggs are some of the largest cells in the human body, while red blood cells are much smaller.
What is the collection of neurons and glial cells that control all major functions of the body?
That organ is called as brain. You have more than 100 billion neurons in your brain.
Is true that small cells have larger surface area to volume rations than do larger cells?
Cell have a greater surface area to volume rations than a larger cell.
Are virus particles larger than cells?
No. They are over 1,000,000 times smaller than cells!!
What are smaller than cells but larger than atoms?
Molecules are smaller than cells but larger than atoms. They are composed of atoms bonded together to form a distinct structure.
Are eukaryotic cells larger than prokaryotic cells?
They generally are due to the fact that they are much more complex than prokaryotic cells, but there are some very small Eukaroytic cells (such as the sperm: 40 microns), that are smaller than some large Prokaryotic cells (the largest found so far is 660 microns long). As a rule of thumb, though, Eukaryotic cells are larger than Prokaryotic cells.
Which Are Bigger Prokaryotic or eukaryotic cells?
Eukaryotic cells are generally larger than prokaryotic cells. Eukaryotic cells have a more complex structure with membrane-bound organelles like the nucleus, while prokaryotic cells lack these organelles. This allows eukaryotic cells to grow larger in size.
