What are nerve cells often called?
Nerve cells are often called neurons.
Why nerve cell long and thin like a wire?
People often refer to nerve cells as wires, as they carry electrical impulses through them, like a wire would carry similar data.
Why might Cells from an advanced malignant tumor most often have very abnormal chromosomes and often an abnormal total number of chromosomes?
Chromosomally abnormal cells can still go through cell cycle checkpoints.
Which in DNA often occur during replication. During which phase of the cells cycle do such mutations occur?
Interphase
Can bacteria grow at the same rate?
No they don't. For example-the cells on the inside of your mouth are constantly being rubbed away when you eat or chew or even talk. So the cell cycle for these cells is quite fast. Also, the cells in your stomach actually are eaten away by the acid there. Those cells need to be replaced constantly. On the other hand, the bone cells in your collar bone or in your skull are not worn away often if at all and the cell cycle for those is very long. Some cells are never replaced once they are made, such as nerve tissue. That is why if your spinal cord is severed you are paralyzed forever.

Why can you often not feel third degree burns?
It is often painless because it kills your nerve cells. As a result, your nerve cells can't send pain signals.
How often do nerve and muscle cells divide?
Muscles cells can undergo mitosis, but almost all nerve cells will not. This is true within the body and even when isolated and put into culture.

Chromosomally abnormal cells can still go through cell cycle checkpoints.
Why is a 3rd degree burn often painless?
It is often painless because it kills your nerve cells. As a result, your nerve cells can't send pain signals.
Which in DNA often occur during replication. During which phase of the cells cycle do such mutations occur?
Interphase
How does a stem cell become a nerve cell bone cell or muscle cell?
As yet, scientists are not certain how stem cells know what type of cell to become. All they can be sure of at the moment is that they respond to signals received from other, often neighbouring, cells.

How is a nerve message different from a hormone message?
Hormone messageA hormone message is a chemical, and a hormone affects target organs and a nerve message is an electrical impulse hormone travels through the blood. A hormone has long lasting effects. A hormone is secreted by a glandNerve messageA nerve message affects the receiver. A nerve message goes through a nerve and a nerve message has very short term effects. A nerve message is initiated by a response to an exterior alteration.
What kind of cell division do brain cells go through?
Dividing cells. In the embryo, most of the cells are dividing to produce more cells, this is how the embryo grows. In the adult, most cells are past their replicative lifespan (post-mitotic) and don't divide (nerve cells, muscle cells, etc.). The cells that are still undergoing cell division in the adult are stem cells or their progeny, often called transit amplifying cells (both found in many locations) involved in tissue repair, replacement or regeneration.
