It depends on the tissue. Most nerves are too small to see individually, but there are bundles that can be viewed with the naked eye or a good dissecting microscope. Nerves can be myelinated, which means that they coated with a fatty layer to speed signal transmission. Most peripheral nerves and those not in the cortex of the brain are myelinated and thus appear white. Unmyelinated nerves are grayish, which is where the term "gray matter" comes from.

How can you use nerve cells in a sentence?
Nerve cells are a part of the nervous system. There are nerve cells all around the body. Without nerve cells your body would not function the way it does.

How can you use the word mitosis in a sentence?
Mitosis is used as a noun in sentences. Nerve cells rarely undergo mitosis.
How do you culture nerve cells?
Each type of cell has its own special requirements in terms of exact pH, nutrients, and growth factors. And, nerve cells require such specific requirements that there is no one sure way to culture them. The general process is to isolate the tissue through surgery, and then use mechanical plus enzymatic disassociation of the tissue, light centrifugation, and rinsing in media to remove enzymes then initial plating. This is actually very difficult to do in practice. Another obstacle is that primary nerve cultures (taken directly from living tissue) have a relatively short lifespan. Nerve cells are not like skin cells in that they generally lack the ability to replicate.
These cells use mitosis to divide into two daughter cells?
Both plant and animal cells use mitosis to form two daughter cells. They are usually called soma (body) cells but there are some exceptions: nerve cells and liver cells. The liver cells can divide in the time of need.

How are human smooth muscle cells similar to human nerve cells?
All muscle cells and nerve cells use an action potential and also obey the all-or-none law
Does the synapse occur between nerve cells?
I wouldn't use the word "occur" since a synapse is a structure, not an event, but yes, it is located between nerve cells, or more specifically, it is where the dendrites of two nerve cells meet.

how do nerve cells and muscle cells work?
Nerve cells and muscle cells are excitable. Their cell membrane can produce electrochemical impulses and conduct them along the membrane. In muscle cells, this electric phenomenon is also associated with the contraction of the cell. Thank you, regards (me).
How do you use the word nerve in a sentence?
You didn't say which meaning of the word you wanted to use. Nerve can mean a part of the body. Nerve pain can be a symptom of diabetes. The brain is made of many nerve cells. Nerve can also mean courage. He had the nerve to face the giant when nobody else would. You can also use nerve as a slang. "To get on one's nerves" means to bother or annoy one. "You are getting on my last nerve," Mom warned.
What cells let use sense pain?
A person senses pain, pressure, cold, hot by using nerve cells under the skin.
What job do a nerve cell?
Nerve Cells: A. Use systems of cells in certain senses for example, eyes to receive messages. B. Receive touch messages C. Transmit those messages to other nerve cells D. Eventually, through passing the message from nerve cell to nerve cell the message is either transmitted to the brain for longer thought or to the spinal cord for a quick reflexive reaction. E. Do this all insanely fast.
Should stem cells be used to treat neurological disorders?
Nerve cells are terminally differentiated. This means that they are incapable of dividing and forming new nerve cells. An adult has a fixed number of nerve cells. During certain disease conditions, these nerve cells become degraded or non-functional. The non-functional cells cannot be replaced by new ones through any natural process. Therefore, the use of stem cells for the treatment of neurological disorders has been investigated in recent years. Since stem cells are not terminally differentiated, they can be treated to generate nerve cells. Symptoms of neurological diseases could be mitigated through cell replacement therapy. Should stem cells be used? yes. Is it going to work? Maybe. This area is being researched actively.

How was colored photography important?
The most important aspect of colored photography was the cure for the Polio virus. In order for scientists to distinguish the difference between cells in a sample, they needed to use high resolution photographs. When the photos were taken, all the cells appeared in black & white, so scientists could not distinguish between the gamma cells and the beta cells. Gama cells are dark red in color and beta cells are dark blue. When the first color camera was used to document these microscopic cells, Dr. Francis Wellington was able to extract the gamma cells to use in creation of the vaccine.
How would you distinguish between the light microscope and the electron microscope?
Light microscopes can use live cells and are much smaller than electron microscopes
