billions. The exact number cannot be known. We can estimate that because the nervous system makes up about 5% of the human body, and the human body contains anywhere from 10 - 100 trillion cells, that about 0.5 - 5 trillion are nerve cells.
There are many many millions of single cell neurons. It is estimated that there are up to 100 billion neurons in the human brain. It is likely that there are more neurons in the human body than any other cell type. many neurons are in the brain others are in tracts or organised pathways within the brain and spinal cord. Outside this central nervous system there are the larger most common obvious collections of individual cells that all follow the same or similar anatomic route through the body (within a single outer connective tissue pipe or sheath); for example the sciatic nerve and the radial nerve. These are the 'nerves' named and accepted by the medical community. There are three main types of nerves and, according to Wikipedia, 214 named nerves. However a biologist will soon point out there are many unnamed nerves, such as those that run to small sensors in the skin or the periosteum, and many that are repeated many more times than twice (the intercostal nerve for example). There is also a high level of personal differences in the actual neuronal anatomy of the content of named nerves so one persons sciatic nerve will not have exactly the same number neurons as the next. Neurons that commonly exit at one particular level in the spine may also in some persons exit at a higher or lower level in others. So the answer in fact must be that there are many thousands, but quite possibly millions, of bundles of smaller unnamed groups of neurons that are clearly small nerves, but medically there are the predictable larger nerves - 214 of them. It is said that there are enough neurons in the human body that if all the other cells were somehow removed the network of fine smaller nerves and neurons would be numerous enough to enable you to easily recognize the individual concerned and to recognize every tissue layer in his or her body. Finally it should also be pointed out that nerves do not supply cells or parts of the body - neurons do. Nerves are basic anatomical pathways acting as conduits within which are the real active components of information transmission - the neurons. There is perhaps just one nerve to any given muscle but this will contain perhaps a thousand neurons. each neuron branching at its end to supply thousands of muscle cells with their individual signals.
I would say there are millions or trillions or beyond. Your brain has millions or trillions, so imagine the rest of the body? I don't think there can ever be a set number.
Neurons are the nerve cells. A normal human brain has about 100 billion neurons. Nobody has told us about the number of neurons in other parts of the body. Anybody has the answer?

Most organisms contain many cells. It is estimated that the average human body has about 10 trillion nereve cells. If they were placed end to end, they would stretch around the earth about 47 times!!! A ten year old has about 5 trillion nerve cells.
There is an estimated 100 billion in the brain
There are upward of 100 billion nerve cells in the human brain.
200,000,000,000 brain Cells.

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.
The slowest dividing cells in the human body are the nerve cells. Nerve cells generate and conduct electrical impulses, allowing communication between the central nervous system and the rest of the body.
Nerve cells carry the impulses around the body to the motor neurons. Nerve impulses are received and transmitted to the cell body by axons.
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.
The longest cells are neurons (nerve cells) with a length of 90cm-100cm linking the central nervous system (brain and spinal cord) to other parts of the body.
nerve cells brings oxgygen to the body
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.
Maybe the question is not specific enough...Many kinds of nerve cells are found all over the body. The spine, the skin, the brain etc.
The slowest dividing cells in the human body are the nerve cells. Nerve cells generate and conduct electrical impulses, allowing communication between the central nervous system and the rest of the body.
The Longest cell in the human body is the nerve cell.
7 or Trillions i can never remember
Nerve Cells are capable of transmitting [relaying] bio-information.
Part of nerve cells. The axon carries the impulse toward the body of other nerve cells. Part of neurons.
they will collaped
All over your body.
