What makes up a neuron?

Question

What makes up a neuron?

Answer 1

we know what is black and what is white

and between these two we called it neutron

Answer 2

A neuron comprises of the following parts:

axon

dedrites

myelin sheath

transmitory cells

nucleus

cytoplasm

Answer 3

Well, aside from the standard cell structure which I believe is....

The cell body, the nucleus, and the mitochondria, it also has axons and dendrites from which it transmits neuroelectrical information and, oh, there is something you should know.

Whereas an average body cell has 1 or 2 mitochondrion, a neuron will have as many as 14.

You know all that talk in east asia regarding meditation, deep breathing, the need for fresh outside air and all that?

Yeah well turns out there is a scientific basis for it all; breathing deeply, may indeed increase brain efficiency.  Also in Daoist and Buddhist mystical traditions it is reccomended that any and all meditation is done in forested areas near trees.  Since neurons have up to 14 mitochondrion it thus makes perfect sense to retreat to a forest and meditate there.

hope that answered the question, ultimately though, pick up a neurobiology book although I'll warn, in western medical science neurobiology is a woefully underdeveloped science.  The reason accupuncture seems to be a "miracle," is because whereas western medicine is chemically based, Chinese medicine is neurobiology based, and since ultimately all things are wired to the central nervous system, what may appear as a mystery to a western doctor is a mystery because the problem may not be chemical, but neurobiological.

So how did the Chinese figure all that stuff out?  Trial and error, and crude observation, over a period of 4,000 years.  Science will give in a few decades or less, what through trial and error and crude observation would take 4,000 years.  If westerners would stop being racist, and stoped brushing off accupuncture as just primitive mumbo jumbo and actually took the time to study it, the combination of chemistry and the neurobiological knowledge of the Chinese could help save countless lives.

Medicine in east Asia, because many doctors have taken the time to scientifically study accupuncture, has actually surpassed western.

ultimately though over answer

sorry, bye

Answer 4

A neuron is a nerve cell which has three parts: dendrites, cyton, and an axon ending in axon bulb. Cyton has a nucleus and cytoplasm around it.  Axon may be covered by myelin sheath.

Answer 5

It is clear that most of what we think of as our mental life involves the activities of the nervous system, especially the brain.  This nervous system is composed of billions of cells, the most essential being the nerve cells or neurons.  There are estimated to be as many as 100 billion neurons in our nervous system!

A typical neuron has all the parts that any cell would have, and a few specialized structures that set it apart.  The main portion of the cell is called the soma or cell body.  It contains the nucleus, which in turn contains the genetic material in the form of chromosomes.

Neurons have a large number of extensions called dendrites.  They often look likes branches or spikes extending out from the cell body.  It is primarily the surfaces of the dendrites that receive chemical messages from other neurons.

One extension is different from all the others, and is called the axon.  Although in some neurons, it is hard to distinguish from the dendrites, in others it is easily distinguished by its length.  The purpose of the axon is to transmit an electro-chemical signal to other neurons, sometimes over a considerable distance.  In the neurons that make up the nerves running from the spinal cord to your toes, the axons can be as long as three feet!  

Longer axons are usually covered with a myelin sheath, a series of fatty cells which have wrapped around an axon many times.  These make the axon look like a necklace of sausage-shaped beads.  They serve a similar function as the insulation around electrical wire.

At the very end of the axon is the axon ending, which goes by a variety of names such as the bouton, the synaptic k**b, the axon foot, and so on (I do not know why no one has settled on a consistent term!).  It is there that the electro-chemical signal that has travelled the length of the axon is converted into a chemical message that travels to the next neuron.

Between the axon ending and the dendrite of the next neuron is a very tiny gap called the synapse (or synaptic gap, or synaptic cleft), which we will discuss in a little bit.  For every neuron, there are between 1000 and 10,000 synapses.

This is the best illustration I could find.
