It presupposes an active interposition of the glia cells between the axon of one neuron and the dendrons of another.
Even though the peripheral neuron may be suffering to some extent, this is true.
If what we might call, to borrow a figure from electricity, the voltage of the cell impulse be sufficient to overcome the resistance at the synapse, the impulse passes from neuron to neuron.
These are transferred from neuron to neuron through the synapse.
Ailments of this kind, which involve inability of the will to control, or rather to initiate, movements of the body, receive their best explanation on the neuron or neuroglia theory.
That is not a loss of memory but a failure of neuron connections.
The peripheral neuron for sensation runs from the surface of the body to the spinal cord, while for motion it runs in the opposite direction.
Each neuron does not extend to and from the brain and the periphery, but series of neurons connect the surface of the body with the brain.
In this respect, the neurondoes not differ essentially from the cell of a muscle.
On account of this property, an excitation, or disturbance, in any part of a neuron is conducted or carried to all the other parts.
This movement through the neuron is called the nervous impulse.
An impulse started by the external stimulus goes only so far as its neuron extends.
Just as the muscle cell requires a stimulus to make it contract, so does the neuron require a stimulus to start the impulse.
Conductivity is the property which enables the effect of a stimulus to be transferred from one part of a neuron to another.
The same impulse does not pass from one neuronto another.
For example, a single neuron passing out from the spinal cord may, by terminating in a sympathetic ganglion, stimulate a large number of neurons, each of which will in turn stimulate the cells of muscles or of glands.

Proof of this is found in the fact that when any part of the neuron is separated from the cell-body, it dies, while the cell-body and the parts attached to the cell-body may continue to live.
A developed neuron consists of a cell body with numerous prolongations in the form of white, thread-like fibres.
The neuron with its outgoing fibres is the unit of the nervous system.
Thus the nervous impulse passes from one neuron to the other at these points of contact.
The axon of each neuron ends in an elaborate series of fine branchings which lie in contact with the dendrites of another neuron, or in some cases with the body of the other cell (Fig.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "neuron" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: brain; ganglion; nerve; neuron; plexus; synapse
