What would happen to part of an axon if it is cut so that it is no longer connected to its nerve cell?

there wouldn't be an impulse
. This can be seen in the injury of the breaking of the backbone/cutting of the spinal cord
. The grey matter of the spinal cord is composed of motor neuron
and accessory (?) neuron axons, and when these are cut, the impulses cannot be transmitted to the dendrites of the next neuron, or for that matter the effector. This results in paralysis from the site of injury down.

∙ 10y agoAn axon is dependent upon its parent neuronal cell body. The axoplasm does not contain ribosomes, which means axons cannot produce proteins. Axons also have limited lysosomal capacity, meaning waste products need to be returned to the parent cell body for degradation.
This means that if an axon loses connection with the neuronal cell body, it will die.

Which cranial nerve is used in reading the paper?
The main nerve required would be the optic nerve (II), although you would also use the ocular motor nerve (III) to move the eyes. Other cranial nerves involved are: Trochlear nerve (IV) and Abducens nerve (VI).
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.
Suppose a portion of an axon is cut so that it is no longer connected to its nerve cell body. what effect would that have on transmission of impulses?
you can have a disease of that adnormality event in your Nervous system

Would there be a loss of sensory or motor function when someone damages the dorsal root of a spinal nerve?
Yes this can happen when any nerve is damaged but this is a greater danger if its an actual Spinal Nerve.
What would happen if the ventral root of a spinal nerve were damage or transected?
There are a number of things that would happen if the ventral root of a spinal nerve were damage or transected, This would mainly cause the loss of the sensory function and there would be neuropathic pain among other effects.
What would happen if you damaged cranial nerve one?
