Many things can perturb the normal function of a neuron:

- fluid electrolyte homeostasis (sodium, calcium, potassium, chloride - all have to be tightly regulated inside and outside the cell)

- energy metabolism (Diabetes)

- temperature: cold lowers activity, heat destroys protein (meningitis kills via mechanism)

- runaway signalling from other neurons (epilepsy)

- drugs (illicit & prescribed)

- toxins (animal/plant venoms)

- pollutants/industrial chemicals

If an impulse down one neuron but failed to move on to the next neuron what is wrong with the first neuron?

It is possible that nothing is wrong with the first neuron and that the second neuron has been desensitized, or if it is the first neuron then vesicles are not fusing with the membrane and releasing neurotransmitters. This could be because a toxin has damaged the proteins that control vesicle integration, or because the calcium channels have been blocked, or in the lab setting the terminal may have run out of neurotransmitter.

Why is a neuron called an interneuron?

A neuron is called a inter-neuron because that specific neuron takes impulse from one neuron to a next neuron. For example your sensory neuron sends a impulse that you had felt a hot object. It goes through the spine to a inter-neuron to a motor neuron (this processes is called a reflex). Then the motor neuron tells your muscles in your hand to move
