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

What is a motor neuron attached to?
A Motor neuron is a neuron that carries impulses from the spinal cord to muscle cells.A Motor neuron is a neuron that carries impulses from the spinal cord to muscle cells.
Which reflex arcs contain no association neuron?
The patellar reflex is an example of a 2-neuron reflex arc. It has 1 sensory neuron and 1 motor neuron. It does not contain an association neuron and so is considered the most simple reflex in humans.
what are the differences between pre-synaptic and post-synaptic neuron?
Yes. A synapse by definition is the space (gap) between one neurons terminal buton and another neurons dendrites. So, the neuron with the terminal buton end is known as the pre-synaptic neuron and the neuron after the synapse is known as the post-synaptic neuron.
Structure that carries messages between the brain snd other parts of the body?
The Neuron, and in this case, a motor neuron or a sensory neuron.
What neuron is before a synapse?
The synapse consists of the two neurons, one of which is sending information to the other. The sending neuron is known as the pre-synaptic neuron (i.e. before the synapse) while the receiving neuron is known as the post-synaptic neuron (i.e. after the synapse).
Where is the neuron?
The Inter-neuron (also known as the local circuit neuron, relay neuron or the association neuron) is the neuron which connects the afferent and the efferent neurons in the neural pathways.
Specialized cell that makes up the nervous system?
The cells that makes up the nervous system is the Inter-neuron (circuit neuron), sensory neuron and motor neuron.
What is a sentence with the word malfunction?
There was a technical malfunction earlier.The train malfunction caused a pile-up.
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
Define relay neuron?
a relay neuron is the neuron that picks up the message from the sensory neuron and delivers it to the motor neuron in the spinal cord or the brain
What is the function of relay neuron?
A relay neuron is the neuron that picks up the message from the sensory neuron and delivers it to the motor neuron in the spinal cord then to the brain.
What is the 3 types of neuron?
one type of neuron is the motor neuron
What is intermixed neuron?
a neuron which recieve both messages from afferent and efferent neuron...
What type of neuron connects to a muscle?
A motor or efferent neuron.
What is a neuron impulse?
it is neuron impulse
How do you spell malfunction?
The spelling "malfunction" is correct.
Is motor a neuron?
motor neuron is a type of neuron that found at the muscles, tissues, and organs.
