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 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).
What is a presynaptic neuron?
a neuron from the axon terminal of which an electrical impulse is transmitted across a synaptic cleft to the cell body or one or more dendrites of a postsynaptic neuron by the release of a chemical neurotransmitter.
What is the first motor neuron in an autonomic pathway called?
The first motor neuron in an autonomic pathway is called a preganglionic neuron. It originates in the central nervous system and synapses with a postganglionic neuron in an autonomic ganglion.
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.
What happens when a substance gets into a neuron?
When a substance enters a neuron, it can bind to receptor sites on the neuron's membrane, triggering a cascade of events within the neuron. This can lead to changes in the neuron's electrical activity, release of neurotransmitters, or alterations in gene expression, ultimately affecting the neuron's function.
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.
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.
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 3 types of neuron?
one type of neuron is the motor neuron
What type of neuron connects to a muscle?
A motor or efferent neuron.
What is intermixed neuron?
a neuron which recieve both messages from afferent and efferent neuron...
What is a neuron impulse?
it is neuron impulse
What is a sentence with the word malfunction?
There was a technical malfunction earlier.The train malfunction caused a pile-up.
What is another name for afferent neuron?
sensory neuron or receptor neuron.
Is motor a neuron?
motor neuron is a type of neuron that found at the muscles, tissues, and organs.
A name for a nerve cell is?
A neuron.
