How do non functional sodium channels affect the signaling capabilities of neurons?

When sodium enters the neuron, it depolarizes it. This means that the neuron becomes more positive. This can lead to the neuron reaching threshold and then initiate an action potential.
When the sodium channels are NOT functional, the sodium can not enter and depolarize it. Therefore the threshold can not be met and action potential will not occur.
If the sodium channels are inactive in an nociceptive neruon (carries information about pain), then the it will prevent you from feeling pain.

How will preventing the inactivation of sodium channels affect the signaling capability of a neuron?
When sodium channels are not active, it means that the capability of neurons to send the electronic signals in the body weakens. Neurons are nerve cells that communicate by passing Na+ and K+ ions.
Which of the following is NOT a functional classification of neurons?
Extraneurons
Which is not a functional classification of neurons?
Extraneurons
What is the functional component of the nervous system?
Neurons.
Are neurons in the CNS organized into functional groups?
Yes.
What type of channels that are present within the varicosities of autonomic neurons are absent from the axon terminal of other neurons?
Voltage-gated Sodium ions and Potassium ions channels
What effects does TTX have on neurons?
It blocks the voltage-gated Na+ channels.
What plays a critical role as a functional junction between neurons?
SYNAPSE
Is the nerve the functional unit of the nervous system?
No. The functional unit of the nervous system is the neuron. Neurons group together to form nerves.
Functional difference between a motor and a relay neuron?
Motor neurons are the efferent neuron which carry impulses from CNS to muscles while relay neurons also known as Inter neurons connect both afferent and efferent neurons.
What functional advantages a neuron with several have over a neuron with only one dendrite?
These are also called multipolar neurons and they allow for the integration of a great deal of information from other neurons.
What changes occur in the neuron?
Neurons undergo depolarization and repolarization when stimulated. The sodium and potassium channels open.
