Question

What happens in the nervous system when a person becomes paralyzed?

Answer 1

It depends on the etiology of the paralysis.

For instance, some toxins can paralyze you through antagonism with `"AChR"`. These receptors exist at the neuromuscular junction in the postsynaptic density and "listen" to motor neurons from the spinal cord.

Moreover, direct damage to motor neurons in the spinal cord can lead to paraplegia.

To be sure, the pathology involves a disruption in communication at the neuromuscular junction, to avoid giving you a headache.
