Lidocaine is what is called an open sodium channel blocker. This means that it binds preferentially to sodium channels when they are in the open (letting sodium into the cell) state.
When a motor neuron in a reflex arc is damaged, the transmission of signals from the spinal cord to the muscles is interrupted. This can result in a loss of motor function or muscle weakness in the affected area, as the muscles can no longer receive the necessary signals to contract. Consequently, reflex actions involving that motor neuron may be diminished or absent, leading to impaired reflex responses. Overall, damage to a motor neuron disrupts the normal functioning of the reflex arc.
The stimulus is detected by the sensory receptor. The sensory receptor stimulates a sensory neuron. The sensory neuron transmits to the interneuron in the spinal cord. The interneuron stimulates a motor neuron. The motor neuron communicates to the muscle. The muscle(effector) then produces the response allowing the body to respond to the stimulus.
Ether prevents the action potential, by opening potassium ion pores, which allows the escape of potassium from the neurons, which results in hyper-polarization of the neuron, thus preventing the action potential from occurring.
the neuron will be probably be inhibited from firing.
In a process called reuptake, they are reabsorbed by sending the neuron and recycled.
it prevents sodium channels from opening which removes a neuron's resting membrane potential
It depends on which area of the brain or spinal cord is affected. The functions of that area will be altered or be stopped all together.
This is what happens:a receptor detects a stimulus (change in the environment)a sensory neuron sends a signal to the relay neuronthe relay neuron sends the signal to the motor neuronthe motor neuron sends a signal to the affected partthe affected part produces a response
an action potential moves along the neuron
the myelin sheaths. The disease is classified as demyelinating , which is also known as the degeneration of the myelin structures in the neuron.
an action potential moves along the neuron
When neurotransmitters communicate an inhibitory message to the postsynaptic neuron:
The function of a neuron is to transfer messages throughout the brain. These neurons are all attached and interpret everything that happens.

Any topical neuron can be stimulated through the pressure (whether it be little or a lot) of touch. In response to a topical neuron being stimulated it can cause a chain reaction effect to the neurological mapping of the area being affected.
During an action potential, the neuron's electrical charge rapidly changes from negative to positive, allowing for the transmission of signals along the neuron.
