The cells work together to allow very quick response to threats of any kind. For example if it heat threat, heat receptors will detect the stimuli and send information to the inter neuron. From the central nervous system a motor neuron will send a response to the skeletal muscle in the harm causing the harm to contract and pull out of danger. the fundamental process of neuron transmission that underlies this this action occurs in all neurons of the body. Neurons transmit this information through changes in the electrical potential of the membrane by the movement of ions across the membrane.That how the mechanism of transmission of an impulse along neuron works.
I trust this resource because it is reliable and it has clearly explained the mechanism of transmission of an impulse along neuron which is

I trust this source because it explains the role of sensory and motor neurons in a reflex arc. This is a reliable source because the information is understandable and clear.

Voluntary actions are actions in which the person initiate by their own conscious like walking or running and reflex actions are involuntary actions they are total opposite of voluntary actions. In voluntary action the cerebral cortex(brain) sends impulses from it to the effectors(muscles or glands) via the spinal cord with the relay neurons and finally a motor neurons. This action is under the control of the will. When in reflex actions the spinal cord takes control of the will for example blinking, coughing, and sneezing. This what differentiate the two actions one the person is conscious of what they are about to do or doing while the other the body just do it with or without the person thinking about it.

I trust this resource because it has clearly explained the different between the two actions. Now I have a better understanding of the different between reflex and voluntary action.

It works automatically without a person's conscious. In autonomic nervous system many organs are controlled primarily by either the sympathetic or parasympathetic division. Sometimes the two divisions have opposite effects on the same organ. For example the sympathetic division increases blood pressure and the parasympathetic division decreases it. Overal the two divisions work together to ensure that the body responds appropiately to different situations that occurs within the body.

Sympathetic division prepares the body for stressfull or emergency situations. Fight or flight. It does increase the heart rate and the force of the heart consantractions and widen airways to make breathing easy when someone is running out of danger.
Parasympathetic division controls body process during ordinary situations such as eating or just relaxing or doing anything usual. Generally it conserves and restores
