The short pathway that carries the impulse for an automatic response is called a reflex arc.
the neuron pathway
Extrapyramidal pathway
Nerve pathways are slim, however neurones are small in size therefore the total amount of atoms in the impulse is enough to fit through a gap in the pathway of neurons

It is heat transfer by the collision of atoms within our atmosphere.

During a pain withdrawal reflex impulses are sent through different nerves and to the spinal cord. This reflex does not make it to the brain but only to the spinal cord. We call this involuntary action because we dont control reflexes. The sensory neurons are the first to recieve the impulse, then they travel to the interneurons, or associative neurons, and then they go to the motor neurons which carries the impulse to the central nervous system. Then the effector is the response, so in this case your musscle will contract.
A reflex is an automatic response, that protects the organism from a harmful stimulus. The receptors detect a stimulus which generates a nerve impulse along the sensory neurone to the Central Nervous System (CNS). The CNS decides the appropiate response to the stimulus. The nerve impulse then travels across a synapse to the relay neurone, across another synapse to the motor neurone to the effector. This is normally a muscle or an organ which moves or responds to bring about a response appropiate to the stimulus.

The classical complement pathway is a group of proteins that arrange the antibody response when you are sick. So basically they will spring into action when something is not right in your body.
