The fastest response from the nervous system is from the autonomic system which is involuntary. Heartbeat and reflex movement come from this system which is out of your conscious control. It is centered in the cerebellum and spinal cord. Impulses from your sense organs (a bad smell or a knock to the knee) travel to your spinal cord or cerebellum -- whichever is closest to the stimulus -- and a response (coughing or knee-jerk) travels back to the area to provoke an appropriate reponse. Some voluntary responses can become involuntary responses, such as riding a bicycle. When learning how to balance, the actions are learned over and over until they become automatic. Some involuntary actions can be controlled voluntarily, such as holding your breath or a yogi who can slow his heartrate.
The amygdala and the thalamus are"hard wired" so to speak. These two regions of our brains are responsible for the fight or flight, does it eat me or do I eat it response. This is why we humans are around today. Evolution took care of the rest i.e. the mid and new brain. These regions of the brain(limbric system) allow you to respond with out needing to think about the immediate situation at hand, which of course, in modern times is not always a good thing.

The Receptor senses changes in the environment and responds by sending information to the Control Center along the Afferent.
ACH receptors can be defined as an integral membrane protein that responds to the binding of acetylcholine, a neuoyansmitter. Two example are nicotinic acetyl line receptors and muscarinic acetylcholine receptors. .

Emergency medical services are emergency services dedicated to medical care which one calls in event of serious injury or accident. The ambulance service responds to the call treating people on sight or transporting them to hospital.
The heart responds to physical activity in this way: When the human body gets pumped up(eg.excersise)the blood cells rush round your bodyto your heart then back to(if you are running)legs then back to your heart,the more blood your heart gains the healthier it becomes!>!>!>!>>!>!>!>!>!

The term 'emergency road service' is a type of service that responds to any road related accidents or problems. They work to clear all cars and debris out of one's way on the road.
In emergency outdoor care, we use the AVPU (pronounced ave poo) scale of consciousness: A - Alert V - Responds to verbal stimuli P - Responds to pain stimuli U - Unresponsive
Increased sympathetic activity causes the afferent arterioles of the renal glomerulus to constrict, thereby reducing blood flow into the glomerulus. Because a decrease in blood flow reduces blood pressure in the glomerulus, which is the driving force for filtration, GFR decreases.
Normally, the sympathetic nervous system is responds properly to the demands of the situation, however, there are some instances where it is used, but unnecessary. like job stress
During exercise, the increased muscle activity increases body temperature. The skin responds to the need to bring body temperature back into normal range in two ways. The blood vessels near the surface of the skin dilate to release extra heat, and the sweat glands make perspiration, which evaporates to lower body temperature.
