You are in the forest and see a large, snarling, drooling grizzly bear running directly toward you. The adrenaline rush you feel as you run toward the cabin is controlled by the sympathetic nervous system.
The sympathetic nervous system is a part of the autonomic nervous system which functions through various interconnected neurons. The sympathetic nervous system’s main role is to stimulate the neuronal and hormonal stress response (also known as body's fight-or-flight response). The sympathetic fibers in the adrenal medulla (inner part of the adrenal gland) produce acetylcholine (a neurotransmitter), which allow the high secretion of adrenaline and low amounts of noradrenaline from it. The sympathetic nervous system also prepares the body for action, especially in situations that are dangerous to survival.

Gulliver
was a surgeon and he was on the ship named “Antelope”. When a violent storm
came and the ship sank, all the crew members were engulfed in the ocean. Gulliver
somehow managed and swam to the shore.
He
was so tired that soon he fell into a deep sleep and when he woke he saw that
he was caught and chained by little men called Lilliputians who lived there.
At
first, when he tried to free himself, they were frightened of him and fire
dozens of arrows in to his chest, hands, and arms but later they treated him
very well. Gulliver admitted that first he want that take people in his hand
and crush them but when they treated him well, he also treated them well. He was
impressed by their nice hospitality they showed.

The energy needed by a system to initiate a process is called as the activation energy. It describes the minimum energy which must be available to a chemical system with potential reactants to result in a chemical reaction. Hope this answers the question.
