When a person sees a snake and runs away immediately, in this situation his adrenaline and noradrenaline are two catecholamines that are released when the sympathetic nervous system stimulates the adrenal glands. As a result, respiration, blood pressure, and heart rate all rise.
A physiological response that takes place in the midst of anything terrible, either psychologically or physically, is referred to as the fight-or-flight response, also known as the acute stress response. The body's sympathetic nervous system is triggered by the quick release of hormones in reaction to severe stress.
What is nervous system?
Nearly all of your actions, thoughts, words, and emotions are controlled by your nerve system. It manages complex functions like memory, cognition, and movement. Additionally, it is crucial for bodily functions like breathing, blushing, and blinking that occur automatically.
Your nervous system has an impact on all facets of your health, including:
- Feelings, memories, knowledge, and experience.
- Movements involving coordination and balance.
- The interpretation of your senses by your brain, including what you can see, hear, taste, touch, and feel.
- Aging, recuperation, and sleep.
- Breathing and heartbeat rhythms.
- Response under tense circumstances.
- Digestion, along with your feelings of hunger and thirst.
- Bodily changes, like puberty.
Your body's control system is this intricate mechanism. It keeps your body's processes in check and lets you enjoy your environment.
All across your body, a large network of nerves transmit and receive electrical impulses from and to other cells, glands, and muscles. These nerves take in data from your environment. The nerves then process the data and manage your response. Your body almost feels like it has a massive information highway flowing through it.
