Sympathetic nerves: prepare the body for emergencies and stress by increasing the breathing rate, heart rate, and blood flow to muscles. These nerves become aroused as part of the fight-or-flight response, which is the body's natural reaction to real or imaginary danger.

∙ 11y agoYou have in your body, what is called as 'autonomic' nervous system. All most all body functions, where you need not give your attention but are life saving or life building are managed through this system. There is over all control of this autonomic nervous system by part in brain called as 'hypothalamus'. There are two parts of this system. 1) Parasympathetic. 2) Sympathetic. Through 'sympathetic nervous system' that fight or flightresponseis mediated.There is a chain of small nodules placed on either side of vertebral column in thorax(chest.) and abdomen attached to each other and to spinal cord. This 'thoracic-lumber' part of autonomic nervous system is called as sympathetic nervous system. It dilates the 'pupils' so that danger can be located. It increases the heart rate up to 180/minute from normal 72/minute within 5 to 10 seconds. It increases the 'stroke' volume and 'force' of contraction of heart so that cardiac out put increases from 5 liters/minutes to 25 liters/minutes. Out of which about 20/liters blood goes to muscles of body. So that the person is ready for vigorous muscle exercise needed for fight or flight response. Blood supply to skin and digestive system is reduced as it is not anemergency to supply blood to them. 'Rate' and 'depth' of respiration increases, so that more and more oxygen can be supplied to lungs and carbon bi oxide can be washed away which is toxic to the body. Oxygen is needed to produce 'energy'. Energy is needed forstrenuous exercise.Strenuousexercise is needed in this emergency situation. All 'bronchi' get dilated and theresecretionsget reduced so that oxygen and carbon bi oxide exchange should take place with easily through clear and dilated air passages. Secretions of all digestive tract get reduced including salivary glands. Also peristalsis rate is reduced on spinctures are kept closed. this is done asdigestionof food is not an emergency and it can wait for a while. Urinary bladder get relaxed and spincture is contracted. (Urination can wait a for some time.)

Which component of the nervous system calms the body after the fight-or-flight response?
The parasympathetic division of the central nervous system
The division of autonomic nervous system that controls the series of physiological responses that are collectively called the fight or flight response.?
Sympathetic division.
Which body systems does caffeine have an effect on?
Directly or indirectly, mostly sympathetic nervous system. The sympathetic nervous system is responsible for the 'flight or flight' response which was first studied by Walter Canon. The role of the sympathetic nervous system is to prepare the body for action, and in the case of caffeine, it makes you more alert, raises your blood pressure, and increases your heart rate.
Are nerves connected to the fight or flight response?
Yes, through the sympathetic nervous system. An automatic, natural response to perceived danger. Causes increase in heart rate, blood sugar level etc for immediate action.
Does the parasympathetic division of the autonomic nervous system initiate the stress response?
No..,. False
What is the hormones that are part of the body's long term response to stress?
Sympathetic Nervous System is the part of autonomic nervous system that prepares the body for action and stress.
Fight or flight NS division?
The fight-or-flight response is controlled by the sympathetic nervous system, which prepares the body for action by increasing heart rate, dilating airways, and releasing stress hormones like adrenaline. This response helps the body to either confront a threat (fight) or flee from it (flight) in order to ensure survival.
What components of the nervous system is associated with the fight or flight response?
sympathetic nervous system.
What components of the nervous system is associated with the flight or flight response?
The sympathetic nervous system originates in the spinal cord and its main function is to activate the physiological changes that occur during the fight-or-flight response.
What process does the parasympathetic nervous system not stimulate?
The parasympathetic nervous system does not stimulate the fight or flight response.
What organ and organ system is responsible for preparing the body for the Fight or Flight response during stressful situations?
The sympathetic division of the autonomic nervous system is responsible for preparing you body for the fight or flight response. The role of the hypothalamus.Combination of the brain and nervous as well as muscular and cardiovascular system. The brain initiates the process and everything becomes innate from there...the nervous system delivers the fight or flight signals, the heart beats faster and the muscles tense in order to release energy and react quicker to the organism's surroundings Adrenaline prepares your body for the fight response.
Which component of the nervous system calms the body after the fight-or-flight response?
The parasympathetic division of the central nervous system
The fight or flight response is a direct result of the activation of the...?
...sympathetic nervous system. When faced with a threat, this system triggers a series of physiological changes to prepare the body to either confront the danger or flee from it. Key components of the fight or flight response include increased heart rate, heightened senses, and the release of stress hormones like adrenaline.
What nervous system reacts to acute pain?
Response to acute pain is made by the sympathetic nervous system (the nerves responsible for the fight-or-flight response of the body).
Which system would be activated by the flight-or-flight response?
respiratory system /\ The sympathetic division of the autonomic nervous system. The sympathetic nervous system accelerates functions such as heart rate and breathing.
What commponent of the nervous system is associated with the fight or flight response?
sympathetic component.
Freezing up before speaking in front of an audience is a response to?
Parasympathetic nervous system (flight or fight response)
