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.
Pupils dilate in the fight or flight response to allow more light to enter the eyes, helping to improve vision and awareness in dangerous situations.
The fight or flight hormone, also known as adrenaline, is produced by the adrenal glands in response to stress or danger. It triggers the body's physiological response to prepare for a physical challenge or to flee from a threat.
When faced with a situation your body has two natural responses. Fight, or Flight. If your body does not tell you to run away (or fly) then you have chosen the Fight response. The response can be triggered by man things including emotions for the day, and the balance of chemicals in your body at the time.
The main hormone released during the flight or fight response is adrenaline, also known as epinephrine. This hormone is produced by the adrenal glands in response to stress or danger, preparing the body to react quickly in a threatening situation.
In a stressful situation, the fight or flight response triggers the release of adrenaline, which causes the pupils to dilate. This allows more light to enter the eyes, helping to improve vision and awareness in order to better respond to the perceived threat.
Response to acute pain is made by the sympathetic nervous system (the nerves responsible for the fight-or-flight response of the body).
Nerves that release nor-epinephrine are classified as noradrenergic nerves. Noradrenergic nerves are part of the sympathetic nervous system and play a role in the body's fight-or-flight response.
I don't think there is because fight or flight is response action the body makes when in a dangerous situation. Stand and fight or flight RUN.
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.
The ALARM response
The fight or flight response is triggered by the release of stress hormones like adrenaline and cortisol in response to a perceived threat or danger. This response prepares the body to either confront the threat (fight) or escape from it (flight) in order to ensure survival.
The adrenal medulla is responsible for the fight-or-flight response. It releases a hormonal cascade that results in the secretion of epinephrine and nonrepinephrine.
Walter Cannon, a harvard physiologist, first investigated the fight or flight response in 1927.
