Central nervous system
Somatic nervous system
Sympathetic nervous system
2. Which of the following hormones is NOT primarily involved in the immediate 'fight or flight' response?
Adrenaline (Epinephrine)
Noradrenaline (Norepinephrine)
Cortisol
Insulin
1. The nervous system is responsible for the 'rest and digest' functions, counteracting the effects of the fight or flight response.
2. During a fight or flight response, blood is redirected from the digestive system to the .
3. The primary gland that releases adrenaline and noradrenaline into the bloodstream is the gland.
1. Describe two physiological changes that occur in the human body during the 'fight or flight' response and explain their adaptive purpose.
2. Explain the role of the amygdala in initiating the 'fight or flight' response.
