How does the nervous system and endocrine system communicate?
The endocrine system acts as a communication tool within the human body, working in tandem with the nervous system to communicate with the body’s other internal systems. Both the nervous and endocrine systems send messages everywhere inside the human body.
How does the nervous system and endocrine system work together to control heart rate?
The sympathetic nervous system (SNS) releases the hormones (catecholamines – epinephrine and norepinephrine) to accelerate the heart rate. The parasympathetic nervous system (PNS) releases the hormone acetylcholine to slow the heart rate.
How are the functions of the endocrine system and nervous system similar?
It’s similar to the nervous system in that it plays a vital role in controlling and regulating many of the body’s functions. However, while the nervous system uses nerve impulses and neurotransmitters for communication, the endocrine system uses chemical messengers called hormones.
Is the fight or flight response parasympathetic?
Your sympathetic nervous system is responsible for how your body reacts to danger and is responsible for the fight or flight response. While your parasympathetic nervous system is responsible for maintaining homeostasis, which is your body’s built-in stability monitor.
What is the fight or flight response called?

What happens in the brain during fight-or-flight?
During a fight-flight-freeze response, many physiological changes occur. The reaction begins in your amygdala, the part of your brain responsible for perceived fear. The amygdala responds by sending signals to the hypothalamus, which stimulates the autonomic nervous system (ANS).
What are three effects stress has on our bodies?

The body begins to tire, the immune system declines, and as we have learned in recent research, the brain can even begin to become toxic. Until the bone is returned to its proper position, and range of motion the body is likely to be stuck in fight or flight.
Does fight-or-flight make you stronger?
And while the adrenaline fueled fight-or-flight reflex spurs people into action, the body’s entire stress response contributes to superhuman strength. Cascades of enzymes and proteins release, helping people sustain the activity.
