The brain and spinal cord make up the fight-or-flight response.

Answer 1

This response is a complex physiological reaction that helps the body prepare to either fight or flee in the face of a perceived threat or danger. When the brain perceives a threat, such as a dangerous situation or a stressful event, it sends signals through the spinal cord to various parts of the body to initiate a series of changes. This can include increased heart rate, rapid breathing, dilated pupils, and the release of stress hormones such as adrenaline and cortisol.

These changes help the body to react quickly and effectively in a potentially dangerous situation. The fight-or-flight response is an important survival mechanism that has evolved over time to help humans and animals respond to threats and protect themselves from harm.
