Why Do You Feel Butterflies in Your Stomach

The video explores the sensation of 'butterflies in the stomach' and its connection to the autonomic nervous system (ANS). It explains how the ANS, divided into parasympathetic and sympathetic branches, controls involuntary bodily functions. The sympathetic nervous system triggers the fight or flight response, preparing the body for stress or danger. This response includes increased heart rate, dilated pupils, and redirected blood flow, influenced by hormones like adrenaline. The video also highlights the evolutionary basis for these physiological changes, emphasizing their role in survival.

What is responsible for the sensation of 'butterflies in the stomach'?

• The digestive system

• The respiratory system

• The circulatory system

Which branch of the autonomic nervous system is associated with a state of rest and digest?

• Central nervous system

• Peripheral nervous system

• Parasympathetic nervous system

What is the primary function of the sympathetic nervous system?

• To regulate sleep cycles

• To manage the fight or flight response

• To control voluntary muscle movements

• To aid in digestion

How does the body prepare for uncertainty during a fight or flight response?

• By increasing blood flow to the stomach

• By slowing down the heart rate

• By dilating airways and pupils

• By decreasing adrenaline production

What physiological change is NOT associated with the fight or flight response?
