Hello students, sympathetic nervous system is concerned with protective responses at the time of emergency.

For example, in presence of danger, the sympathetic nervous system leads to the forward dilation of nostrils, increase in rate of breathing, stoppage of peristaltic movements, closure of sphincter, erection of hair, constriction of peripheral blood vessels etc.

Thus, sympathetic nervous system prepares our body for a fight or flight response during the time of emergency.

This increases the defense system of body against stress, fear, pain, anger etc.

On the other side, parasympathetic nervous system is usually called the housekeeper system because it promotes all internal responses with relaxed state.

Parasympathetic nervous system counteracts the effects of sympathetic nervous system and it tends to restore normalcy...
