Verified step by step guidance

1. Understand the autonomic nervous system (ANS): The ANS is a part of the peripheral nervous system that controls involuntary physiological functions, such as heart rate, digestion, and respiratory rate. It is divided into the sympathetic, parasympathetic, and enteric divisions.
2. Learn the role of the sympathetic division: The sympathetic division is responsible for preparing the body to respond to stress or danger. This is commonly referred to as the 'fight or flight' response. It increases heart rate, dilates airways, and redirects blood flow to muscles, among other effects.
3. Contrast the parasympathetic division: The parasympathetic division is often referred to as the 'rest and digest' system. It promotes relaxation and recovery by slowing the heart rate, stimulating digestion, and conserving energy.
4. Understand the enteric division: The enteric division is a network of neurons that governs the function of the gastrointestinal system. It operates independently of the sympathetic and parasympathetic divisions but can be influenced by them.
5. Recognize the somatic division: The somatic division is not part of the autonomic nervous system. It controls voluntary movements of skeletal muscles and is not involved in the 'fight or flight' response.
