Final answer:
The autonomic nervous system consists of the sympathetic and parasympathetic divisions, with an additional enteric division playing a role in gastrointestinal function. The sympathetic is for fight-or-flight responses, while the parasympathetic is for rest-and-digest activities. Option number 1 is correct.
Step-by-step explanation:
The divisions of the autonomic nervous system are as follows: the sympathetic division and the parasympathetic division. An additional division, the enteric system, is sometimes considered a third division due to its significant role in gastrointestinal functioning; thus, the correct answer to the student's question is option 4) Sympathetic, parasympathetic, enteric.
The sympathetic division prepares the body for stress-related activities and is often referred to as the fight-or-flight response, while the parasympathetic division takes control during restful periods aiming to conserve energy and is associated with the rest-and-digest or feed-and-breed activities. Unlike the autonomic nervous system which regulates involuntary bodily functions, the somatic nervous system provides control over skeletal muscles and mediates voluntary movements such as turning a steering wheel.
