What is the main difference between the parasympathetic and sympathetic divisions of the autonomic nervous system?
What is the main difference between the parasympathetic and sympathetic divisions of the autonomic nervous system?
- The parasympathetic division is responsible for the physiological distribution of the body, while the sympathetic division is involved in the anatomical distribution.
- The parasympathetic division controls voluntary movements, while the sympathetic division controls involuntary functions.
- The parasympathetic division controls smooth muscles, while the sympathetic division controls skeletal muscles.
- The parasympathetic division is active during times of stress, while the sympathetic division is active during rest and digestion. (correct)
