Detailed explanation-1: -The autonomic nervous system comprises two parts-the sympathetic and parasympathetic nervous systems. The sympathetic nervous system activates the fight or flight response during a threat or perceived danger, and the parasympathetic nervous system restores the body to a state of calm.
Detailed explanation-2: -The sympathetic division initiates the fight-or-flight response and the parasympathetic initiates the rest-and-digest or feed-and-breed responses. The sympathetic and parasympathetic nervous systems are important for modulating many vital functions, including respiration and cardiac contractility.
Detailed explanation-3: -The sympathetic and parasympathetic divisions of the nervous system are both autonomic. Though they innervate some skeletal muscles, they also play keys roles in other bodily functions, such as heart rate and blood pressure regulation. The somatic nervous system is the only division to only innervate skeletal muscle.
