The autonomic nervous system (ANS) does not directly regulate the response of skeletal muscles. Skeletal muscles are controlled by the somatic nervous system, which governs voluntary movements. However, the ANS can indirectly affect skeletal muscles by regulating blood flow, oxygen delivery, and metabolic processes during physical activity, especially through the sympathetic division during "fight or flight" responses.

The autonomic nervous system (ANS) regulates the involuntary functions of visceral organs, including the heart, lungs, stomach, and intestines. It controls processes such as heart rate, digestion, respiratory rate, and blood pressure, ensuring the body maintains homeostasis. The ANS is divided into the sympathetic division, which prepares the body for "fight or flight" responses, and the parasympathetic division, which promotes "rest and digest" activities. Together, these systems work to balance organ functions based on the body's needs.

The autonomic nervous system (ANS) regulates the activity of glands, controlling their secretion levels based on the body's needs. The sympathetic division typically stimulates glands like sweat glands to increase secretion during stress, while the parasympathetic division enhances activities like saliva and digestive enzyme secretion to aid in digestion during rest. This ensures that glandular functions align with either stress responses or restful states.

The autonomic nervous system (ANS) regulates the contraction and relaxation of smooth muscles, which are found in the walls of organs like blood vessels, the digestive tract, and the respiratory system. The sympathetic division typically causes smooth muscles to contract, such as constricting blood vessels during stress, while the parasympathetic division relaxes smooth muscles, promoting functions like digestion and lowering heart rate. This helps maintain bodily functions like blood pressure, digestion, and respiration.
