Activities such as walking, talking, and writing are regulated by the:

1. autonomic nervous system

2. central nervous system

3. involuntary nervous system

4. somatic nervous system

The correct answer is: autonomic nervous system

While all of these activities are generally controlled by the central nervous system, which includes the brain and spinal cord, the autonomic nervous system specifically regulates things like heart rate, digestion, and breathing. The central nervous system does not directly control these functions and the involuntary nervous system is not a correct term. The somatic nervous system also controls voluntary actions, but it does not regulate physiological processes like the autonomic nervous system does. Therefore, the autonomic nervous system is the most accurate and complete answer for this question.
