Which aspect does the central nervous system NOT primarily handle?

The central nervous system (CNS) primarily consists of the brain and spinal cord, and its main functions include processing sensory information, controlling motor functions, and storing information. While the CNS does play a role in regulating certain aspects of bodily functions, digestive processes are primarily managed by the autonomic nervous system, which is considered part of the peripheral nervous system rather than the central nervous system. The autonomic nervous system specifically regulates involuntary bodily functions, such as digestion, heart rate, and respiratory rate, which are not the primary responsibilities of the CNS itself. Thus, the option indicating that the CNS does not primarily handle the regulation of digestive processes is correct.
