The nervous system is the centre of all mental activity including all the following except ________.
- A. thinking
- B. learning
- C. digesting
- D. memory
Correct Answer: C
Rationale: The nervous system is responsible for mental activities such as thinking, learning, and memory. However, digesting is a function of the digestive system, not the nervous system. While the nervous system does regulate digestion through the autonomic nervous system, the act of digestion itself is not considered a mental activity. Therefore, digesting is the correct answer as it is not a direct function of the nervous system's mental processes.
