Which of the following is NOT a function of the nervous system?

1. Controlling movement

2. Regulating emotions

3. Digestion of food

4. Receiving sensory information

The correct answer is: Digestion of food

The function of the nervous system encompasses various roles such as controlling movement, regulating emotions, and receiving sensory information. It is primarily responsible for sending and receiving signals throughout the body that allow communication between the brain and different parts of the body. Digestion of food is primarily managed by the digestive system, which includes organs such as the stomach and intestines. While the nervous system does play a role in overseeing the digestive process by sending signals to the digestive organs to function properly, it does not directly manage the digestion itself. Therefore, understanding that the primary function of the nervous system is related to signaling and communication helps clarify why the act of digestion falls outside the direct responsibilities of the nervous system.
