Will the nervous system need input?

Yes, the nervous system needs input to function properly. The nervous system receives input from both the internal and external environments.

Internal input comes from the body's organs and tissues. This input includes information about the body's temperature, blood pressure, and blood glucose levels. The nervous system uses this information to maintain homeostasis, or a stable internal environment.

External input comes from the senses. This input includes information about the environment, such as light, sound, and touch. The nervous system uses this information to interact with the environment and to respond to changes in the environment.

Without input, the nervous system would not be able to function properly. It would not be able to maintain homeostasis or interact with the environment.
