Topic Overview
The
nervous system is a complex, highly specialized network. It organizes,
explains, and directs interactions between you and the world around you. The
nervous system
controls:
- Sight, hearing, taste, smell, and feeling (sensation).
- Voluntary and involuntary functions, such as movement, balance, and coordination. The nervous system also regulates the actions of most other body systems, such as blood flow and blood pressure.
- The ability to think and reason. The nervous system allows you to be conscious and have thoughts, memories, and language.
