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 systemcamera 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.
