Nervous System

Nervous System

Of all the body’s systems, the Nervous System is the “brains” of the outfit. It controls how all the other systems work in a huge communication network. A bit like the internet, the nervous system has messages coming in and going out every second of the day and night. It keeps track of everything going on in the body to make it run smoothly. It keeps everything in balance or in homeostasis. To do this, the nervous system’s messages have to be as fast as lightening. Like lightening, the messages throughout the nervous system are actually electrical signals. Learn about the structures and functions of the nervous system and practice using worksheets and visual aids.

NGSS Life Science Progression K-12

LS1.A Structure and Function
K-2 All organisms have external parts that they use to perform daily functions.

3-5 Organisms have both internal and external macroscopic structures that allow for growth, survival, behavior, and reproduction.

6-8 All living things are made up of cells. In organisms, cells work together to form
tissues and organs that are specialized for particular body functions.

9-12 Systems of specialized cells within organisms help perform essential functions of life. Any one system in an organism is made up of numerous parts. Feedback mechanisms maintain an organism’s internal conditions within certain limits and mediate behaviors.
