Human Body Muscles and Nerves: How We Keep Our Balance

How do we keep our balance? Standing without falling requires that three sensory systems work together (sight, inner ear, and proprioception). If sight isn't available, standing upright becomes more difficult. In this activity students practice standing on one leg with eyes opened and then closed. 


Questions Answered:

  • What sensory systems help keep our balance? 
  • What happens when one or more of the systems isn't working? 


Topics Addressed:

  • Three sensory systems help us keep our balance 
  • If one sensory system is compromised, the body can still remain upright 
  • If more than one sensory system is compromised maintaining balanace can be extremely difficult
