    List 3 physical activities in which the human body engages in movement.Next:Determine which bones are involved in these movements.

  • Science -

    It depends on how you define physical activities. It could range from running to typing to weight lifting or chewing gum. Depending on the activity, all bones could be involved in the movements.

    Since this is not my area of expertise, I searched Google under the key words "bone movement" to get these possible sources:

    http://www.kidshealth.org/teen/your_body/body_basics/bones_muscles_joints.html
    http://vudat.msu.edu/bone_movement/

    In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

    I hope this helps. Thanks for asking.

    Additionally, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where is more likely to be overlooked.

    I hope this helps a little more.
