Matt is sitting in a chair at a table anxiously waiting for his pizza to arrive. The doorbell rings and Matt moves from his chair to go to the door to meet the pizza delivery guy. In the process of moving from his chair to ultimately sitting back in his chair and eating his pizza he has to progress through a series of motions. First he must stand upright from his sitting position in the chair. He turns around 180 degrees to face the door. Then he takes several steps forward, grabs the door knob, turns it 180 degrees clockwise and pulls open the door. Once he has the pizza in hand, he turns back around, walks back to his chair and sits down. He places a piece of pizza on plates for both he and Maria. He grasps his slice of pizza, raises it to his mouth, takes a bite, which he then chews and swallow s.
All the actions that Matt made to move from the chair to the door and back to the table involved the contraction of voluntary skeletal muscles that are each innervated by a specific nerve and each of which cross a specific joint or set of joints to produce a specific action. The series of above actions took Matt less than 3 minutes to complete.
