Key ideas in The Body in Motion
- Muscles can only generate force by contracting and shortening
- Straightening a limb requires a different muscle to pull from the opposite side
- Opposing muscles must coordinate so one relaxes while the other pulls
- The pivot point allows the pulling force to create a rotation
- Why muscles cannot push bones
- The relationship between partner muscles during movement
- Muscles attach near the joint to turn small tugs into wide arcs
- Bones act as levers that trade force for a greater range of motion
- The main muscle must shorten to create the initial pull
- The partner muscle must yield to allow the bone to move
- The bone rotates around the joint like a swinging door
- How bones act as levers to amplify movement
- The sequence of events in a simple limb movement
- Any joint that moves back and forth needs two sets of pullers
- A single muscle cannot return a bone to its original position
- Identifying the necessity of muscle pairs
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives The Body in Motion the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
