Human Anatomy: Built to Move
Discover the mechanical genius beneath your skin. Learn how your bones, muscles, lungs, and heart coordinate to move you through the world.
Like Duolingo, but for Human Anatomy: Built to Move. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through The Mechanical Frame and The Pressure Systems. It starts from scratch.

Key ideas in Human Anatomy: Built to Move
- Limb bones act as levers that pivot around joints acting as fulcrums
- Muscles attach close to the pivot, requiring large effort forces to lift small weights
- This mechanical setup allows the hand or foot to move much faster and sweep through a wide arc with small muscle contractions
- Ball-and-socket joints allow wide, multi-directional motion but risk dislocation
- Hinge joints lock motion to a single back-and-forth plane, providing strong structural support
- The shoulder socket is shallow for maximum reach, whereas the hip socket is deep for bearing body weight
- Bone ends are capped with smooth cartilage that absorbs shock and prevents bone grinding
- Joint cavities contain slippery synovial fluid that acts as an oil slick between moving parts
- Direct bone-on-bone contact causes severe wear, grinding, and pain
- Ligaments anchor bone directly to bone across a joint
- Ligaments act like tough, non-stretchy straps rather than elastic rubber bands
- Their job is to physically check movement and stop joints from twisting or hyperextending beyond safe limits
- Bone is living tissue that constantly absorbs and deposits mineral density
- High-impact or weight-bearing activities prompt bones to lay down denser structure where the strain occurs
- Lack of mechanical load, such as prolonged bed rest or spaceflight, causes bone mineral loss
- Muscles can only pull by contracting; they cannot actively push bones apart
