Musculoskeletal Anatomy: How Your Body Moves, a free science course on Tomo

Musculoskeletal Anatomy: How Your Body Moves

Decode the bones, joints, and muscles that power every step, lift, and reach. Learn to trace anatomical landmarks on your own body and see how paired muscles act as living levers and pulleys.

Like Duolingo, but for Musculoskeletal Anatomy: How Your Body Moves. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through Mapping the Upper Chassis and The Lower Body Engine. It starts from scratch.

Key ideas in Musculoskeletal Anatomy: How Your Body Moves

  • Bony landmarks are hard skeletal edges or bumps that sit directly under the skin without thick muscle covering them
  • Soft, squishy tissues like muscle bellies or fat pads are not bony landmarks
  • Palpable landmarks like the elbow tip (olecranon), kneecap (patella), and hip crest give surface roadmaps for where muscle bellies begin and end
  • Hinge joints (like the elbow or knee) restrict motion strictly along one plane, gaining stability from tight interlocking bone shapes
  • Ball-and-socket joints (like the shoulder or hip) allow multi-directional rotation across multiple planes
  • Ball-and-socket joints gain freedom of motion by sacrificing the tight bony interlocking that stabilizes hinge joints
  • Tendons connect muscle tissue to bone, acting as durable cables that transfer muscle contraction into skeletal movement
  • Ligaments connect bone to bone across a joint, acting like tough straps that prevent bones from pulling apart or dislocating
  • Muscles pull through tendons; ligaments do not contract to generate pulling force
  • The collarbone (clavicle) is the only bony strut connecting the entire arm and shoulder assembly to the central skeleton at the breastbone
  • The shoulder blade (scapula) does not form a true bony joint with the ribs; it floats across the rib cage suspended and guided purely by layers of muscle
  • This floating muscular design allows the shoulder blade enormous freedom to glide, tilt, and rotate around the torso
  • Muscle fibers can only actively shorten and pull; they cannot push
  • Straightening a bent joint requires an opposing muscle on the other side (like the triceps) to contract and pull in the opposite direction
  • The pectorals attach across the chest and pull the upper arm forward and inward (like in a hug or push-up)
  • The latissimus dorsi spans the back and pulls the upper arm downward and backward (like in a pull-up or row)
