Mapping the Human Body, a free science course on Tomo

Mapping the Human Body

Learn to read your own physical structure using accessible bony landmarks and mechanical principles. Understand how bones, muscles, internal cavities, and vital vessels fit together into a coordinated architectural system.

Like Duolingo, but for Mapping the Human Body. 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 Skeletomuscular Framework and The Internal Architecture. It starts from scratch.

What you'll learn

Key ideas in Mapping the Human Body

  • The anatomical position serves as a constant universal map, standing upright with palms facing forward
  • Directional terms like superior (toward the head) always describe the body's internal reference map, regardless of the patient's actual posture or movement
  • Superior does not mean 'toward the sky' or 'upward relative to the room'
  • Fat and muscle shift, change size with posture, or differ widely between people
  • Bones close to the skin provide rigid, unmoving reference points that stay consistent across different body types
  • The axial skeleton comprises the central core (skull, spine, ribs) built primarily to protect delicate organs like the brain, heart, and spinal cord
  • The appendicular skeleton includes the limbs and the girdles attaching them, optimized for locomotion, reach, and manipulation
  • The central pillar prioritizes stability and defense, while the outer limbs prioritize range of motion
  • The outside of the body has paired limbs and features mirrored across the midline
  • Single organs like the liver (mostly right side) and the spleen and stomach (mostly left side) break this symmetry inside
  • Lungs and kidneys are paired organs that occupy both left and right sides
  • Internal organs sit behind or align with specific surface bones that can be felt through the skin
  • Palpating the bony borders (like the ribs or pelvic rim) reveals where deeper organs begin and end without needing medical imaging
  • Surface skin contours alone are unreliable because soft tissues shift
  • Muscle fibers can only shorten toward their center and pull on bones
  • Muscles have no mechanical way to lengthen under their own power to push a bone away
