Mapping the Human Body
Learn the precise names and locations of your body's major structures, from everyday outer landmarks to subtle joints and core internal organs. Build the vocabulary you need to describe how your body moves, feels, and hurts with clarity and confidence.
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: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through Finding Your External Landmarks and Pinpointing Features and Internal Zones. It starts from scratch.

Key ideas in Mapping the Human Body
- The torso, or trunk, refers to the main central block of the body, excluding the head and limbs
- It includes the chest, back, and belly (abdomen), protecting vital organs like the heart and lungs
- Arms, legs, and the head attach to the torso rather than forming part of it
- The shoulder attaches the limb to the torso
- The upper arm sits above the elbow, and the forearm spans between the elbow and wrist
- The wrist connects the forearm directly to the hand at the outer end
- The lower limb structurally mirrors the upper limb: hip corresponds to shoulder as the ball anchor
- The hinge joint in the middle of the arm (elbow) mirrors the hinge in the leg (knee)
- The transition joint (wrist) mirrors the ankle, leading to the terminal contact point (hand to foot)
- Bilateral symmetry means the left and right halves of the outside of the body form approximate mirror images across a vertical midline
- Limbs, eyes, ears, and cheeks come in mirrored pairs on opposite sides
- Central features like the nose, mouth, and navel (belly button) lie directly on the line of symmetry
- The collarbone (clavicle) runs horizontally across the front of the upper chest to connect the breastbone to the shoulder
- The shoulder blade (scapula) floats against the back of the ribcage, moving whenever the arm reaches or lifts
- Together, the collarbone and shoulder blade form the mobile frame that anchors the entire arm to the ribcage
- The elbow bends and straightens the arm between the upper arm and forearm
