The Human Body, Head to Toe

Learn the body the way you actually look at a person: from the top down. This track names every part in order — starting at the skull, then the face and its sense organs, down the neck to the chest and belly, out along the arms and hands, and finally down the legs to the feet. Each lesson is one clear figure you label yourself, and the label on every connection tells you what that part is for, not just what it is called. Nothing is memorised out of context: because the order follows the body, each part arrives where you would meet it if you were looking someone over from head to toe. By the end you can point to any part, name it, and say what job it does.

One skull, many bones — label the cranium, sockets, cheekbones and jaws, and see why only one of them can move
Beginner 8 min Part 1

What Are the Main Bones of the Skull?

The skull looks like a single bone, but it is really about twenty-two locked together — with just one left free to move. Learn what each main part does, then label a skull yourself in an interactive playground.

One backbone, five regions — label the spine from the neck to the tailbone and see what each stretch is built to do
Beginner 8 min Part 2

What Are the Main Parts of the Spine?

The spine looks like one bony rod, but it is about thirty-three bones in five regions, each shaped for a different job. Learn the regions of the backbone, then label them yourself in an interactive playground.

Bone, cartilage, and three kinds of rib — label the chest and see how a cage can be both a shield and a bellows
Beginner 8 min Part 3

What Are the Parts of the Rib Cage?

The rib cage has to do two opposite jobs: guard the heart and lungs like armour, yet move with every breath. Learn its parts — the breastbone, the springy cartilage, and the true, false and floating ribs — then label them yourself in an interactive playground.

One bone up top, two below — label the arm and see why that split is what lets you both lift and twist
Beginner 8 min Part 4

What Are the Bones of the Arm?

The arm is built from one thick bone in the upper arm and two slimmer bones in the forearm, meeting at a hinge. Learn what each bone does — and why the two-bone forearm is what lets you turn your palm — then label them yourself in an interactive playground.

One hip bone, three bones in disguise — label the pelvis and see where you sit, and where your leg plugs in
Beginner 8 min Part 5

What Are the Parts of the Pelvis?

Each hip bone is really three bones fused into one, meeting at a deep socket. Learn the parts of the pelvis — the blade, the sit bone, the front bone and the hip socket — then label them yourself in an interactive playground.
