3D anatomy
3D anatomy (in the sidebar under Read) is a model of the whole body that you can turn, take apart and click on. It has the skeleton, joints and ligaments, muscles, heart and vessels, nerves, organs, the lymphatic system, skin and body regions: about 1,800 named structures.
Moving around
- Drag to turn the body.
- Right-drag, or drag with two fingers, to move it.
- Scroll or pinch to zoom.
- The buttons under the model turn it to face you from the front, back, left, right or top. Whole body brings all of it back into view.
Body systems
The list on the left switches each body system on or off. The page opens with the skeleton only.
- Each system downloads the first time you switch it on. Its size is shown next to it; the muscles are the biggest at about 4 MB. After that it is saved on your device, and it works offline.
- The slider under a system makes it see-through, so you can see what lies underneath. Skin starts half see-through.
- The small chips under a system switch its parts on and off, such as the muscles of the upper limb or the central nervous system. The fasciae start hidden, because they would cover every muscle.
- Muscle attachments shows on the bones where each muscle starts (its origin, in red) and ends (its insertion, in blue).
Naming a structure
Hover over a part to see its name, and click it to open it on the right. Double-click it to fly to it. You can also type a name into Find a structure: "femur", "deltoid", "vagus" or a group such as "cranial nerves". Enter opens the first match, and the arrow keys move through the list.
On a phone, tap a part. Its name shows at the top of the model; tap the name to jump to the panel about it.
The panel for a structure shows:
- its name, its side, and where it belongs ("Bones of lower limb › Bones of free part of lower limb"). Click a group to list everything in it;
- a short description, when there is one;
- its landmarks: the named points on a bone, such as the greater trochanter. Click one to show where it is.
Below it are these buttons:
| Button | What it does |

| Focus | Zooms in on the structure |
| Only this | Hides everything else, until you press Show the rest |
| Hide | Hides the structure. Show all under the model brings back everything you hid |
| Left side / Right side | Opens the same structure on the other side |
| Where it attaches | For a muscle: shows the skeleton with the muscle's origin and insertion on it, and makes the other muscles see-through |
| Ask Alfond | Asks Alfond to explain the structure, briefly and for the exam |
| Find in your notes | Searches the flashcards, quizzes and chapters for its name |
