Sources & model notes

Study collection

The question selection is based on the supplied labelled study photographs. Anatomy names and relationships were cross-checked against OpenStax Anatomy & Physiology 2e. Regional structures such as the pelvis, hand and thoracic cage are identified as groups before their component structures.

Geometry

BodyParts3D © The Database Center for Life Science (DBCLS). Quiz meshes are adapted from the Human Atlas BodyParts3D collection and, where available, the higher-resolution BodyParts3D 4.3 source meshes. Adaptations: axis/unit conversion, binary packing, normals, cropping the forearm for the hand view, and manually authored learning markers.

Original dataset · 4.3 mesh distribution · 4.3 distribution license: CC BY-SA 2.1 Japan. The adapted 4.3 mesh assets in this quiz are distributed under the same CC BY-SA 2.1 Japan terms. The pre-existing Atlas 4.0 assets retain their original attribution and license notices.

The models represent adult male reference anatomy, including the pelvis. They do not reproduce the female pelvic shape in the study photograph. The coccyx is a separate, simplified four-segment supplement created for this quiz, not a recovered scan. Individual anatomy and the number of coccygeal segments can vary. Mesh resolution limits very small surface detail; marker placement indicates the teaching region.

Regions, margins, spaces and foramina are indicated by an arrow in space. These are not always raised features on a bone. The default view is chosen per question; Reset target view returns to it.

Code & rendering

Corrections to the handwritten notes

The lumbar region contains L1–L5. Common spelling variants have been normalized (for example, tibial tuberosity, trochlea, capitulum and trochanter). First/second/third cuneiform are accepted as medial/intermediate/lateral cuneiform. Bone shafts also accept “body” or “diaphysis” where appropriate.
