Pelvis anatomy in 3D

Beta

Explore the two hip bones and the sacrum, shown together as in the textbook section on the pelvic girdle and pelvis.

Beta

Interactive 3D atlas

Loads about 9 MB of 3D data the first time. Works best on a laptop or a recent phone.

Study the pelvis in 3D

Explore the two hip bones and the sacrum, shown together as in the textbook section on the pelvic girdle and pelvis.

Turn and zoom

Drag to rotate, scroll or pinch to zoom, and tap any part to see its name and explanation.

Labels and standard views

Switch labels on or off and jump to front, back, side, top and bottom views, with an orientation cube.

Section cuts

Cut through the structure in transverse, coronal or sagittal planes and slide the cut through it.

Explode and see-through

Pull the parts apart, or make the outer layers faint to see what is inside.

Guided tour

Follow the "Bone by bone" tour one step at a time, or press Play and let the camera fly to each part.

Parts in this model

3 named parts, each with the FMA identifier the dataset gives it. Tap a group in the app to show or hide it.

  • Hip Bone2
  • Sacrum1

Guided tour: Bone by bone (2 steps)

Each step highlights the parts it talks about. The sentence is quoted word for word from OpenStax Anatomy and Physiology 2e.

  1. 1. Hip Bone

    The hip bone, or coxal bone, forms the pelvic girdle portion of the pelvis.
    OpenStax, 8.3 Hip Bone

  2. 2. Sacrum

    It is formed by the fusion of five sacral vertebrae, a process that does not begin until after the age of 20.
    OpenStax, 7.3 Sacrum and Coccyx

What this model does not show

This workstation is for the male body. The female pelvis has its own workstation, built from different source models.

Where the data or the textbook has a gap, the atlas says so instead of filling it in.

Questions

What can I see in the pelvis model?

The model has 3 named parts in 2 groups: Hip Bone, Sacrum.

What is the "Bone by bone" tour?

It is a guided tour of 2 steps. Each step highlights the parts it describes and shows a sentence quoted from OpenStax Anatomy and Physiology 2e. Press Play to let the camera fly to each step for you.

What is missing from the pelvis model?

This workstation is for the male body. The female pelvis has its own workstation, built from different source models.

Where does the information come from?

The 3D shapes come from the BodyParts3D dataset (and, for the female pelvic region, the Human Reference Atlas). Every explanation is a sentence quoted word for word from the open textbook OpenStax Anatomy and Physiology 2e, with a link to its section.

Can I use it to diagnose or treat anything?

No. The atlas is for learning only. It is a beta version and has not yet been reviewed by an anatomy educator.
