Zygote Body
Zygote Body is a 3D anatomy viewer from Zygote 3D. Its site describes viewing any combination of muscles and bones to learn where muscles start and end. Premium adds saved scenes, annotations and more control over what is visible. The site lists orbit rotation, the part hierarchy, slice, explode and the quiz as premium tools.
BioDigital Human
BioDigital calls its product an interactive 3D software platform for visualizing anatomy, disease and treatment. The free Personal plan includes 10 views of 3D models a month and 5 saved models. The plan runs on the web and in apps for iOS and Android. Embedding models in a school's learning system belongs to the paid plans.
Visible Body
Visible Body makes interactive anatomy and biology products for the web and mobile devices. Its site lists free resources such as flashcards, tours and lesson plans next to its paid courseware. In May 2019 the company announced more than 100 free 3D anatomy models on its website, viewable in augmented reality on a phone.
Open Anatomy Browser and BodyParts3D
The Open Anatomy Project publishes free digital atlases from a hospital laboratory. Its browser runs in Chrome, Firefox and Safari on a desktop computer, and the project describes the browser as prototype quality.
BodyParts3D is a database of 3D anatomy from the Database Center for Life Science in Japan. Its description calls it a whole-body model of an adult human male, split into segments. The license is CC BY 4.0, so the models can be reused with credit.
This site's 3D anatomy viewer
The 3D anatomy viewer on this site is built on BodyParts3D. The viewer has 1,659 named parts in 12 body systems and needs no account. Any part can be tapped for its name, hidden, faded or pulled out, and whole systems switch on and off.
Three views open on one subject each. The 3D skeleton has a bone quiz. The organs of the body can be found by side and by level. The 3D muscles are named part by part. The viewer shows one adult male body, and it is a tool for learning, not for diagnosis.
3D anatomy in Google Search
Google Search on a phone shows 3D anatomy too. Google's blog said on 8 May 2020 that Search shows 11 human body systems in augmented reality, built with BioDigital. Searching for a body system and tapping View in 3D opens a labeled model.
