What you find in Espiral Atlas
Human body in 3D
Skeleton, muscles, vessels, nerves and organs, for the male and the female body. Rotate, zoom in, isolate and make transparent whatever gets in the way.
An entry for every structure
Origin, insertion, innervation, blood supply, action and clinical notes. Every field cites its source, and anything that still needs checking is marked.
Clinical correlation
Fractures, injuries and clinical pictures linked to each structure, to connect anatomy with what you will see on the ward.
Pin quiz
Click the 3D piece and answer: the atlas asks and corrects. There are also flashcards to review what you got wrong.
By region and by system
Study by upper limb, thorax, abdomen… or by system: skeletal, muscular, nervous, cardiovascular and more.

From anatomy textbooks and scientific articles. We write the text in our own words, each field cites where it was checked, and anything unconfirmed is flagged.
Who is it for?
Medical students and students of other health programs who want to study anatomy and prepare for practical exams.
Do I need to install anything?
No. The atlas runs in the browser, in Portuguese, Spanish or English.
