Data, sources and limits
Kalviyogi MBBS is built on published reference datasets. See where the material comes from, what each collection contains and where its coverage ends.
Medical disclaimer. Kalviyogi MBBS is an educational platform. It is not a substitute for professional medical diagnosis or treatment.
Model coverage
The two human datasets are separate collections with different scope. They are not a male and a female version of the same model, and a structure missing from one is not evidence about the body — it is evidence about the dataset.
MaleBodyParts3D
An adult male reference anatomy. It does not contain every human structure or variation.

A female reference assembly: whole-body surface, selected organs, and a detailed female reproductive tract. Skeleton and muscle coverage is partial and this is not a complete full-body internal atlas.

Seven authored teaching models of plant structure. Every piece is drawn for teaching rather than scanned from a specimen, and each topic states what it represents and at what scale.
Original geometry authored for this viewer. Explanations written from OpenStax Biology 2e (CC BY 4.0 text).NEET 3DAuthored teaching models
Chapter-linked 3D teaching models of biological structures and processes. Molecular, taxonomic and ecological scenes use schematic shapes and mixed scales; they are not specimen scans or predictive experiments.
Original schematic geometry and explanations authored for this educational viewer. Scientific and Tamil terminology review remains pending.Female mode has no stomach, because the source collection contains none. Eleven pelvic pieces in that mode are authored teaching schematics, marked as such wherever they appear, and have not been reviewed by an anatomist.
Curriculum coverage
1 of 19 MBBS subjects open in the atlas: anatomy, across 8 of 11 regions and 99 listed structures. Physiology has written chapter notes only. The remaining subjects hold no content.
NEET Biology lessons and processes
The NEET Biology library adds English and Tamil lessons for all 32 current NCERT chapters, original practice questions, and 13 interactive teaching labs. The NEET 3D collection links every chapter to 39 teaching scenes and 54 staged processes, with selectable structures and layers. Search by chapter or process, then open an animation paused for reading. Multiple models are available for chapters with complementary structure and process scenes.
Organised by the 32 chapters in NCERT Biology, 2026–27 reprints, with NEET 2026 topic supplements. Notes and questions are original study material; questions are not previous-year papers. Teaching models are simplified. Subject and Tamil terminology review is pending.
Human anatomy atlas chapter coverage
16 NCERT chapters open at related structures in the human anatomy atlas. Chapters outside that collection are listed below; the separate NEET 3D collection provides chapter-linked teaching scenes.
NCERT rationalised both Biology books in 2023 and the NTA has revised the NEET syllabus since. Chapter numbers moved and some topics were dropped, so this maps by unit and chapter title rather than by number. Check the current NTA syllabus before relying on it: this is a study aid, not a syllabus.
Class 11 — The Living World · Biological Classification · Biomolecules · Cell Cycle and Cell Division · Respiration in Plants · Plant Growth and Development
Class 12 — Reproductive Health · Principles of Inheritance and Variation · Molecular Basis of Inheritance · Evolution · Human Health and Disease · Microbes in Human Welfare · Biotechnology: Principles and Processes · Biotechnology and its Applications · Organisms and Populations · Ecosystem · Biodiversity and Conservation
Tamil Nadu State Board carries Biology as separate Botany and Zoology volumes, in a different chapter order. NEET is set from NCERT, so this atlas maps to NCERT and leaves the state-board ordering alone. Structure names appear in Tamil wherever a Tamil term has been written; the language picker says how far that goes.

Known limitations
- No content on this site has been reviewed by a doctor, an anatomist or a medical faculty member.
- Translations are unreviewed. Twelve of the fourteen languages cover interface controls only.
- Botany models are authored teaching geometry, not scanned specimens, and no botanist has reviewed them.
- Geometry is simplified for the web. This is an educational reference, not a diagnostic, surgical or identification tool.
- Performance has not been measured on a broad range of physical hardware; no frame rate is claimed.
Not built yet, and why
MBBS Subjects
Partly builtThe full four-year curriculum, with anatomy opening directly into the 3D atlas region by region.
Anatomy opens in 3D and Physiology has reading material. The other seventeen subjects are listed without content yet.
Bilingual Learning
Partly builtEnglish and Tamil Biology lessons, plus fourteen atlas interface languages. Tamil and Hindi also carry structure names.
Subject-matter review of the translations is pending. Most atlas languages cover interface controls only.
Viva & Spotter Practice
Partly builtIdentify the highlighted structure, drawn from whatever is currently on screen.
Questions are generated from the model itself. There is no written viva bank: producing one without a named source and a faculty review would be inventing medicine.
Classroom & Smart Board
Partly builtA responsive 3D lesson space with drawing, spotlight, laser pointer and presentation tools, plus larger controls on smart boards.
Student joining and shared live classroom sessions are not available.
Clinical Correlations
Not built yetConditions, signs, examination relevance and exam pearls attached to each structure.
Needs sourced, faculty-reviewed clinical text. None exists for this project, and writing it unsourced would be fabricating medicine.
Radiology
Not built yetX-ray, CT, MRI and cross-sectional anatomy alongside the 3D model.
Needs licensed or openly published imaging series. This project holds none, and drawing imaginary scans is not an option.
Histology
Not built yetOrgan to tissue to cell, with labelled microscopic views.
Needs real microscopy images. The botany atlas has a plant cell at this scale; the human equivalent has no source here.
Embryology
Not built yetWeek-by-week development with congenital correlations.
No developmental sequence is modelled, and animating one from guesswork would teach the wrong shapes.
AI Medical Tutor
Not built yetContext-aware explanation of whatever is selected, in English or Tamil.
Needs a server to hold the API key. A key shipped in the browser is a key given away, so this waits for a backend.
