General Reference

  • The Cochrane Library – ”The” evidence-based medicine resource: a database of systematic reviews of medical research. Some content is subscription-only but the abstracts are free.
  • WHO Fact Sheets – Brief, clear presentations about anything from Adolescent Pregnancy to Zika virus.
  • PubMed – If it has anything to do with medicine and has been published, it’s here. A free search engine to the MEDLINE database of academic journals.
  • ICD-10 – International Classification of Diseases by WHO: source of diagnostic codes widely used in medicine.
  • Merriam-Webster Medical Dictionary – Alternatives exist but I prefer this one for its clean looks and few ads. Features sound files for pronunciation. For a list of the various prefixes, suffixes etc. in the medical jargon see also here.
  • Medscape – A free (registration required) medical news site and a useful reference of drugs, diseases, anatomy, clinical procedures etc.
  • NICE Clinical Guidelines – The UK National Institute for Health and Clinical Excellence diagnostics / treatment guidelines. While these are not necessarily identical to your national / local guidelines, it’s a very good resource anyway.
  • Medical Mnemonics – Easily remembered rules of thumb for clinical practice.
  • The Merck Manual – The fact that it’s published by the pharmaceutical giant may unsettle some people (including me); anyway, it’s a usable free textbook of medicine.
  • Whonamedit – A dictionary of medical eponyms, i.e. diseases named after people. See also the Wikipedia article.


  • Anatomy Glossary – By Dr. M. A. Arnold and Deborah Bryce.
  • AnatomyZone – Anatomy video tutorials. Viewable on the main site or Youtube.
  • BioDigitalHuman – A suberb free 3-D anatomy model. See also introductory video in Youtube.
  • BodyMaps – A cool, free 3-D anatomy viewer that allows inspection of the different organ systems to the level of individual arteries and nerves. Works well e.g. for neuroanatomy which can be difficult to grasp from 2-D images.
  • Dermatome Maps – At
  • Gray’s Anatomy of the Human Body – The 1918 edition (old, sure, but anatomy seldom changes) of the famous book in searchable online form. Another version can be found here but comes with very annoying ads.
  • Hand Kinesiology – A site hosted by University of Kansas. Interactive presentation of bones, ligaments, muscles and innervation of hand.
  • Sobotta Atlas – Online version of the respected Sobotta Anatomy Atlas.
  • Zygote Body – Another great 3-D anatomy model.


  • MetroHealthAnesthesia – This site, though a bit disorganized, contains useful basic information in compact form. Also case studies / quizzes and lectures.
  • AnaesthesiaUK – Decent articles on many anesthesiology subjects. Accessing some content (quizzes, image bank) requires registration only open for health professionals.
  • Pharmacology Simulations – A University of Florida page has interactive simulations to help understand the pharmacology of anesthetic agents. Some require registration but this is both free and hassle-free.


  • NetBiochem – Metabolism & biomolecules tutorials and quizzes by James Baggott and Sharon E. Dennis.
  • The Medical Biochemistry Page – A comprehensive review of medical biochemistry topics.
  • The Life Wire – Tutorials, quizzes and other content based on the textbook Life: The Science of Biology 7th ed. Covers the whole scope of biology including plants etc. but also contains relevant stuff for early classes in med school.


  • – very nice ECG and heart sounds tutorials.
  • Heart sounds – see also my post for Youtube links.

Clinical Chemistry

  • Blood values diagrams – Illustrative presentations of blood test reference ranges by medical student, Wikipedia author Mikael Häggström.


  • Atlas of Dermatology – From Loyola University Chicago. The site appears to have been last updated in 1996 – but it works!


  • – Online embryology course by Swiss universities: in English, French, German and Dutch!

Ear – Nose – Throat

  • Acute Otitis Media – A page dedicated to diagnosis and treatment of ear infections by Dr. David McCormick / University of Texas. Includes interactive exercises.
  • Otitis media videos – American Academy of Pediatrics hosts clips of otoscopy / tympanometry videos.



  • LUMEN Histology – Histology slides by Loyola University Chicago Stritch School of Medicine.
  • Mammalian histology – Cell biology images and 3-D models by University of Delaware.

Infectious Diseases

Occupational Health

  • OSHwiki – A wiki-format resource on subjects such as ergonomics and work safety.





  • WebPath – The Internet Pathology Laboratory for Medical Education – a fine images & tutorials site hosted by The University of Utah Eccles Health Sciences Library.
  • Virtual Autopsy – Interactive patient cases by University of Leicester.
  • Basic Medical Pathology – Quizzes etc.
  • Pathology Links – An exhaustive list of links to other useful pathology resources.


  • Pediatric Neurologic Exam – Videos of neurologic examination of children from newborn to 2,5 year old.
  • & (in Norwegian and Swedish, respectively) – Video clips about common pediatric findings. Primarily a resource for parents but also great for a junior doctor wanting to learn how different kinds of cough and respiratory difficulty look like.
  • PedsEd – Children’s Hospital of Pittsburgh Pediatrics Medical Education website. Haven’t tried this myself yet.


  • Dietary Supplement Label Database – A complete (if U.S.-specific) database of ingredients and usage instructions found on dietary supplements. By the National Institutes of Health.
  • P450 interactions – Indiana University table of cytochrome P 450 substrates, inducers & inhibitors.
