There are a million med school resources out there – the hard part is narrowing them down.
In general:
PogoFrog – A medical search engine.
Uptodate – I hope your med school has a subscription. It’s the medical wikipedia! (Not that you should totally ignore the other wikipedia…)
Medical Abbreviations – Wikipedia recently split their medical abbreviation list into sections, so you have to choose the letter of the alphabet you’re looking for on this page. Lame, but everything’s still there, so I guess it’s still as useful as it used to be.
Free Medical Textbooks – Does what it says on the tin.
Anatomy Guy – Not just anatomy videos – also histology and path lectures. Though some of the lectures are a bit dry, they should get bonus points for 1) making them available to everyone and 2) featuring cadaver images instead of powerpoint slides. Fantastic.
Awesome Medical Animations – If you need something visualized. No guarantees on accuracy, but the company looks legit and I like their stuff.
Anatomy
U of Michigan: Medical Gross Anatomy Resources Take the quizzes like your life depends on it. They also have dissection videos, if you’re not into winging the dissection.
UC Davis: Eye Simulator (Virtual Patient): You have to click “Eye movement simulator” in the top frame. This site will condense 3 hours of extraocular muscle studying down into 10 minutes. Take the quizzes.
Anatomy Mnemonics: You have to wade through a lot that don’t work before you find something great, but it can be worth it.
Net Anatomy: Your school has to have a subscription, sadly. It’s a labeled atlas for “gross anatomy” and “cross-sectional anatomy”, both sites using actual cadaver images. This is fantastic if you don’t want to shell out $60 for a McMinn’s atlas or can’t follow all of the tiny arrows in Rohen’s.
Radiology Masterclass: Never used this in anatomy. But I came back to it again and again in pathology, and maybe I should’ve used it in anatomy to begin with.
Histology
Blue Histology: First of all, this is from the University of Western Australia, which is awesome. (Australia!) Secondly… quizzes. I like them, if you haven’t noticed.
Loyola University Histology: More quizzes! It seems like the trick to histology is seeing as many pictures as possible until you just start recognizing structures.
Shotgun Histology: Videos made by a pathologist for each type of tissue. He walks you through exactly what you should be noticing, and how you can be expected to notice it.
Pathology
Pathguy: It’s brilliant and easy-to-read, but hard to find information. I wish the entire website was published in book-format, but it’s worth the effort to just google ” site:www.pathguy.com ‘insert path topic here’ ‘”
WebPath: Great labels on their slides, easy navigation.
Pharmacology
Solid Pharmacology: Each lecture is given by a clinician in the field, and out of the 12 or so I’ve watched so far, they’re all very good lectures. There’s short mock-commercials between segments to give you silly ways to remember some of the drugs, and the worksheet they give you for each lecture is really helpful in consolidating the information.
Biochemistry
The Medical Biochemistry Page: Straightforward explanations of what turns what into what and why.
Embryology
Human Embryology Animations: Because the people at Indiana University love you and want you to be happy.
How Sonic Hedgehog Works (Video): Sure, you could ignore the flashy, 90’s-style narrative video and just study the diagram. But WHERE’S THE FUN IN THAT.
Cardiovascular
EKG Review Look at pathological EKGs by categories. An advanced quiz is available.
EKG Quiz Much better quiz format for beginners.
EKG Online Flashcards1 and Online Flashcards 2 Props to the student who put these up. Flashcard people can rejoice that we don’t have to make our own.
Neuroanatomy
Interactive Neuroanatomy Atlas – Looks useful.
Clinical Stuff
U of Florida: Physical Exam Study Guides – Great study guides, I highly recommend them.
Sample SOAP Notes For Each Clerkship
Medfools.com – Lots of templates for patient write-ups and rounding. Probably more useful for M3s than anyone else.
SoapNote.org – I especially like this one for when I’m trying to figure out how to phrase a normal result on a specific examination.
OnSurg: Student Web Guide – For everything surgery-related.
Dermatology
DermAtlas – a free online dermatology atlas? Awesome.
Action Potential 
Great share. I really love your blog. 🙂
I’m clinical librarian on inpatient rounds with medical students, and your blog helps me know and understand what it’s like for them, as well as great tips to share. Thank you!
the only thing that got me through haematopathology (and pretty good at all the other topics it touches on as well) – http://www.pathologystudent.com/
This page is FANTASTIC!! Thank you for all these resources. 🙂 Feel tempted to add the same thing to my blog, too, but I don’t really have a very large collection of resources.
