About
Human biology, explained properly.
Surgeonring is a visual reference for anatomy, physiology, biology and histology. It exists because most free anatomy material online is either a list of facts with no mechanism, or a clinical page written for someone who already has the training. We write the middle: the explanation that makes the facts stick.
What is here
30 illustrated guides in three sections. Each follows the same five-part structure, so once you have read one you know how to read all of them.
How we write
- Sourced from standard texts
Every guide is written against the reference works clinicians and students actually use — Gray's Anatomy, Guyton and Hall, Ross and Pawlina, Robbins and Cotran, Janeway — supplemented by named primary papers and current professional guidelines. Each article lists its sources, and the emergency and tissue guides link them.
- Numbers are checked, not remembered
Any figure we quote — a filtration rate, a survival percentage, a conduction speed — is taken from a cited source rather than from general recollection. Where a number is a range or is genuinely disputed, we say so instead of picking the tidiest version.
- Dated and reviewed
Every article carries a publication date and a last-reviewed date, both in the page and in its structured data. Guidance changes, particularly in emergency medicine, and an undated health page is not trustworthy however good it was on the day it was written.
- Explanation over recall
We write the mechanism, not the mnemonic. A guide should leave you able to work out the next question yourself, which is why every study moves in the same order from structure, to function, to the cells, to the tissue, and only then to what goes wrong.
- Not medical advice, and clear about it
Nothing here is a diagnosis or a treatment plan for a particular person. Every article carries a disclaimer that says so plainly. The emergency guides describe recognised first-aid practice and tell you to call for help — they are not a substitute for doing so.
- Owned, licensed artwork
The anatomical plates are from Henry Vandyke Carter's engravings for Gray's Anatomy, published in 1918 and in the public domain worldwide. Each file's licence was verified before it was used, and the figure number is printed with the image.
Who writes it
Articles are researched, written and edited by the Surgeonring Editorial Team, working from the reference texts and guidelines listed at the foot of each guide. Where a guide states a figure or a recommendation, the source it came from is named on the page so you can go and check it.
We are not your clinician and cannot be. Surgeonring is written for people who want to understand how the body works — students, nurses, and anyone curious enough to read 2,000 words about a kidney. If you have symptoms, or a decision to make about your own health, that is a conversation for a qualified professional who can examine you.
Corrections
If something here is wrong, we want to know, and we would rather hear it from you than leave it up. Send the article, the sentence, and ideally the source you think is correct. Substantive corrections change the article and its reviewed date.
