An excessive rise in body temperature when heat gain exceeds loss. It differs from fever with an increased regulated temperature target, even though both can produce a high thermometer reading.
Breakdown of skeletal muscle that can complicate intense generalized muscle spasms.
A disorder affecting the respiratory system or its function. Airflow limitation, impaired gas exchange and disturbed control of breathing are different routes to respiratory disability.
A disorder affecting the heart or blood vessels. The category spans electrical, mechanical and vascular problems, so it does not imply that every member has the same risk factors or mechanism.
Historical description of pathological products associated with scrofulous or tuberculous illness, often including caseous debris. It does not identify one chemical substance or prove deposition of a preformed material from blood.
A disease whose lesions occur at corresponding sites on the two sides of the body, with similarity of form or extent. It is a distributional description rather than one causal diagnosis.
Historical constitutional predisposition invoked to explain scrofulous illness. It should be distinguished from the modern infectious cause and host risk factors of tuberculosis.
Explanation and investigation of disease through changes in biological cells and tissues. Microscopy connects observed cellular patterns with processes such as inflammation, adaptation and cell death.
Inflammation of an anatomical joint. Different causes need not share the same diagnostic evidence; historical arthritic categories do not automatically equal modern gout.
Reduced desire to eat. It is a symptom with many physiological and psychological explanations, distinct from inability to swallow or lack of food availability.
A descriptive historical finding of hard, indurated tissue. Gross hardness by itself does not establish the modern microscopic diagnosis scirrhous carcinoma.
Correlation of anatomical changes with disease and clinical observation. Gross findings and clinical symptoms do not, on their own, necessarily identify a modern microscopic mechanism.
Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

Source. - local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
