Chemical regulation of ventilation, including the combined stimulus of hypoxia, hypercapnia and acidity.
An antibody preparation that can bind and neutralize unbound tetanospasmin. It supplies passive protection and differs from a vaccine, which induces the recipient’s own immune response.[ref]
Orchitis is inflammation of the testis. Causes can differ, and associated epididymal inflammation is termed epididymitis. Distinguishing the affected anatomical compartments is important because a painful scrotum can involve structures other than the testicular tissue itself.
A condition-dependent carbon dioxide fraction at which a specified candle flame is extinguished in a specified protocol. Distinguish a demonstrated sufficient fraction from the least sufficient fraction.
Infection acquired before birth; an infant may initially lack visible signs. Historical “hereditary” terminology does not imply Mendelian inheritance.
Primary lesion classically associated with acquired syphilis; appearance alone does not establish the diagnosis.
The unique readability theorem asserts uniqueness of the outer formation rule and its immediate components in a logical formula. For the fully parenthesized language with negation and implication, every formula is uniquely a variable, a negation of one formula, or an implication between an ordered pair of formulas. It gives a well-defined syntax tree and licenses recursive definitions and structural induction on formulas.
A joint capsule surrounds a synovial joint, with a fibrous outer layer and an internal synovial membrane at appropriate surfaces. It encloses the joint cavity while allowing movement. Regional thickening and attachments constrain motion differently in different directions.
The glenoid labrum is a rim of fibrocartilaginous tissue around the glenoid cavity. It deepens the socket and contributes attachment and stability at the glenohumeral joint. Stability also depends on the capsule and muscles, so the labrum is one component of a coupled system.
Synovium denotes the synovial membrane and its associated tissue. It forms an active interface between the joint cavity and the vascular supporting tissue. The term therefore refers to tissue, whereas synovial fluid refers to the material in the cavity.
Synovial fluid is the specialized fluid within a synovial joint. It supports lubrication and exchange with the avascular articular cartilage. Its volume, composition and mechanical behavior are distinct properties, so a change in one need not identify the cause of every joint symptom.
The synovial membrane lines the internal non-cartilaginous surfaces of a synovial joint capsule. It contributes to production and regulation of synovial fluid. It does not simply extend as the same lining over the load-bearing articular cartilage.
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.

- 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
