What is "extensor"?

The extensor refers to a group of muscles responsible for extending or straightening various joints in the body. These muscles work in opposition to flexor muscles, which are responsible for bending or flexing joints. Extensor muscles are found throughout the body, such as the extensor muscles in the forearm that straighten the fingers or the extensor muscles in the leg that help in extending the knee joint. The extensor muscles play a vital role in maintaining posture, generating force for movements, and providing stability to joints. Their coordinated action allows for efficient movement and function in everyday activities and athletic endeavors.

What is a "bibliography"?

A bibliography is a list of sources, such as books, articles, and other materials, that an author has referenced or consulted in the process of writing a book or document. It is usually placed at the end of the work and provides readers with the information needed to locate the original sources. The bibliography helps to credit the work of other authors and researchers, shows the research behind the text, and can guide readers to additional resources on the subject. It is commonly used in academic, non-fiction, and research-based writing.
