What is "fenestra"?

Fenestra is an anatomical term referring to a small window-like opening or opening-like structure in the body. It is commonly used to describe specific openings in the bones of the skull or the inner ear. Fenestrae play important roles in the physiology of hearing and balance, allowing for the transmission of sound waves or the passage of fluid and signals within the body. These openings are precise and specialized, contributing to the overall function and coordination of various bodily systems.
