The term "crura" refers to the plural form of "crus," which means "leg" in Latin. In anatomy, crura are elongated structures that resemble legs and can be found in various parts of the body. For example, the crura of the diaphragm are two muscular extensions that help support breathing by connecting the diaphragm to the spine. In addition to the diaphragm, crura can also refer to structures in the penis and clitoris. The crura of the penis are two erectile tissues that anchor the penis to the pelvic bones, while the crura of the clitoris serve a similar function in the female anatomy, contributing to sexual arousal and pleasure.
