Meniscus (anatomy)

Uncommon card · No. 136648

A meniscus (pl.: menisci or meniscuses) is a crescent-shaped fibrocartilaginous anatomical structure that, in contrast to an articular disc, only partly divides a joint cavity. In humans, menisci are present in the knee, wrist, acromioclavicular, sternoclavicular, and temporomandibular joints. Generally, the term "meniscus" is used to refer to the cartilage of the knee, either to the lateral or medial meniscus. Both are cartilaginous tissues that provide structural integrity to the knee when it undergoes tension and torsion. The menisci are also known as "semi-lunar" cartilages, referring to their half-moon, crescent shape.
