In anatomy, a<unk> is a moon-shaped figure. It usually refers to either of two specific parts of cartilage of the knee. The knee contains a lateral<unk> and a medial<unk>  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 "C" shape - a term which has been largely dropped by the medical profession, but which led to the menisci being called knee 'cartilages' by the lay public.
Although menisci are largely associated with the knee, they are similar in function to structures called articular disks in other parts of the body.
