[also: menisci (pl)]
The meniscus (plural: meniscii, from the Greek for " crescent") is the curve in the upper surface of a liquid close to the surface of the container or another object, caused by surface tension. It can be either convex or concave, depending on the liquid and the surface.
A convex meniscus occurs when the particles in the liquid have a stronger attraction to each other ( cohesion) than to the material of the container ( adhesion). Convex menisci occur, for example, between mercury and glass in barometers and thermometers. Conversely, a concave meniscus occurs when the particles of the liquid are more strongly attracted to the container than to each other, causing the liquid to climb the walls of the container. This occurs between water and glass.
In anatomy, a meniscus (from Greek μηνίσκος meniskos, "crescent") is a crescent-shaped fibrocartilaginous structure that, in contrast to an articular disk, only partly divides a joint cavity. In humans they are present in the knee, wrist, acromioclavicular, sternoclavicular, and temporomandibular joints; in other animals they may be present in other 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.
A meniscus is a curve in the upper surface of liquid contained in an object.
Meniscus may also refer to:
- Meniscus (anatomy), crescent-shaped fibrocartilaginous structure that partly divides a joint cavity
- Meniscus (optics), a type of optical lens
