free rings of cartilage, like washers, lying between the cartilage- covered bones in the knee, acting as extra shock absorbers; each knee has an inside (medial) and outside (lateral) meniscus; these cartilages often get damaged in sport.
A cartilage disk that acts as a cushion or shock absorber between the ends of bones in certain joints. In the knee the disc on the inner side of the knee is called the medial meniscus, and the disc on the outer side is called the lateral meniscus.
The mensci are fibrocartilaginous structures that function as "washers" - to deepen the joint surfaces, shock absorbers, assist in joint lubrication and provide joint stabilisation. Often damaged, particularly in the knee, when there is a rotational force.
Crescent shaped cartilage, usually pertaining to the knee joint, also known as cartilage. There are the medial and lateral meniscus and they serve to absorb weight within the knee and provide stability.
Crescent shaped cartilage, usually pertaining to the knee joint; also known as cartilage. There are two menisci in the knee, medial and lateral. These work to absorb weight within the knee and provide stability.
The cartilaginous portion of the knee. There is both a medial (inner) and lateral (outer) meniscus. In a healthy individual, these act as frictionless surfaces to allow easy gliding of one bone on another. In disease states, there may be breakdown of this material. If injured, the meniscus may actually tear and cause problems with instability with locking and buckling with walking.
Thin cartilaginous discs, found in the knee between the femur and the tibia, in the jaw between the mandibular condyle and fossa, that reduce friction. The menisci can be damaged by trauma or chronic stress. image Torn Meniscus
The curvature away from a flat surface where a liquid meets a solid, due to surface tension. The effect can be clearly seen through the wall of a glass tube as the surface of water in air rises up the wall of the tube.
The curved surface of a liquid in a narrow tube, caused by the tendency of a liquid to "stick" to itself and to the tube. In most cases, the liquid adheres to the tube, resulting in a concave meniscus, where the liquid is higher at the edges than in the middle. In some liquids, like mercury, however, the liquid sticks to itself more strongly, and produces a convex meniscus, where the liquid is "domed" so that it is higher in the middle. When measuring liquids, you read from the middle of the meniscus, either the bottom of a concave or the top of a convex one.
The free surface of a liquid in a container, for example, water in contact with air confined in a capillary tube. The meniscus may be convex, eg mercury vs air in glass, or concave, eg water vs air in glass.
