What is meniscus in chemistry?
A meniscus is a curve in the surface of a molecular substance (water, of course) when it touches another material. With water, you can think of it as when water sticks to the inside of a glass.
What is the meaning of meniscus tear?
The meniscus is a C-shaped piece of tough, rubbery cartilage that acts as a shock absorber between your shinbone and thighbone. It can be torn if you suddenly twist your knee while bearing weight on it. A torn meniscus is one of the most common knee injuries.
What is meniscus in laboratory?
The meniscus of a liquid is the upward or downward curve seen at the top of a liquid in a container. The nature of curve whether upward (convex) or downward (concave) depends on the surface tension the liquid and its adhesion capacity to the wall of the container.
What is a meniscus and why is it important to chemistry?
This is the downward or upward curve at the surface of a liquid in a container. Depending on how the molecules of the liquid interact, this curve may either be concave or convex. A meniscus occurs because of surface tension in the liquid and must be read at eye level.
What is the scientific term for meniscus?
Meniscus in Physics In physics, the term “meniscus” can either apply to the boundary between a liquid and its container or to a type of lens used in optics. A meniscus lens is a convex-concave lens in which one face curves outward, while the other face curves inward.
What is meniscus and types?
The menisci — the medial meniscus and lateral meniscus – are crescent-shaped bands of thick, rubbery cartilage attached to the shinbone (tibia). They act as shock absorbers and stabilize the knee. The medial meniscus is on the inner side of the knee joint. The lateral meniscus is on the outside of the knee.
Where is a torn meniscus?
A torn meniscus is a tear in the cartilage of the knee. The meniscus functions to improve the fit between the femur and the tibia, to absorb shock and distribute load in the knee, and to help move lubricating fluid around the knee. The meniscus can tear from either trauma or injury or from degeneration.
What causes a torn meniscus?
A torn meniscus is often caused by a twisting movement of the knee while bearing weight. A torn meniscus causes pain, locking, or clicking, and weakness of the knee. Exercises, medicine, and arthroscopy may be used to treat a torn meniscus.
What is meniscus measurement?
A concave surface of a liquid resulting from surface tension. The bottom of the meniscus is used to measure the volume of a liquid in apparatus such as a graduated cylinder.
What causes a meniscus?
Causes of a meniscus tear The meniscus can be torn during activities that cause direct contact or pressure from a forced twist or rotation. A sudden pivot or turn, deep squatting, or heavy lifting can lead to injury. Many athletes are at risk for a meniscus tear.
Why is the meniscus important?
The meniscus plays a vital role in maintaining the stability of the knee joint along with optimizing the tibiofemoral load transfer and distribution. This also helps in preserving the health of the articular cartilage.
What is the meniscus in simple words?
Definition of meniscus 1 : a crescent or crescent-shaped body. 2 : a concavo-convex lens. 3 : the curved upper surface of a column of liquid. 4 : a fibrous cartilage within a joint especially of the knee.
