What is meniscus in science definition?
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. • Water Science School HOME • Water Properties topics •
What is a meniscus and how is it used?
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.
How does a scientist use the meniscus?
The formation of menisci is commonly used in surface science to measure contact angles and surface tension. In a surface tension measurement, the measurement probe has a contact angle of zero and the surface tension can be obtained by measuring the mass of the menisci.
What is the meniscus and why is it important?
The meniscus plays two important roles within the knee. A meniscus is a critical shock absorber within the knee. The meniscus also provides stability within the knee.
What is an example of meniscus?
The definition of a meniscus is the fibrous cartilage in a knee joint, or the curved upper surface of liquid that touches the sides of a jar, or a lens that is convex on one side and concave on the other. When you have a lens of a camera that curves out on one side and in on the other, this is an example of meniscus.
What does a meniscus do?
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.
What do you do for a meniscus tear?
Treating a meniscus tear
- Rest your knee. Use crutches to avoid any weight bearing on the joint. Avoid any activities that worsen your knee pain.
- Ice your knee every three to four hours for 30 minutes.
- Compress or wrap the knee in an elastic bandage to reduce inflammation.
- Elevate your knee to reduce swelling.
Do you read from the top of the meniscus?
The key to getting an accurate reading, is to measure the center of the meniscus whether it be concave or convex. E.g. with a concave meniscus, measure the bottom of the meniscus and for convex meniscus, take the reading from the top of the meniscus.
How do you read a meniscus volume?
A meniscus occurs because of surface tension in the liquid and must be read at eye level. For a concave meniscus, the correct volume will be read at the bottom of the curve. For a convex meniscus, the opposite is true and the correct reading will be at the top of the curve.
What is upper meniscus and lower meniscus?
Concave menisci are read from the bottom of the curve at eye level. A meniscus is a curve formed on the upper surface of a liquid inside a container. This curve is formed by the surface tension between the liquid and the container holding the liquid. A common liquid that forms a convex meniscus is liquid mercury.
Normally, liquid will curve at the edges of the surface where the liquid touches the container because water molecules are more attracted to glass than to each other. We need to read the level at the bottom of the meniscus to measure a volume of liquid in a graduated cylinder.
Which meniscus of acid Hematin is considered?
When students look at the surface, the water level is not straight. Measurement should be therefore done at the lowest point. However, in the case of coloured liquids observing this phase boundary (spatial interface, called a phase boundary) is not possible, hence only the upper meniscus is considered.
Which meniscus is more important?
There are some important differences between the medial and lateral meniscus. The medial meniscus is more firmly attached to the tibial condyle by the deep medial collateral ligament (MCL); the lateral meniscus is relatively mobile. Thus, the medial meniscus is a more important stabilizer.
Does the meniscus provide stability?
The meniscus provides stability to the joint and act as “bumpers” for the knee joint. When the knee is twisted during sports or other activities, the meniscus can become caught between the femur and the tibia. The meniscus can then be torn away from its attachments on the outside edges.
