Question: What Is The Definition Of Meniscus In Science?

What is the meniscus meaning?

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.

What is meniscus short answer?

The quick answer is the meniscus is a C-shaped piece of soft and fibrous cartilage, also known as fibrocartilage, that provides shock absorption and cushion to your knee. It is also wedge-shaped which improves joint congruency, further adding to knee stability.

What is a meniscus in food science?

menisci |-kē, -kī| or meniscuses) Physics the curved upper surface of a liquid in a tube. A cup of water, measures 8 fluid ounces, but does not weigh 8 ounces. Look up water in the dictionary. It defines one fluid 8 ounce cup of water as 236.6 grams (8.3 ounces weighed).

What is meniscus in soil science?

Menisci are a manifestation of capillary action, by which surface adhesion pulls a liquid up to form a concave meniscus or internal cohesion pulls the liquid down to form a convex meniscus. This phenomenon is important in transpirational pull in plants.

What’s 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 oil is in a jar and the oil has a curve on the top of its surface, this is an example of meniscus.

Will walking on a torn meniscus make it worse?

In serious cases, it can develop into long-term knee problems, like arthritis. In addition moving around with a torn meniscus could pull fragments of the cartilage into the joint causing larger knee issues which could requiring more significant surgery in the future.

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 best describes a meniscus?

A meniscus is a crescent-shaped fibrocartilaginous anatomical structure that, in contrast to an articular disc, 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.

What causes meniscus in science?

Why a meniscus occurs Water molecules are attracted to the molecules in the wall of the glass beaker. And since water molecules like to stick together, when the molecules touching the glass cling to it, other water molecules cling to the molecules touching the glass, forming the meniscus.

Why do we need to read the lower meniscus and not the upper meniscus?

Why do we need to read the lower meniscus and not the upper meniscus? The lower meniscus must be read while measuring the volume of colourless or transparent liquids but the upper meniscus while using colured ones because the phase boundary in the colourless liquid is clearly visible so it is easy to read it.

What is the correct level at which to read a meniscus?

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.

How does the human body use adhesion?

Without this flow, your body’s cells would not rehydrate and vital communication between your brain and body would slow. Capillary action occurs because water is sticky, thanks to the forces of cohesion and adhesion. This surface tension permits water to hold up substances heavier and denser than itself.

What determines the shape of a liquid’s meniscus?

When liquid water is confined in a tube, its surface (meniscus) has a concave shape because water wets the surface and creeps up the side. When liquid mercury is confined in a tube, its surface (meniscus) has a convex shape because the cohesive forces in liquid mercury tend to draw it into a drop.

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. Convex menisci are read from the top of the curve at eye level.
