What is the definition of meniscus in science?


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 meniscus easy definition?

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.

What is an example of meniscus in science?

A convex meniscus appears when molecules of liquid are strongly attracted to each other rather than to the wall of container. Most liquids, including water, show a concave meniscus but a great example of a convex meniscus is liquid mercury in a glass container.

What is a meniscus for kids?

The meniscus is a crescent-shaped wedge of thick, rubbery cartilage that is located between the shinbone (tibia) and the thigh bone (femur). The meniscus acts as a shock absorber, or cushion, for the knee joint during weightbearing, and prevents your femur and tibia from grinding against each other.

What is meniscus level in physics?

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.

What is a meniscus in chemistry quizlet?

What is a meniscus? A curve in the surface of a liquid substance(such as water) when it touches another material.

What is meant by meniscus of mercury?

Mercury shows a convex meniscus (the centre is higher than the edges), because internal cohesive forces are stronger than the force between the glass wall and the metal. In contrast, water exhibits a concave meniscus, because the attraction between the wall and the water is stronger than the water’s internal cohesion.

What is meniscus in Marathi?

the curved upper surface of a liquid in a tube. translation of ‘meniscus’ दुसर्‍या बाजुने अंतर्गोल असणारे भिंग, एका बाजूने बहिर्गोल

Can a 7 year old tear a meniscus?

Once a rare diagnosis in pediatric and adolescent athletes, a torn meniscus is now commonly recognized. This condition is seen in athletes playing sports such as football, soccer, basketball, and hockey. Meniscus tears impede the knee’s function and range from minor to severe depending on the extent of damage.

Can an 11 year old tear meniscus?

Active children and teenagers sometimes can have structural injuries to their knees. The meniscus, which is a shock-absorbing cartilage in the knee, can tear; often these painful injuries are treated surgically, using a minimally-invasive procedure called arthroscopy.

Is the meniscus a ligament?

Menisci rests between the thigh bone femur and the tibia and there are two knee joint ligaments. They are a type of cartilage in the joint. The rubbery texture of the menisci is due to their fibrocartilagenous structure. Their shape is maintained by the collagens within them.

What is the function of meniscus?

They are very tough, smooth and rubbery and their cushioning of the joint keeps it stable. The meniscus is often thought of as being shock absorbers between the thighbone and the shinbone. They work to help in the reduction of wear and tear on the knee’s cartilage and bones and assist in guiding movement.

What is meniscus made of?

The meniscus cartilage itself is made up of a softer fibrocartilage. The knee has two C-shaped meniscus structures made of a softer fibrocartilage. These structures are anchored to the tibia by the peripheral capsular attachments of the menisci, which allow them more mobility within the joint.”

Where are meniscus located?

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 type of tissue is the meniscus?

dense connective tissue

Meniscus tissue is composed of outer, dense connective tissue and inner fibrocartilage regions (Fig. 1.4(b)) (Verdonk et al. 2005). The outer region is vascularized dense fibrous connective tissue that connects to the internal knee joint capsule.

What holds meniscus in place?

The menisci are attached to each other via the transverse ligament.

Is the meniscus the same as cartilage?

The meniscus is a different type of cartilage. This type acts as a shock absorber between bones. 1 The meniscus is not attached to the bone like articular cartilage. Instead, it sits between the bone ends to cushion the joint.

What are the 4 ligaments of the knee?

The knee has 4 major ligaments. Ligaments connect bones to each other. They give the joint stability and strength.
They are:

  • Anterior cruciate ligament (ACL). …
  • Posterior cruciate ligament (PCL). …
  • Medial collateral ligament (MCL). …
  • Lateral collateral ligament (LCL).

What is the cushion in your knee called?

Cartilage is a type of firm, thick, slippery tissue that coats the ends of bones where they meet with other bones to form a joint. Cartilage acts as a protective cushion between bones.
