What does cartilage mean for kids?

Kids Definition of cartilage : tough flexible tissue that makes up most of the skeleton of vertebrates during early development and except for in a few places in the body (as the nose or outer ear) is replaced by bone.

Subsequently, one may also ask, what is cartilage simple?

From Wikipedia, the free encyclopedia. Cartilage is a flexible connective tissue found in many parts of the body. It can bend a bit, but resists stretching. Its main function is to connect bones together. It is also found in the joints, the rib cage, the ear, the nose, the throat and between the bones of the back.

Subsequently, question is, what is cartilage and ligaments? A ligament is a band of tissue that connects bones to each other, and ensures the joint is stable, whereas cartilage is line of connective tissue that works as a padding between the bones. It is made up of elastic fibres and, like ligaments, collagen.

Also to know is, what is cartilage for?

Cartilage is a resilient and smooth elastic tissue, a rubber-like padding that covers and protects the ends of long bones at the joints, and is a structural component of the rib cage, the ear, the nose, the bronchial tubes, the intervertebral discs, and many other body components.

What is cartilage and why is it important?

Cartilage connective tissue is important because it provides support, but is less rigid than bone. It also allows for some flexibility of movement, but has more stability than muscle. The extracellular matrix of cartilage is produced by cells called chondroblasts.

Does cartilage grow back?

Although articular cartilage is not capable of regrowing or healing itself, the bone tissue underneath it can. By making small cuts and abrasions to the bone underneath the area of damaged cartilage, doctors stimulate new growth. In some cases, the damaged cartilage is cleared away completely to do this procedure.

What are the three types of cartilage?

There are three types of cartilage:

Hyaline - most common, found in the ribs, nose, larynx, trachea. Is a precursor of bone.
Fibro- is found in invertebral discs, joint capsules, ligaments.
Elastic - is found in the external ear, epiglottis and larynx.

What is another word for cartilage?

Synonyms for cartilage

bony process.
ossein.
osseous matter.

What word best describes cartilage?

Scientific definitions for cartilage A strong, flexible connective tissue that is found in various parts of the body, including the joints, the outer ear, and the larynx. During the embryonic development of most vertebrates, the skeleton forms as cartilage before most of it hardens into bone.

How many types of cartilage are there?

three types

What are the characteristics of cartilage?

Cartilage is a type of connective tissue composed of special cells known as chondrocytes along with collagen or yellow elastic fibers. The fibers and the cells are embedded in a firm gel like matrix rich in mucopolysaccharides. Cartilage is not as hard and rigid as bone. It is much more flexible and elastic.

What is the function of bone?

Bones have many functions. They support the body structurally, protect our vital organs, and allow us to move. Also, they provide an environment for bone marrow, where the blood cells are created, and they act as a storage area for minerals, particularly calcium.

What is the medical term for bone?

Oste/o = Bone. Osteon = bone.

How do you know if your cartilage is damaged?

Symptoms of cartilage damage

joint pain – this may continue even when resting and worsen when you put weight on the joint.
swelling – this may not develop for a few hours or days.
stiffness.
a clicking or grinding sensation.
the joint locking, catching, or giving way.

How do you repair cartilage?

It requires two surgeries.

First, the patient undergoes arthroscopic surgery to remove a small piece of healthy cartilage from a non-weight bearing area of the knee joint.
Three to five weeks after the first surgery, a second surgery is performed to implant the newly grown cartilage cells into the affected knee joint.

What can cause cartilage damage?

Articular cartilage can be damaged through accidents, such as a tear to the anterior cruciate ligament (ACL), or degenerate slowly over time, eventually leading to osteoarthritis. Poor alignment of the joint, excessive weight, excessive activity, overuse, or injury can all cause cartilage to wear away.

Does cartilage heal?

While cartilage is very beneficial to the body, it does have a drawback: it doesn't heal itself as well as most other tissues. The cartilage cells known as chondrocytes do not often replicate or repair themselves, which means damaged or injured cartilage will not likely heal well without medical intervention.

What is the main difference between the different types of cartilage?

Elastic cartilage contains more and larger chondrocytes than the hyaline cartilage. They are more closely packed and only one chondrocyte per lacuna. All the cartilage is covered by perichondrium. Exhibits less accumulation of glycogen and lipids than the hyaline cartilage.

Why are there no blood vessels in cartilage?

In cartilage, there are no blood vessels or nerves. Instead, cartilage cells (chondrocytes) exchange nutrients and waste through diffusion with surrounding “ground substance”. This is possible because, unlike bone, cartilage is a thin structure composed of chondrocytes which secrete an extra-cellular matrix.

Where are cartilage found?

Cartilage is a connective tissue found in many areas of the body including: Joints between bones e.g. the elbows, knees and ankles. Ends of the ribs. Between the vertebrae in the spine.

How can you protect your cartilage?

Try glucosamine and chondroitin supplements. They may help protect your cartilage, though there's no proof that either one will rebuild it or slow down your arthritis. Some studies suggest they can ease your pain.

How does cartilage grow?

Cartilage can grow in two ways: Interstitial growth - chondrocytes grow and divide and lay down more matrix inside the existing cartilage. Appositional growth - new surface layers of matrix are added to the pre-existing matrix by new chondroblasts from the perichondrium.

Is cartilage a ligament?

A ligament is an elastic band of tissue that connects bone to bone and provides stability to the joint. Cartilage is a soft, gel-like padding between bones that protects joints and facilitates movement.

Is cartilage a shock absorber?

Articular cartilage acts as a shock absorber, cushioning bones against impacting each other during a weight-bearing activity, such as walking or jogging.
