Which is true of cartilage?

Which is true of cartilage?

It is not as hard and rigid as bone, but it is much stiffer and much less flexible than muscle. The matrix of cartilage is made up of glycosaminoglycans, proteoglycans, collagen fibers and, sometimes, elastin. Cartilage does not contain blood vessels (it is avascular) or nerves (it is aneural).

What is true about bone and cartilage?

They are both made up of cells embedded in an extracellular matrix. It is the nature of the matrix that defines the properties of these connective tissues. Cartilage is thin, avascular, flexible and resistant to compressive forces. Bone is highly vascularised, and its calcified matrix makes it very strong.

What is an cartilage?

Cartilage a strong and smooth substance made up of “chondrocytes,” or specialized cartilage cells, that produce a matrix of collagen, proteoglycans (a special type of protein) and other non-collagenous proteins. These materials help cartilage attract water and give it its shape and specific properties.

How many statements are true for cartilage?

Correct answer 5. All of the statements are TRUE.

What are the 3 types of cartilage?

There are three types of cartilage: hyaline, fibrous, and elastic cartilage.

• Hyaline cartilage is the most widespread type and resembles glass.
• Fibrous cartilage has many collagen fibers and is found in the intervertebral discs and pubic symphysis.

Which is the biggest cartilage?

thyroid cartilage
The thyroid cartilage is the largest of the nine cartilages that make up the laryngeal skeleton, the cartilage structure in and around the trachea that contains the larynx.

What body part contains cartilage?

As well as being found in the joints and the discs of the spine, cartilage makes up entire parts of the body. Typically, cartilage is used in passageways into the body that are kept permanently open. These include the nose, the outer ear and the tubes of the lungs, known as the bronchioles.

How do you heal cartilage?

Treatments for cartilage damage rest the affected joint. elevate the affected limb and apply an ice pack to the joint regularly. take ordinary painkillers, such as paracetamol or non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen.

Can you repair cartilage?

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 cartilage is most springy and flexible?

In the embryo, bone begins as hyaline cartilage and later ossifies. Fibrous cartilage has many collagen fibers and is found in the intervertebral discs and pubic symphysis. Elastic cartilage is springy, yellow, and elastic and is found in the internal support of the external ear and in the epiglottis.

Do chondrocytes make cartilage?

Chondrocytes (/ˈkɒndrəsaɪt, -droʊ-/, from Greek χόνδρος, chondros = cartilage + κύτος, kytos = cell) are the only cells found in healthy cartilage. They produce and maintain the cartilaginous matrix, which consists mainly of collagen and proteoglycans….

What’s the difference between a bone and a cartilage?

Bones are the hard, inelastic and a tough organ that forms part of the vertebral skeleton. Cartilage is a soft, elastic and flexible connective tissue that protects the bone from rubbing against each other. Bones are of two types: compact or spongy.

What are the different types of cartilage cells?

Cartilage is of three types: Hyaline cartilage, fibrocartilage and elastic cartilage. Bone cells are known as osteocytes. Cartilage cells are known as chondrocytes. Presence of blood vessels. The matrix is both organic and inorganic.

Why does injury to cartilage heal much more slowly than bone?

Chondrocytes rely on diffusion to obtain nutrients as, unlike bone, cartilage is avascular, meaning there are no vessels to carry blood to cartilage tissue. This lack of blood supply causes cartilage to heal very slowly compared with bone.

Where is elastic cartilage found in the human body?

In elastic cartilage the cells are closer together creating less intercellular space. Elastic cartilage is found in the external ear flaps and in parts of the larynx.
