What function is hyaline cartilage?

Hyaline cartilage provides mechanical support for the respiratory tree, nose, articular surfaces, and developing bones. Elastic cartilage has abundant elastic fibers in addition to collagen, making the matrix much more elastic than hyaline cartilage.

What is the structure and function of hyaline cartilage?

Hyaline cartilage is found in the synovial joints and assists the motion of joints. It is composed of chondrocytes and extracellular matrix. Chondrocytes plays a major role in the organization of extracellular matrix, which is responsible for the biomechanical properties of cartilage tissue.

What is hyaline cartilage also known as?

When hyaline cartilage is on the articular surfaces of bones (the surfaces at joints), it is called articular cartilage.

What is hyaline cartilage made of?

Hyaline cartilage, the most common type of cartilage, is composed of type II collagen and chondromucoprotein and often has a glassy appearance. Note the numerous chondrocytes in this image, each located within lacunae and surrounded by the cartilage they have produced.

What joints have hyaline cartilage?

Hyaline cartilage is the glass-like (hyaline) but translucent cartilage found on many joint surfaces. It is also most commonly found in the ribs, nose, larynx, and trachea….

What joints contain hyaline cartilage?

Hyaline cartilage is the most widespread and is the type that makes up the embryonic skeleton. It persists in human adults at the ends of bones in free-moving joints as articular cartilage, at the ends of the ribs, and in the nose, larynx, trachea, and bronchi.

Where is hyaline cartilage tissue?

Hyaline cartilage is the most widespread and is the type that makes up the embryonic skeleton. It persists in human adults at the ends of bones in free-moving joints as articular cartilage, at the ends of the ribs, and in the nose, larynx, trachea, and…

Why is hyaline cartilage glassy?

This type of cartilage has a glassy appearance when fresh, hence its name, as hyalos is greek for glassy. Hyaline cartilage has widely dispersed fine collagen fibres (type II), which strengthen it. The collagen fibres are hard to see in sections.

What type of cartilage is hyaline cartilage?

Hyaline cartilage is the glass-like (hyaline) but translucent cartilage found on many joint surfaces. It is also most commonly found in the ribs, nose, larynx, and trachea. Hyaline cartilage is pearl-grey in color, with a firm consistency and has a considerable amount of collagen.

How is hyaline cartilage formed?

In an embryo, hyaline cartilage makes up the first skeleton, then modifies as the embryo develops. This is by a process known as endochondral ossification. Hyaline cartilage consists of fine type II collagen fibers, chondrocytes (matrix producing cells), and the extracellular matrix (or ground substance).

How does hyaline cartilage differ from other cartilage?

Hyaline cartilage is easily distinguished from elastic and fibrocartilage because of the homogeneous (no fibers are visible) extracellular matrix (ECM) . Elastic cartilage (like hyaline cartilage) has chondrocytes located in lacunae and the tissue is surrounded by a perichondrium .

Why is hyaline cartilage different from elastic or fibrocartilage?

Does hyaline cartilage contain blood vessels?

Cartilage is classified in three types, elastic cartilage, hyaline cartilage and fibrocartilage, which differ in relative amounts of collagen and proteoglycan. Cartilage does not contain blood vessels (it is avascular) or nerves (it is aneural).

Does hyaline cartilage have collagen fibers?

Elastic cartilage refers to yellow cartilage, which contains elastin as the main protein component of the cartilage. The yellow color is due to the presence of elastin fibers. It also contains type II collagen fibers in the cartilage.

What type of cartilage is the most abundant?

Hyaline cartilage, the most abundant type of cartilage, plays a supportive role and assists in movement. Formed by the process of chondrogenesis, the resulting chondrocytes are capable of producing large amounts of collagenous extracellular matrix and ground substance, which together form cartilage itself.

What is the least common type of cartilage?

Cartilage. Elastic -This is the least common type of cartilage found in the body. It has a yellowish appearance due to elastic fibres of elastin molecules in the intercellular matrix. Elastic cartilage is not very “strong” by comparison to hyaline cartilage, but it is much more flexible and it also has some elasticity.
