Difference Between Elastic Cartilage and Hyaline Cartilage

Hyaline cartilage is a translucent white type of cartilage present in areas of the body such as the joints. The main difference between this type of cartilage and elastic cartilage is that elastic cartilage contains many elastic fibers, whilst hyaline cartilage contains a matrix of mainly collagen fibers.

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

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).

What is the difference between hyaline and fibrocartilage?

Fibrocartilage contains a lot of collagen fibers in the matrix. But, hyaline cartilage contains fewer collagen fibers in the matrix. ... The main difference between fibrocartilage and hyaline cartilage is the density of collagen fibers in each type of cartilage.

What do hyaline cartilage and elastic cartilage have in common?

Both hyaline and elastic cartilages are made of special cells called chondroblasts (called chondrocytes when cells become old). These cells secrete extracellular matrix: which is made of collagen and peptidoglycan. Both hyaline and elastic cartilagenous tissues are surrounded by perichondrium, a layer of fibroblasts.

Is hyaline cartilage elastic?

It contains cartilage tissue and white fibrous tissue. Also, it is the only type of cartilage that has both type I and type II collagen. It is flexible, tough, and elastic.

Which is strongest cartilage?

You can find elastic cartilage in your ears and your larynx. Fibrocartilage contains even more collagen fibers than hyaline cartilage. It's the most rigid type of cartilage and can be found in intervertebral discs in the spine. It's also the strongest type of cartilage.

What is an example of hyaline cartilage?

Hyaline cartilage is found in trachea, larynx and bronchi, limb bones (called hyaline cap), sternum, in the hyoid apparatus nasal septum, ribs (sternal parts) larynx (cricoid, thyroid), and nasal cartilage (nasal septum). It is the weakest among the four types of cartilage.

What is the function of 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.

How do you identify hyaline cartilage?

Hyaline cartilage

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

What is hyaline cartilage?

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 heals faster bone or cartilage?

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.

What are characteristics of hyaline cartilage?

Hyaline cartilage is pearl-grey in color, with a firm consistency and has a considerable amount of collagen. It contains no nerves or blood vessels, and its structure is relatively simple.

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. 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.
