Difference between Hyaline Cartilage and Elastic 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.

How is hyaline cartilage different from elastic 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 .

What is the difference between the 3 types of cartilage?

There are three different types of cartilage: elastic (A), hyaline (B), and fibrous (C). ... Elastic cartilage is found in the external ear flaps and in parts of the larynx. Hyaline cartilage has fewer cells than elastic cartilage; there is more intercellular space.

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.

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 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.

Which is strongest cartilage?

Fibrous cartilage is the strongest kind of cartilage, because it has alternating layers of hyaline cartilage matrix and thick layers of dense collagen fibres oriented in the direction of functional stresses.

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 disease affects cartilage?

There are several inflammatory rheumatic diseases that lead to arthritis and can severely damage cartilage tissue. These include rheumatoid arthritis, juvenile idiopathic arthritis, gout, systemic lupus erythematosus, and seronegative spondyloarthropathies.

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 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 is a 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.
