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.
What are the 3 types of cartilage and their functions?
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.
Is hyaline cartilage elastic 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 hyaline 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.
What is an elastic cartilage?
Elastic cartilage is a structural cartilaginous tissue for non-load-bearing body parts, such as ears, nose, and epiglottis (Hutmacher et al., 2003). From: Nanocomposites for Musculoskeletal Tissue Regeneration, 2016.
What is a 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 are examples of elastic cartilage?
The external ear is an example of elastic cartilage, and the meniscus and annulus fibrosus of the IVD, which will be discussed later, are examples of fibrocartilaginous tissues. Articular cartilage is an example of hyaline cartilage, the most common type.
What type of cartilage is found in elastic cartilage?
Structure. Elastic cartilage is histologically similar to hyaline cartilage but contains many yellow elastic fibers lying in a solid matrix. These fibers form bundles that appear dark under a microscope.
What is the main difference between hyaline elastic and fibrocartilage?
The main difference between fibrocartilage and hyaline cartilage is that fibrocartilage is stiff and contains many collagen fibers whereas hyaline cartilage is a soft cartilage that contains fewer fibers.
What is elastic cartilage?
What are examples of hyaline cartilage?
Hyaline cartilage is found around the bones of free-moving joints. This is known as articular cartilage. Another example of hyaline cartilage is the tissue found in the walls of the respiratory tract. This includes the bronchi, the nose, the rings of the trachea, and the tips of the ribs.
What is an example of elastic cartilage?
The elastic cartilage is found in the outer ear, Eustachian tube and epiglottis.
Which is an example of hyaline cartilage?
What is the difference between fibrocartilage and elastic cartilage?
Fibrocartilage – is the strongest cartilage, and is found in the in intervertebral discs, joint capsules and ligaments. Elastic Cartilage – provides strength and shape maintenance, and can be found in the external ear, epiglottis and the larynx.
Where is hyaline cartilage found?
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.
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) .
What is the difference between hyaline elastic and fibrocartilage?
Hyaline cartilage contains fibers made primarily of type II collagen only. Fibrocartilage contains type II collagen but also contains abundant type I collagen. Elastic cartilage contains type II collagen and elastic fibers.
What is the hyaline 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.
What is elastic fibrocartilage?
Elastic cartilage, fibroelastic cartilage or yellow fibrocartilage is a type of cartilage present in the pinnae (auricles) of the ear giving it shape, provides shape for the lateral region of the external auditory meatus, medial part of the auditory canal Eustachian tube, corniculate and cuneiform laryneal cartilages.
How can you tell the difference between hyaline and elastic cartilage?
The key difference between elastic cartilage and hyaline cartilage is that elastic cartilage is yellowish in colour and is the least common type of cartilage while hyaline cartilage has a glassy appearance and is the most common type of cartilage.
What is the difference between hyaline cartilage elastic cartilage and fibrocartilage?
Elastic cartilage has a high concentration of elastin fibers arranged in an extracellular matrix structure, and unlike hyaline cartilage, it does not calcify for the formation of bones….Main Differences.
