What is the function and location 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 are the main functions of cartilage?
Hyaline, or articular, cartilage covers the ends of bones to create a low-friction environment and cushion at the joint surface. When cartilage in the joint is healthy, it effectively allows fluid bending/straightening motions and protects the joint against weight-bearing stresses.
What are the 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 the function of the elastic cartilage?
Elastic cartilage has abundant elastic fibers in addition to collagen, making the matrix much more elastic than hyaline cartilage. Elastic cartilage supports structures subjected to frequent deformation, including the larynx, epiglottis, and external ear.
What are the 3 types of cartilage and their functions?
Cartilage: The 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.
What is the function of lacuna in hyaline cartilage?
In cartilage, the lacuna not only encases the chondrocyte it also serves to provide nutrients required for their survival. Cartilage is an avascular structure, and lacuna containing extracellular matrix serves to provide the essential elements for the survival of the chondrocytes.
What is the function of elastic cartilage connective tissue?
Elastic cartilage provides strength, and elasticity, and maintains the shape of certain structure such as the external ear.
What is the difference between elastic 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.
Where is 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…
What is 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.
What are the main functions of the cartilage tissue?
The most important functions of cartilage include: Cartilage gives shape, support, and structure to other body tissues. It also helps to cushion joints. Cartilage also smoothens the bone surfaces at the joints. It is essential for the development and growth of long bones.
What are characteristics of hyaline cartilage?
Hyaline cartilage: This type of cartilage has very thin fibers having same refractive index as the matrix of the cartilage and thus these fibers are not seen. Hyaline cartilage is the articular cartilage of long bones, sternum, ribs etc. Its color is bluish white and it is flexible.
What does the hyaline cartilage do?
Hyaline cartilage, like elastic cartilage, is usually lined with perichardium, a layer of irregular connective tissue that aids in the growth and repair of cartilage. All types of cartilage gain most of their physical properties from the extracellular matrix, the material surrounding the cells, than from the cells themselves.
How is hyaline cartilage different from elastic or fibrocartilage?
Hyaline cartilage is easily distinguished from elastic and fibrocartilage because of the homogeneous (no fibers are visible) extracellular matrix (ECM). The darker staining matrix immediately surrounding the capsule is called territorial matrix, while the matrix that occupies the majority of space between chondrocytes is interterritorial matrix.
