What is the matrix composed of in elastic cartilage quizlet?
cartilage is a connective tissue consists of dense matrix of collagen fibers and elastic fibers embedded in a rubbery ground substance (hyaluronic acid, proteoglycans and small amount of several glycoproteins). The matrix is produced by cells called chondroblast, which become embedded in the matrix as chondrocytes.
What is the matrix of cartilage made up of?
The matrix of cartilage is made up of glycosaminoglycans, proteoglycans, collagen fibers and, sometimes, elastin.
Does elastic cartilage have territorial matrix?
The territorial matrix is the tissue surrounding chondrocytes (cells which produce cartilage) in cartilage. Chondrocytes are inactive cartilage cells, so they don’t make cartilage components.
What cell produces the cartilaginous matrix?
What cell produces the cartilaginous matrix? The mature cell in cartilage is a chondrocyte. It rests in a lacunae surrounded by matrix. A chondroblast is an immature cartilage cell which produces the cartilaginous matrix.
What type of cartilage makes up articular cartilage?
hyaline cartilage
Articular cartilage is hyaline cartilage and is 2 to 4 mm thick. Unlike most tissues, articular cartilage does not have blood vessels, nerves, or lymphatics. It is composed of a dense extracellular matrix (ECM) with a sparse distribution of highly specialized cells called chondrocytes.
How is the matrix of elastic cartilage and fibrocartilage different from the matrix of hyaline cartilage?
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.
Why is the territorial matrix of cartilage Basophilic?
Note that the cartilage matrix is relatively homogeneous and basophilic. This is due to the masking of the collagen fibers by the high concentration of the glycosaminoglycans in the ground substance. The matrix immediately surrounding the lacunae is more intensely basophilic. This zone is the territorial matrix.
Does elastic cartilage have elastic Fibres?
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.
How is Highland 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) . … Elastic cartilage (like hyaline cartilage) has chondrocytes located in lacunae and the tissue is surrounded by a perichondrium .
