When hyaline cartilage is on the articular surfaces of bones (the surfaces at joints), it is called articular cartilage. Articular cartilage functions as a shock absorber and also reduces friction between bones where they meet at joints.
What is a articular 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.
What is hyaline cartilage and where is it located?
characteristics. 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…
Why is hyaline 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.
What is the difference between hyaline and articular cartilage?
Articular cartilage is a type of hyaline cartilage. It is different from usual hyaline cartilage as it has flattened chondrocytes near the surface. In humans, it is 2 to 4 mm thick. It does not have blood vessels, nerves, or lymphatics.
What is the function of hyaline cartilage tissue?
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 the difference between articular cartilage and fibrocartilage?
Cartilages are a type of connective tissue that is made up of chondrocytes and an extracellular matrix. 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 the difference of articular cartilage and epiphyseal cartilage?
A region of hyaline cartilage remains over the surface of the epiphysis as the articular cartilage and another area of cartilage remains between the epiphysis and diaphysis. This is the epiphyseal plate or growth region.
What is the function of hyaline cartilage?
Articular Cartilage Where bone ends meet to form a joint, they are covered by hyaline cartilage. This cartilage appears bluish white and glistening in a normal healthy joint. Its primary function is to provide some cushioning and minimize friction between the bone ends.
What type of cartilage is hyaline?
Hyaline cartilage is the glass-like (hyaline) but translucent cartilage found on many joint surfaces. It is also most commonly found in the ribs, nose, larynx, and trachea. Hyaline cartilage is pearl-grey in color, with a firm consistency and has a considerable amount of collagen.
What is the difference between fibrocartilage and hyaline cartilage?
Fibrocartilage is the strongest type of cartilage composed of numerous collagen fibres. In contrast, hyaline cartilage is the weakest type of cartilage composed of fewer collagen fibres. Thus, this is the key difference between fibrocartilage and hyaline cartilage.
What makes 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) . Elastic cartilage (like hyaline cartilage) has chondrocytes located in lacunae and the tissue is surrounded by a perichondrium .
What is hyaline cartilage 400x?
Hyaline cartilage 400X Cartilage consists of cells embedded in a matrix (mat) of fibers and ground substance. The cells are called chondrocytes (ch) and the spaces in the cartilage in which they are found are called lacunae. Hyaline cartilage has very few fibers in its matrix, so the matrix usually looks smooth.
What are the histologic characteristics of hyaline cartilage?
Hyaline cartilage histology 1 Matrix. The extracellular matrix (ECM) of hyaline cartilage is homogeneous and glassy, rich in in type II collagen, proteoglycans such as aggrecan, and structural glycoproteins such as chondronectin. 2 Chondrocytes. Chondrocytes occupy relatively little of the hyaline cartilage mass. 3 Perichondrium.
Are collagen fibrils visible in hyaline cartilage matrix?
Collagen fibrils are not visible in hyaline cartilage matrix. 1000x Isogenous groups and interstitial growth results when chondrocytes divide and produce extracellular matrix. Territorial matrix lies immediately around each isogenous group and is high in glycosaminoglycans.
What is the terterritorial matrix in cartilage?
Territorial matrix lies immediately around each isogenous group and is high in glycosaminoglycans. Therefore, this matrix stains more intensely than matrix farther from an isogenous group, the interterritorial matrix. Collagen fibrils are not visible in hyaline cartilage matrix. 1000x
