Examples of hyaline cartilage in the following topics:
-
- Before this time, the embryonic skeleton consists entirely of fibrous membranes and hyaline cartilage.
- The development of bone from fibrous membranes is called intramembranous ossification; development from hyaline cartilage is called endochondral ossification.
- Endochondral ossification is the process of bone development from hyaline cartilage.
- In long bones, chondrocytes form a template of the hyaline cartilage diaphysis.
- Endochondral ossification is the process of bone development from hyaline cartilage.
-
- Cartilaginous joints are connected entirely by cartilage (fibrocartilage or hyaline).
- Where the connecting medium is hyaline cartilage, a cartilaginous joint is termed a synchondrosis or primary cartilaginous joint.
- In this example, the rib articulates with the sternum via the costal cartilage.
- The epiphyseal plate is a hyaline cartilage plate in the metaphysis at each end of a long bone.
- Section through occipitosphenoid synchondrosis of an infant, including the cartilage, perichrondrium, and periosteum.
-
- The periosteal cells proximal (closest) to the fracture gap develop into chondroblasts that form hyaline cartilage.
- The fibroblasts within the granulation tissue develop into chondroblasts that also form hyaline cartilage.
- Eventually, the fracture gap is bridged by the hyaline cartilage and woven bone, restoring some of its original strength.
- The next phase is the replacement of the hyaline cartilage and woven bone with lamellar bone.
- Substitution of the woven bone with lamellar bone precedes the substitution of the hyaline cartilage with lamellar bone.
-
- In the embryo, bones form first as hyaline cartilage before ossifying as development progresses.
- Hyaline cartilage is found on many joint surfaces.
- Elastic cartilage is histologically similar to hyaline cartilage but contains many yellow elastic fibers lying in a solid matrix.
- Images of microscopic views of the different types of cartilage: elastic, hyaline, and fibrous.
- Elastic cartilage has the most ECM; hyaline a middle amount; and fibrous cartilage has the least amount of ECM.
-
- A cartilage with few collagen and elastic fibers is hyaline cartilage.
- Hyaline cartilage is also found at the ends of long bones, reducing friction and cushioning the articulations of these bones.
- For example, hyaline cartilage found in movable joints, such as the knee and shoulder, often becomes damaged as a result of age or trauma.
- Damaged hyaline cartilage is replaced by fibrocartilage, resulting in "stiff" joints.
- Hyaline cartilage consists of a matrix with cells called chondrocytes (shown here) embedded in it.
-
- Cartilaginous joints are those in which the bones are connected by cartilage.
- In a synchondrosis, the bones are joined by hyaline cartilage.
- In symphyses, hyaline cartilage covers the end of the bone, but the connection between bones occurs through fibrocartilage.
- The ends of the bones are covered with articular cartilage, a hyaline cartilage.
-
- Cartilage is composed of specialized cells called chondroblasts and, unlike other connective tissues, cartilage does not contain blood vessels.
- Cartilage is classified in three types: 1) elastic cartilage, 2) hyaline cartilage, and 3) fibrocartilage, which differ in the relative amounts of these three main components.
- This is similar to hyaline cartilage but is more elastic in nature.
- It is a major part of the embryonic skeleton, the costal cartilages of the ribs, and the cartilage of the nose, trachea, and larynx.
- This is a blend of hyaline cartilage and dense regular connective tissue.
-
- The division
of cells within cartilage occurs very slowly.
- Therefore, growth in cartilage is
usually not based on an increase in size or mass of the cartilage itself.
- Remodeling of cartilage is predominantly affected by changes and rearrangements
of the collagen matrix, which responds to tensile and compressive forces
experienced by the cartilage.
- Damaged hyaline cartilage is usually replaced by fibrocartilage scar tissue.
- However, due to the extremely slow growth of cartilage and its avascular properties, regeneration and growth of cartilage post-injury is still very slow.
-
- Articular cartilage is a flexible material found between bones at movable joints.
- Following the initial chondrification that occurs during embryogenesis, cartilage growth consists mostly of the maturing of immature cartilage to a more mature state.
- The division of cells within cartilage occurs very slowly, and thus growth in cartilage is usually not based on an increase in size or mass of the cartilage itself.
- Articular cartilage is maintained by embedded chondrocytes that comprise only 1% of the cartilage volume, and remodeling of cartilage is predominantly affected by changes and rearrangements of the collagen matrix, which responds to tensile and compressive forces experienced by the cartilage.

-
- The diaphysis and both epiphyses of a long bone are separated by a growing zone of cartilage (the epiphyseal plate).
- This process involves replacing the hyaline cartilage, initially present at the epiphyseal region, with active osteoblasts that deposit bone structural proteins.
- Zone of reserve cartilage: This region is farthest from the marrow cavity and consists of hyaline cartilage that does not actively transform into bone.
