3 Νοε 2023 · During embryonic development, hyaline cartilage serves as temporary cartilage models that are essential precursors to the formation of most of the axial and appendicular skeleton. This article will focus on important features of hyaline cartilage, namely its matrix, chondrocytes, and perichondrium.

31 Αυγ 2017 · Formed by the process of chondrogenesis, the resulting chondrocytes are capable of producing large amounts of collagenous extracellular matrix and ground substance, which together form cartilage itself. This article explains the structure, composition, formation and histology of cartilage.
17 Ιουλ 2023 · There are two main cell types in cartilage: Chondroblasts; Chondrocytes; The chondroblasts are found near the outer surface of the cartilage, under the perichondrium, and these secrete the extracellular matrix. As they do this, they become entrapped and mature into chondrocytes.
11 Ιαν 2024 · Cartilage tissue (hyaline cartilage) is initially formed from aggregated mesenchymal cells, which is later broken down and ossified. Both types of ossification play an essential role in the formation of long bones, while only endochondral ossification takes place in short bones.
Three types of cartilage are recognized based on differences in fiber composition: Hyaline cartilage - type II collagen. Elastic cartilage - elastic fibers and type II collagen. Fibrocartilage - type I and II collagens. Cartilage is avascular and its cells rely on diffusion for nutrients.
Cells. The extracellular matrix of cartilage is secreted by chondroblasts, (chondro = cartilage), which are found in the outer covering layer of cartilage. As the chondroblasts secrete matrix and fibres, they become trapped inside it, and mature into cells called chondrocytes. (See diagram opposite)
The main cell types in cartilage are chondrocytes, the ground substance is chondroitin sulfate, and the fibrous sheath is called perichondrium. There are three types of cartilage: hyaline, fibrous, and elastic cartilage. Hyaline cartilage is the most widespread type and resembles glass.
