Cartilage is type of dense connective tissue. Cartilage is composed of cells called chondrocytes which are dispersed in a firm gel-like ground substance, called the matrix.

 


Cartilage is a type of dense connective tissue. It is composed of collagen fibers and/or elastin fibers, and can supply smooth surfaces for the movement of articulating bones.

cartilage is more flexible and compressible than bone and often serves as an early skeletal framework, becoming mineralised as the animal ages.

The costal cartilages (Fig. 115) are bars of hyaline cartilage which serve to prolong the ribs forward and contribute very materially to the elasticity of the walls of the thorax.

Degradation of the cartilage proteoglycan, aggrecan, is an essential aspect of normal growth and development, and of joint pathology.

Bone. The matrix of bone contains collagen fibers and mineral deposits. The most abundant mineral is calcium phosphate, although magnesium, carbonate, and fluoride ions are also present. [More on bone] ...

Cartilage and bone are "rigid" connective tissues. Cartilage, shown in Figure 7, has structural proteins deposited in the matrix between cells. Cartilage is the softer of the two "rigid" connective tissues.

cartilage Type of connective tissue in which cells are located within lacunae and are separated by a semisolid matrix. Provides a site for muscle attachment, aids in movement of joints, and provides support.

(2) Fish with cartilage: In our opinion, though not as advanced as fish with real bones, fish with cartilage are the coolest fish out there. Cartilaginous fish include species of sharks, rays, and skates.

[Gr. chondrion - cartilage; Gr. kytos - a hollow vessel]. A mature chondroblast located in a lacunae and surrounded by a matrix. These cells make up the cellular component of cartilage.

Ehlers Danlos Syndrome connective tissue condition including problems with tendons, ligaments, skin, bones, cartilage, and membranes surrounding blood vessels and nerves. Symptoms include joint laxity, elastic skin, dislocations.

The more specialized connective tissues are cartilage, bone, adipose (fat) tissue and blood. We have cartilage in our noses and ears as adults but as an embryo and fetus we had cartilage in place of the bones that eventually replaced it.

The perichondrium, a connective tissue, forms around the cartilage and begins forming compact bone while the above changes are occurring. Blood vessels form and grow into the perichondrium, transporting stem cells into the interior.

Their skeleton is composed of entirely cartilage. The Class includes the sharks, rays and skates (subclass Elasmobranchii) and the ratfish (subclass Holocephali). The earliest taxon which has both MHC class I and class II genes.

epiglottis
A thin flexible structure, made of cartilage with a leaf-like shape, which guards the entrance to the larynx (the glottis) and prevents food material from entering the trachea during swallowing.

Vertebrates have a skeleton of bone or cartilage; arthropods have one made of chitin; while many other invertebrates use a hydrostatic skeleton, which is merely an incompressible fluid-filled region of their body.

It can be used to make mesenchymal tissues, which are muscle cartilage, bone tendons, and fat.

Proteoglycans Proteins containing one or more covalently linked glycosaminoglycan chains; cartilage proteoglycan contains keratan sulfate and chondroitin chains linked to a polypeptide backbone.
