CARTILAGE. Hard connective tissue, next to bone and teeth Made up of cells, fibers and jell like matrix . FEATURES :- Translucent, firm, and elastic It can be compressible It can with stand considerable pressure, pull and torsion. CARTILAGE. STRUCTURE (HISTOLOGY) :-
Cartilage. Specialised Connective Tissue. Types. Hyaline (glassy) Elastic Fibrous. Hyaline Cartilage. Most common Nostrils, larynx, costal and joints Components Matrix Amorphous ground substance Fibres Collagen Jelly-like Cells Chondrocytes. Hyaline Cartilage. Chondrocytes
Cartilage. Dr. PARDEEP KUMAR. CARTILAGE It is a specialized form of connective tissue consists of cells, fibres & ground substance. The cells are embedded in the intercellular matrix Origin - Mesenchymal in origin. Cartilage. Embryo More prevalent than in adult
Cartilage. Functions of Cartilage Tissue. Specialized CT in which the firm consistency of the extracellular matrix allows the tissue to bear mechanical stresses without permanent distortion Supports soft tissues. Shock-absorbing because it is resilient.
CARTILAGE . Dr Iram Tassaduq. CARTILAGE . Cartilage is a type of connective tissue derived from mesenchyme, in which the ground substance is hardened and provides support. . CARTILAGE .
Cartilage. Functions:. ◘ Support soft tissues (nose, ear, trachea). ◘ Shock-absorbing and sliding areas for joints, facilitate bone movements. ◘ E ssential for the d evelopment and growth of long bones. Structure. Cells: chondrocytes Extracellular matrix. Structure. fiber
Cartilage. A non-vascular structural material found in various parts of the body. Forms most of the skeleton in infants. Replaced by bone through ossification during the maturing process. Temporary Cartilage – Cartilage which is naturally replaced by bone during ossification.
CARTILAGE. By Dr Iram Tassaduq. CARTILAGE. Is a specialized type of connective tissue. Form part of skeleton where flexibility is required Does not contain vessels or nerves. . COMPONENTS OF CARTILAGE. Consists of cells and extracellular components. Does not contain vessels or nerves.
