Cartilage is a resilient and smooth elastic tissue, a rubber-like padding that covers and protects the ends of long bones at the joints, and is a structural component of the rib cage, the ear, the nose, the bronchial tubes, the intervertebral discs, and many other body components. It is not as hard and rigid as bone, but it is much stiffer and much less flexible than muscle.
Because of its rigidity, cartilage often serves the purpose of holding tubes open in the body. Examples include the rings of the trachea, such as the cricoid cartilage and carina.
Cartilage is composed of specialized cells called chondrocytes that produce a large amount of collagenous extracellular matrix, abundant ground substance that is rich in proteoglycan and elastin fibers. Cartilage is classified in three types, elastic cartilage, hyaline cartilage and fibrocartilage, which differ in relative amounts of collagen and proteoglycan.

➧Types 0f Skeletal Tissue are:-▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃⤵
➊❫ Cartilage:- ▬▬▬▬▬▬▬▬☟
◉ Its nature is film but elastic.
◉ Herversian system is absent.
◉ Blood supply is limited to perichondrium.
◉ Mineral matter is deposited only in calcified cartilage.
◉ Chondrocytes cells occurs in groups of 2 or 4.
❱ It's Functions are:-═══════════════☟
①❭ It support the whole skeleton of body.
②❭ Intervertebral disc of cartilage absorb Shock.
③❭ It also act as a cushion against stress.
④❭ It prevents wear and tear.
❷❫ Bone:- ▬▬▬▬▬▬▬▬☟
◉ Its nature is firm & brittle.
◉ Haversian system is present.
◉ Blood is supplied to the inner region of the bone.
◉ Mineral matter is deposited in the matrix in the form of carbonate & phosphate of calcium.
◉ 0steocytes secure singly & are arranged in lamellae.
❱ It's Functions are:-═══════════════☟
①❭ It support the framework & protect internal organs.
②❭ It helps in locomotion.
③❭ It provide surface for the attachment of muscles.
④❭ It is the Reservoir of calcium & phosphorus.
