Cartilage is a connective tissue consisting of a dense matrix of collagen fibres and elastic fibres embedded in a rubbery ground substance. The matrix is produced by cells called chondroblasts, which become embedded in the matrix as chondrocytes. That is, mature cartilage cells are called chondrocytes

Skeletal Tissue➫ A specialized contractile tissue found in animals which functions to move an organism's body.
➧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.
