Write down the common features of the connective tissue. On the basis of structure and function. Differentiate between bones and cartilages.

Bone |
Cartilage |
Type |
Bones are either compact or spongy. Bones are classified into long, short, flat, irregular sesamoid and structural bones. |
Hyaline cartilage,fibro Cartilage and elastic cartilage |
Function |
Protect the body against the mechanical damage, assist in the movement of the body, provide a framework and shape for the body, store minerals and produce red blood and white blood cells. |
Reduces friction at joints, supports the respiratory tract, acting as shock absorbers between weight bearing bones and maintaining the shape and flexibility offleshy appendages. |
Structure |
Bones are made up of mostly of osteoblasts (progenitor cells), osteocyte (mature bone Cell) and osteoclasts (large cells, that breakdown bone tissue for growth and repair). A bone is highly vascularised. |
Cartilages comprise chondroblasts (precursorcells), chondrocytes and dense matrix of collagen and elastic fibres in which the mature chondracytes are embedded, cartilage is vascular. |
Location |
Bones make up the majority of the axial and appendicular skeleton. |
Cartilage is much softer, more pliable component that is mostly found in between joints of bones (articular cartilage). |
Fibrous covering |
Periosteum is rich in sensory nerve endings. |
Perichondrium (but does not surround articular cartilage). |
