Vidyadip · Accepted Answer

Common features of connective tissue are:

Connective tissue is the most abundant and widely distributed tissue of the body. It connects tissues organs and also provides support to various body parts.
Connective tissue is developed from the embryonic mesoderm.
Three components are majority present in the connective tissue: matrix, cells and fibres.
The extracellular matrix has nearly amorphous ground substance made of glycoprotein’s with associated muco-polysaccharides. This ground substance may be liquid, gel or solid.
The tissue has good amount of regenerative ability.

Differences between bone and cartilage are:

	Bone	Cartilage
i.	It is the hardest tissuse in the body.	It is the soft skeletal tissue.
ii.	Matrix contains protein osssin.	Core protein of matrix is aggrecan.
iii.	Growth of bone is bidirectional.	Growth of cartilage is unidirectional.
iv.	Bones are either compate or spongy. Bones are into long, short, flat, irregular and structural bones.	Cartilage is of three types. Hyaline cartilage fibro cartilage and elastic cartilage.
v.	Protect the body against the mechanical damage, assist in the movement of the body, provide a framework and shape to the body, store minerelas and blood and white blood cells.	Reduces friction at joints, supports the tract, acts as shock absorber bones the shape and flexbility of flexibility of fleshy appensadge.
vi.	Bones comprise of costeoblasts and osteoclass. A bone is highly vascularised.	Cartilages comprise chondroblasts chondrocytes and collagen and embedded, cartilage is not much vascular.
vii.	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.
