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

Answer:

                  Common features of connective tissue are (i)Connective tissue is the most abundant and widely distributed tissue of the body. Itconnect with tissue with organs and also provides support to various body structures inanimals. (ii) Connects tissue is developed from the embryonic mesoderm. (iii) Three components are majorly present in the connective tissue matrix, cells and fibers. (iv) The extracellular matrix has nearly amorphous ground substance made ofglycoproteins with associated monopoly saccharides. This ground substance may beliquid, gel or solid. (v) The tissue has good amount of regenerative ability, (vi) Functions of connective tissue include storage of energy, protection of organs andbody's structural integrity. Differences between Bone and Cartilage

	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 of fleshy 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 (precursor cells), chondrocytes and dense matrix of collagen and elastic fibres in which the mature chondrocytes are embedded, cartilage is vascular.

 

	Bone	Cartilage
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).
