Q

Specialised connective tissue:

Cartilage is avascular and can be divided into 3 subgroups
H- (smooth, glassy appearance, tightly packed collagen fibres, found in the - tip)
E- ( flexible, collagen and elastic fibres ,light weight support found in the outer -)
F- (dense and tough, strongest collagen fibres, separates -)
