| Bone | Cartilage |

Types: | Bones are classified into long, short, flat, irregular, sesamoid and sutural bones. | Types of cartilage include hyaline cartilage, fibrocartilage and elastic cartilage. |

Function: | Bones protect the body against mechanical damage, assisting in the movement of the body, providing a framework and shape for the body, storing minerals and producing red blood and white blood cells. | The main functions of cartilage tissue include reducing friction at the joints, supporting tracheal and bronchial tubes, acting as shock absorbers between vertebrae, and maintaining the shape and flexibility of ear, nose and so on. |

Structure: | Bone or osseous tissue is made up of osteoblasts (progenitor cells), osteocytes (mature bone cells), and osteoclasts (large cells that breakdown bone tissue for growth and repair), and bone lining cells (that regulate the movement of calcium) | Cartilage comprises of chondroblasts, which are precursor cells, chondrocytes, and dense matrix comprising of collagen and elastic fibres, in which the maturechondrocyte cells are embedded. |

Diseases /Disorders: | Disorders of the bone consist of osteoporosis, osteosarcoma, osteomyelitis and osteogenesis imperfecta which is a geneticdisorder and other disorders. | Diseases of the cartilage include osteoarthritis, achondroplasia, costochondritis, and other chondrodystrophies. |

Where found in the body: | Bones make up the endoskeleton of vertebrates. | Cartilage is a much softer, more pliable component that is mostly found in between joints of bones. |

Membrane: | periostium | pericondrium |

Cartilage

Cartilage is a flexible but strong supportive connective tissue.  Unlike bone and all other connective tissue types, cartilage is avascular,  lacking blood vessels.  For this reason alone, cartilage does not possess the regenerative capacity of bone or the other connective tissue types.  Remember, nutrient delivery is essential for tissue...
