what is the difference between bone and cartilages?

Answer 1

Cartilage is a type of dense connective tissue. It is composed of collagenous fibers and/or elastin fibers, and cells called chondrocytes, all of which are embedded in a firm gel-like ground substance called the matrix. Cartilage is avascular (contains no blood vessels) and nutrients are diffused through the matrix. Cartilage serves several functions, including providing a framework upon which bone deposition can begin and supplying smooth surfaces for the movement of articulating bones. Cartilage is found in many places in the body including the joints, the rib cage, the ear, the nose, the bronchial tubes and between intervertebral discs. There are three main types of cartilage: hyaline, elastic and fibrocartilage.

Bones are rigid organs that form part of the endoskeleton of vertebrates. Bones function to move, support, and protect the body, produce red and white blood cells and store minerals. Bones come in a variety of shapes and have a complex internal and external structure, allowing them to be lightweight yet strong and hard, while fulfilling their many other functions. One of the types of tissues that makes up bones is the mineralized osseous tissue, also called bone tissue, that gives bones their rigidity and honeycomb-like three-dimensional internal structure. Other tissue types found in bones include marrow, the periosteum, nerves, blood vessels and cartilage.
