Difference between Bone and Cartilage
Bones and cartilage differ by structure, types, and function. The main difference between bone and cartilage are listed below.
Bones Cartilage
Bones are the hard, inelastic and a tough organ that forms part of the vertebral skeleton. Cartilage is soft, elastic and flexible connective tissue that protects the bone from rubbing against each other.
Bones are of two types: compact or spongy. Cartilage is of three types: Hyaline cartilage, fibrocartilage, and elastic cartilage.
Bone cells are known as osteocytes. Cartilage cells are known as chondrocytes.
Presence of blood vessels. Absence of blood vessels.
The matrix is both organic and inorganic. The matrix is completely organic.
Has deposits of calcium salts. May or may not have deposition of calcium salts.
The bones have a rich blood supply. Lacks blood supply except in few cartilages.
Growth pattern of the bone is bidirectional. Growth pattern of the cartilage is unidirectional.
Presence of calcium phosphate in the matrix. Has no calcium phosphate in the matrix.
Haversian canal system is present. Haversian canal system is absent.
Volkmann canal is present. Volkmann canal is absent.
Protect the body from mechanical damage, provide a framework and shape for the body, helps in the movement of the body, store minerals, and produce both RBC – red blood cells and WBC – white blood cells. Supports the respiratory tract, acts as shock absorbers between weight-bearing bones, maintains the shape and flexibility of fleshy appendages and reduces friction at joints.
