Joints and their classification
Joints (articulation or arthrosis) and their classification:
Joint is formed by the connective tissues to hold the bones together. Basically joints are the point of contact between either two bones or bones and cartilages or bones and teeth.
Classification of joints
a) Fibrous joints
b) Cartilaginous joints
c) Synovial joints
Bones of the joint are held very closely together with the help of dense irregular connective tissues, rich in collagen fibers. Synovial cavity (space between two articulating bones) is absent in such types of joints. Fibrous joints permit a very little or no movements.
The bones are held together by either hyaline cartilage or fibrocaritlage. Synovial cavity is absent.
Bones are united by dense irregular connective tissues of articular capsule and accessory ligaments. Synovial cavity is present. These are the freely movable joints due to presence of synovial cavity.
