A junction between 2 or more bones/cartilages is called a JOINT. Joint permits mobility and stability. A human skeletal has approximately more than 200 bones that are connected by joints. Also, joints help to form cavities like cranial, thoracic, abdominal & pelvic cavities. There are more joints in the child than in an adult because with age some bones fuse. CLASSIFICATION OF JOINTS: 1] STRUCTURAL CLASSIFICATION 1.Fibrous Joints -The bones are joined by fibrous tissue and these are mostly immovable or slightly movable joints. 3 Subtypes:- a) Sutures -They are present only in the “skull”. In this type, bones are connected by connective tissue called a sutural ligament. Fusion of bony components occurs later in life leading to the formation of bony union. In infants, there is an anatomical feature in the skull comprising soft membranous gaps called “FONTANELLE”. Eg: Suture between frontal & parietal bone, temporoparietal suture b) Syndesmosis In this type, bones are connected di...
