Fixed joints are also called as?
Synarthrosis joint or fixed joint or immovable joint - these joints do not allow any movement because the bones are firmly fixed together by strong fibres. These joints in the skull are called sutures. The attachment of tooth with socket in jaw is example.
B. Amphiarthroses joint or slightly movable joint or cartilaginous joint or imperfect joint - these joints, the two bones are joined together with the help of a disc or pad of white fibrous cartilage. The disc of cartilage restricts the movement in these joints due to which these joints show limited or slight movement. The movement in these joints are only possible because of compression of the pads of cartilage present on the articulated or ends of the bone taking part in the joints. Examples are in sternum-ribs, pubic symphysis.
C. Diarthrosis joint or synovial joint or free movable joint - these are freely movable joint which allow movement in one or more directions. Examples are shoulder joint, hip joint, elbow joint.
