Ans: Joints can be classified structural based on two criteria: 1) the presence or absence of a space between the articulating bones called a synovial cavity and 2) the type of connective tissue that binds the bones together. The structural types of joints include fibrous, cartilaginous and synovial. Difficulty: medium Feedback: 9.1 2. This type of joint is held together by a fibrous connective tissue. a. Fibrous joint b.
