Then save the document as ‘Lastname_JointsWorksheet’ and submit within your course module. 1. In what two ways can joints be classified? What are the three classifications of each type? (1 pt) a. Structurally = fibrous joints, cartilaginous joints, and synovial joints b. Functionally = immovable (synarthrotic), slightly movable (amphiarthrotic), and freely movable (diarthrotic) 2. Fibrous joints are either sutures or syndesmoses. What is the difference between the two? Give examples of each type. (2 pts) a. Sutures- Only between the flat bones of the skull; where the parietal and occipital bone meet and where the parietal and frontal bone meet b. Syndesmoses- Bones bound by a sheet or bundle of dense connective tissue; between the tibia and fibula and between the radius and ulna
