12/2/21, 12:01 AM Lab 9 Assignment Lab 9 Assignment Due: 11:59pm on Monday, October 18, 2021 . Exercise 9 Review Sheet: Articulations Articulations, or joints, are the functional junctions between bones. They bind various parts of the skeletal system together, allow bone growth and development, permit parts of the skeleton to change shape, and, with the skeletal muscles, provide body movement. Articulations are classified according to functional and structural characteristics: 1. Functional classification (degree of movement) a. Synarthroses (singular = synarthrosis): joints where no movement occurs b. Amphiarthroses (singular = amphiarthrosis): joints that have limited movement c. Diarthroses (singular = diarthrosis): joints that are freely movable 2. Structural classification (type of articulation) a. Fibrous joints: articulating bones are held together by fibrous connective tissue. b. Cartilaginous joints: articulating bones are held together by cartilage. c. Synovial joints: a connective tissue capsule encloses a fluid-filled cavity between the articulating bones. Synarthroses and amphiarthroses can be either fibrous or cartilaginous joints. All diarthroses are synovial joints. To complete this Review Sheet, please complete the questions and activities below.
