BIO 210 Test #3 100% Solved CHAPTER 8 - Answer- JOINTS AND ARTICULAR MOVEMENTS joint - Answer- articulation; the junction of two or more bones structural classification of joints - Answer- focuses on the material binding the bones together and whether or not a joint cavity is present (fibrous, cartilaginous, and synovial joints) functional classification of joints - Answer- based on the amount of movement allowed at the joint (synarthroses, amphiarthroses, and diarthroses) synarthroses - Answer- immovable joints syn=together, arthro=joint amphiarthroses - Answer- slightly moveable joints amphi=on both sides, arthro=joint diarthroses - Answer- freely moveable joint dia=apart, arthro=joint fibrous joint - Answer- bones joined together by fibrous tissue; no joint cavity is present; connection made by hyaline cartilage or dense irregular connective tissue --TYPES-- -sutures -syndesmoses -gomphoses sutures - Answer- aka synostoses meaning "seams"; occur only between bones of the skull; exhibit interlocking edges filled with minimal amounts of very short connective tissue fibers continuous with the periosteum; synarthroses = immovable (ex. plated bones of skull) syndesmoses - Answer- (syndesmos = ligament) bones that are exclusively connected by ligaments, cords, or bands of fibrous tissue; move-ability related to length of tissue band; amphiarthroses = slightly moveable, ranges (ex. radial-ulnar articulations) gomphoses - Answer- peg-in-socket fibrous joint; only found in the articulation of a tooth with its bony alveolar socket; uses periodontal ligaments for attachment; synarthroses = immovable (ex. teeth) cartilaginous joints - Answer- articulating bones are united by cartilage; lack a joint cavity and are not highly moveable
