Anatomy and physiology Chapter 8 Exam questions The amount of movement permitted by a particular joint is the basis for the functional classification of joints. - Correct Answer True All joints permit some degree of movement, even if very slight. - Correct Answer False Articulations permitting only slight degrees of movement are ________. - Correct Answer amphiarthroses Synarthrotic joints ________. - Correct Answer permit essentially no movement The structural classification of joints is based on the composition of the binding material and the presence or absence of a joint cavity - Correct Answer True A fibrous joint that is a peg-in-socket is called a ________ joint. - Correct Answer gomphosis On the basis of structural classification, which joint is fibrous connective tissue? - Correct Answer syndesmosis Fibrous joints are classified as ________. - Correct Answer sutures, syndesmoses, and gomphoses An example of an interosseus fibrous joint is ________. - Correct Answer the radius and ulna along its length The joint between the frontal and parietal bones is called a ________ joint. - Correct Answer suture Using the functional classification, a freely movable joint would be called a ________ joint. - Correct Answer diarthrosis Symphyses are synarthrotic joints designed for strength with flexibility. - Correct Answer False Articular cartilage found at the ends of the long bones serves to ________. - Correct Answer provide a smooth surface at the ends of synovial joints A joint united by dense fibrocartilaginous tissue that usually permits a slight degree of movement is a ________. - Correct Answer symphysis ________ are cartilaginous joints - Correct Answer Synchondroses 1 / 2
In symphysis joints the articular surfaces of the bones are covered with ________. - Correct Answer hyaline cartilage Synovial fluid is present in joint cavities of freely movable joints. Which of the following statements is true about this fluid? - Correct Answer It contains hyaluronic acid Which of the following statements defines synchondroses? - Correct Answer cartilaginous joints where hyaline cartilage unites the ends of bones Hinge joints permit movement in only two planes. - Correct Answer False Synovial fluid is a viscous material that is derived by filtration from blood. - Correct Answer True The articular surfaces of synovial joints play a minimal role in joint stability. - Correct Answer True The major role of ligaments at synovial joints is to help direct movement and restrict undesirable movement. - Correct Answer True The only movement allowed between the first two cervical vertebrae is flexion. - Correct Answer False Movement at the hip joint does not have as wide a range of motion as at the shoulder joint. - Correct Answer True A movement of the forearm in which the palm of the hand is turned from posterior to anterior is supination. - Correct Answer True The wrist joint can exhibit adduction and eversion movements. - Correct Answer False Cruciate ligaments are important ligaments that stabilize all ball-and-socket joints. - Correct Answer False Flexion of the ankle so that the superior aspect of the foot approaches the shin is called dorsiflexion. - Correct Answer True The gripping of the trochlea by the trochlear notch constitutes the "hinge" for the elbow joint. - Correct Answer True The ligamentum teres represents a very important stabilizing ligament for the hip joint. - Correct Answer False Synovial fluid contains phagocytic cells that protect the cavity from invasion by microbes or other debris. - Correct Answer True
