Biology 325 Human anatomy and physiology Fall 2004 Articulations Name Articulations pre lab exercise due at beginning of your lab session Matching a fibrous joints b cartilaginous joints c synovial joints 1 2 3 4 5 6 7 8 9 exhibit a joint cavity types are sutures and syndesmoses bones connected by collagen fibers types include synchondroses and symphyses are all diarthrotic many are amphiarthrotic bones connected by disc of hyaline cartilage or fibrocartilage shoulder hip jaw and elbow joints nearly all are synarthrotic Multiple choice 1 a b c d The cruciate ligaments of the knee tend to run parallel to one another are also called collateral ligaments prevent hyperextension of the knee assist in defining the range of motion of the leg 2 The ligaments that protect the alignment of the femoral and tibial condyles and limit the movement of the femur anteriorly and posteriorly are called a cruciate ligaments b patellar ligaments c anterior ligaments d tibial collateral ligaments 3 a b c d The shoulder joint is a good example of a synovial joint nonaxial uniaxial biaxial multiaxial 4 a b c d Compared to the shoulder displacement of the hip joints are common due to the weight bearing the hip endures rare because of ligament reinforcement common in overweight individuals rare because the rotator cuff stabilizes the hip joint Biology 325 Human anatomy and physiology 5 a b c d Tendon sheaths act as friction reducing structures are lined with dense irregular connective tissue form channels for tendons help anchor the tendon to the muscle 6 a b c d The elbow joint is a plane joint picot joint condyloid joint hinge joint 7 a b c d When a ballerina points the toes it is known as circumduction plantar flexion dorsiflexion extension 8 a b c d e A joint that does not permit movement is called a synarthrosis a hinge joint a synovial joint a diarthrosis an amphiarthrosis 9 a b c d e Which of the following permits slight movement gomphosis suture syndesmosis synchondrosis synostosis 10 A joint that permits free movement in only one direction is a a monoaxial joint b biaxial joint c triaxial joint d syndesmosis e suture 11 A cartilaginous joint that does not permit movement is a a syndesmosis b synovial joint c synostosis d synchondrosis e none of the above Fall 2004 Articulations Biology 325 Human anatomy and physiology Fall 2004 Articulations 12 A joint that permits free movement in only one direction is a a monaxial joint b biaxial joint c triaxial joint d syndesmosis e suture 13 Synovial fluid in a joint cavity serves which of the following functions a shock absorption b chondrocyte nourishment c lubrication d all of the above e none of the above 14 The function of a bursa is to a reduce friction between a bone and a tendon b absorb shock c smooth the surface outline of a joint d replace synovial fluid lost in an injured joint e A and B from above 15 All of the following are true of the movement capabilities of joints except a great stability decreases mobility b they may be directed or restricted to certain directions by the shapes of articulating surfaces c they may be modified by the presence of accessory ligaments and collagen fibers of the joint capsule d the strength of the joint is determined by the strength of the muscles which attach to it and its joint capsule e no exceptions all of the above are true 16 A joint in which the articular surfaces can slide in any direction is called a uniaxial b biaxial c multiaxial d monaxial e none of the above 17 Examples of angular motion include all of the following except a flexion b adduction c extension d rotation e no exceptions all of the above are included Biology 325 Human anatomy and physiology Fall 2004 Articulations 18 A type of movement in the sagittal plane which reduces the angle between the articulating elements is a extension b rotation c gliding d flexion e adduction 19 A special type of angular motion is a flexion b circumduction c abduction d elevation e adduction 20 Between the articular facets of adjacent vertebrae a relatively flat articular surfaces slide across one another b the gliding joints are either nonaxial or multiaxial c hinge diarthroses allow both flexion and extension d Both A and B e none of the above 21 Joints between the vertebrae include a pivot joints b gliding joints c ellipsoidal joints d hinge joints e both A and C 22 Which action does not occur along the vertebral column a anterior flexion b extension c protraction d lateral flexion e rotation 23 Which of the following is true regarding the shoulder joint a It permits the greatest range of movement of any joint in the body b It is one of the least frequently dislocated joints of the body c It is primarily a hinge joint d It has the greatest stability of any joint in the body e none of the above 24 All of the following factors contribute to the integrity and normal functioning of the shoulder joint except a the glenoid labrum b tendons c ligaments d the coronoid process e no exceptions all of the above contribute Biology 325 Human anatomy and physiology Fall 2004 Articulations 25 Actions permitted by the distal radioulnar articulation include a elevation and flexion b pronation and supination c depression and protrusion d rotation e all of the above 26 The carpometacarpal joint of the thumb is a a gliding joint b hinge joint c saddle joint d symphyseal joint e none of the above 27 Interphalangeal joints are a ellipsoidal joints b hinge joints c gliding joints d ball and socket joints e none of the above 28 All of the joints of the hand are a gliding joints b synchondroses c diarthroses d ellipsoidal joints e none of the above 29 All of the following are ligaments that stabilize the hip joint and reinforce the articular capsule except a the iliofemoral ligament b the pubofemoral ligament c the ischiofemoral ligament d the transverse acetabular ligament e the ligamentum teres 30 Which of the ligaments of the knee is responsible for limiting the anterior posterior movement of the femur and maintaining the alignment of the femoral and tibial condyles a anterior and posterior cruciate
