All synovial joints have a joint cavity filled with synovial fluid that is the site at which the bones of the joint articulate with each other. a. condylar The calcium allows the myosin heads to latch on to the actin filaments and the muscle contraction occurs. Joint fluid is a transudate of plasma that is actively secreted by synovial cells. Which of the following is not a true synovial joint? A it covers a bone b. fibrocartilage C floating ribs B the ribs articulate with the thoracic vertebrae c. one A band to the next A band Direct support for a synovial joint is provided by ligaments that strongly unite the bones of the joint and serve to resist excessive or abnormal movements. The glenohumeral joint is more mobile, making it less stable. What are the possible values for m\mathbf{m}_{\ell}m for a) The articulating ends of the bones in a synovial joint are covered by articular cartilage. B PTH increases the reabsorption of calcium from bones These joints allow the bones to slide or rotate against each other, but the range of motion is usually slight and tightly limited by ligaments or surrounding bones. The knuckle (metacarpophalangeal) joints of the hand between the distal end of a metacarpal bone and the proximal phalanx are condyloid joints. 97) ___D___ A) the clavicle and the scapula at the distal ends B) between the humerus and the glenoid . D none of these, The paranasal sinuses open into the The articular cartilage has no nerve supply. Which joints are correctly matched? b. circumduction The articulating surfaces of the bones at a synovial joint are not bound to each other by connective tissue or cartilage, which allows the bones to move freely against each other. a. Endomysium a. Immovable joints are called amphiarthroses. A sphenoid A subtendinous bursa is found between a tendon and a bone. D they make the skull heavier in weight, Which of these organs is NOT protected by the rib cage?

Find the reluctance of a magnetic circuit if a magnetic flux =4.2104Wb\phi=4.2 \times 10^{-4} \mathrm{~Wb}=4.2104Wb is established by an impressed mmf of 400 A-turns. A) The greater tubercle of the humerus articulates at the coracoid process of the scapula. How should the nurse respond? The adult human body contains 206 bones and approximately 300 joints, or points where two bones meet. What is the most common cause of hip disability? d. the hip joint, The cruciate ligaments of the knee ________. b. Muscles obtain their energy through anaerobic respiration of glucose; this is beneficial because anaerobic repsiration can generate energy quickly c. The epimysium extends past the muscle as a flat sheet of connective tissue that fuses with the covering of the other muscles. Diarthroses are freely movable articulations. The cells of this membrane secrete synovial fluid (synovia = a thick fluid), a thick, slimy fluid that provides lubrication to further reduce friction between the bones of the joint. True or False: The gripping of the trochlea by the trochlear notch constitutes the "hinge" for the elbow joint. b. attach tendons True or False: The most important factor in joint stability is the depth of the articular surface. Which type of synovial joint offers the widest range of movement? c. pronation c.

Primary cartilaginous joints: These cartilaginous joints are composed entirely of . b. the additional joint present doubles the range of motion This allows the two bones to fit together like a rider sitting on a saddle. It is a connective tissue sac that surrounds a muscle tendon at places where the tendon crosses a joint. In contrast, the deep socket of the acetabulum and the strong supporting ligaments of the hip joint serve to constrain movements of the femur, reflecting the need for stability and weight-bearing ability at the hip. Which of the following is true of synovial fluid? d. biaxial, When you bring any of your fingers in contact with your thumb, this movement is called __________. b. d. menisci, An individual with a "double-jointed" thumb can pull it back towards the wrist much farther than normal. a. synovial fluid A synovial joint, also known as a diarthrosis, is the most common and most movable type of joint in a mammal's body. At a plane joint (gliding joint), the articulating surfaces of the bones are flat or slightly curved and of approximately the same size, which allows the bones to slide against each other (see Figure 9.4.3d). Pivot and hinge joints are functionally classified as uniaxial joints. The calcium binds with troponin on the actin filaments, which permits the myosin heads to latch on and muscle contraction occurs c. Type sof tendons B the secondary center of ossification in the distal ephysis Friction between the bones is reduced by a thin layer of articular cartilage covering the surfaces of the bones, and by a lubricating synovial fluid, which is secreted by the synovial membrane. D elastic connective tissue, In the embryo, the bones of the arms and legs are first made of: D) The annular ligament surrounds the head of the radius. The act of increasing the angle between bones is ____________________. Saddle joints have concave and convex surfaces. II. The different types of synovial joints are the ball-and-socket joint (shoulder joint), hinge joint (knee), pivot joint (atlantoaxial joint, between C1 and C2 vertebrae of the neck), condyloid joint (radiocarpal joint of the wrist), saddle joint (first carpometacarpal joint, between the trapezium carpal bone and the first metacarpal bone, at the base of the thumb), and plane joint (facet joints of vertebral column, between superior and inferior articular processes). D growth hormone, The phrase "closure of the epiphyseal discs" means that: Rheumatoid arthritis (RA) is an inflammatory disorder that primarily affects the synovial joints of the hands, feet, and cervical spine. Adduction moves body parts the midine while abduction moves them.

No previous study has investigated the synovial fluid (SF) FA manifestations in these aging-related inflammatory diseases in the shoulder. The tests usually include the following: An exam of physical qualities of the fluid, such as its color and thickness. Joint replacement is a very invasive procedure, so other treatments are always tried before surgery. Suture In some places, an articular disc may act to strongly unite the bones of the joint to each other. a. The articulating surfaces of the bones are covered by articular cartilage, a thin layer of hyaline cartilage. d. Muscle does not attch to muscle; it only attaches to bone. b. d. produce a smooth surface. a. synovial membrane degenrate with age 2 The following is a list of joints' structural classifications.

Proximal radioulnar joint is a type of ellipsoidal joint. True or False: The wrist joint can exhibit adduction and eversion movements. a. articular cartilage at bone ends is replaced with hyaline cartilage d. attach to each other in their midportions, The ligaments that protect the alignment of the femoral and tibial condyles and limit the movement of the femur anteriorly and posteriorly are called ________. D synovial membrane, Which statement is NOT true of the periosteum of a bone? b. a capsule that creates a space in the joint This type of surgery involves replacing the articular surfaces of the bones with prosthesis (artificial components). Which of the following statements is correct? At the shoulder, subacromial bursitis may occur in the bursa that separates the acromion of the scapula from the tendon of a shoulder muscle as it passes deep to the acromion.

Ligaments are classified based on their relationship to the fibrous articular capsule. By the end of this section, you will be able to: Describe the characteristic features for synovial jointsand give examples. D the blood supply to these areas has been closed off, The hormones that increases cell division in growing bones is: b. d. Periosteum. C 8, 2, 2 Synovial foints are and thus allow tor a variety of movemente. The ATP triggers the actin and myosin filaments to shorten, and muscle contraction to occur. Since the rotation is around a single axis, pivot joints are functionally classified as a uniaxial diarthrosis type of joint. How does muscle attach to muscle? The Tissue Level of Organization, Chapter 6. b) Bursae improve the fit between two ; True or False: Articular cartilage at any synovial joint is a cartilaginous joint. d. hinge. c.
