A B C D A Answer the following question to test your understanding of the preceding section: \hline They store the calcium ions necessary for muscle contraction Some synovial joints also have an articular disc or a meniscus, both of which can provide padding between the bones, smooth their movements, or strongly join the bones together to strengthen the joint. Joint cavity c. Articular cartilage d. Fibrous articular capsule e. Reinforcing. Correct option is C) Joints are points of contact between bones, or between bones and cartilages. The Tissue Level of Organization, Chapter 6. On the basis of structural classification, which is a fibrous joint?

C yellow bone marrow is mostly adipose tissue These may be located outside of the articular capsule (extrinsic ligaments), incorporated or fused to the wall of the articular capsule (intrinsic ligaments), or found inside of the articular capsule (intracapsular ligaments). If a joint can exhibit flexion, extension, and abduction, then it is triaxial. The calcium binds with troponin on the actin filaments, which permits the myosin heads to latch on and muscle contraction occurs 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. Knee joint (Articulatio genu) The knee joint is a synovial joint that connects three bones; the femur, tibia and patella. B & & & \\ Get started for free!

Gliding movements occur at the intercarpal and intertarsal joints. The present experiment compared the FA alterations between the shoulder and knee joints in patients with end-stage OA or end-stage RA. A) All synovial joints are freely movable. The Cardiovascular System: The Heart, Chapter 20. d. tone, Which of the following is a prime mover in head flexion? a. B the ribs articulate with the thoracic vertebrae It can arise from muscle overuse, trauma, excessive or prolonged pressure on the skin, rheumatoid arthritis, gout, or infection of the joint. Synovial fluid is the clear, viscid, lubricating fluid secreted by synovial membranes. Expert Answers: The scapulothoracic joint is not a true synovial joint.

Which features of synovial joints are credited with providing friction-free movement? ANS: D Feedback A Synovial joints have a cavity. Inflammation occurs in the joint, and the fluid that accumulates causes swelling, stiffness, impairment of joint movement, and extreme pain. The articulating surfaces of the bones are covered by articular cartilage, a thin layer of hyaline cartilage. d. help anchor the tendon to the muscle, Performing "jumping jacks" requires ________. B xiphoid process The intervertebral disc and pubic symphysis are cartilaginous joints, whereas the hip, knee, and shoulder are synovial joints, which are kept together by ligaments. Most joints are synovial joints, such as knees and knuckles. c. the muscle D spare ribs, The manubrium of the _____ articulates with the ______. Examples include the subacromial bursa that protects the tendon of shoulder muscle as it passes under the acromion of the scapula, and the suprapatellar bursa that separates the tendon of the large anterior thigh muscle from the distal femur just above the knee. d. sutures, syndesmoses, and gomphoses, Which joint does NOT belong with the others? In some places, an articular disc may act to strongly unite the bones of the joint to each other. Thus, the thumb can move within the same plane as the palm of the hand, or it can jut out anteriorly, perpendicular to the palm. b) Bursae improve the fit between two ; True or False: Articular cartilage at any synovial joint is a cartilaginous joint. Which of the following is NOT true of synovial joints? At other synovial joints, the disc can provide shock absorption and cushioning between the bones, which is the function of each meniscus within the knee joint. a. suture c. Sutures Tendon sheaths contain a lubricating fluid and surround tendons to allow for smooth movement of the tendon as it crosses a joint. The head of the humerus articulates with the acromion process. The anular ligament surrounds the head of the radius. However, not all of these movements are available to every plane joint due to limitations placed on it by ligaments or neighboring bones. A center of the diaphysis d. intermediate degree of overlap of thick and thin filaments, d. intermediate degree of overlap of thick and thin filaments, Which of the following statements is correct about what happens during flexion? c. masseter d. rotation, Presence of a synovial cavity, articular cartilage, synovial membrane, and ligaments are characteristics of what type of joint? c.

The parts, which are always built in advance of the surgery, are sometimes custom made to produce the best possible fit for a patient. B symphysis/discs of cartilage c. amphiarthrotic joints designed for strength and flexibility d. Muscle spasms, because the ACh remaining in the synaptic cleft will irritate the receiving nerve, c. Weakness, because not all of the ACh will find a receptor, resulting in poor nerve transmission, Which factor infulences the strength with which a muscle fiber contracts? . Note: The thermodynamic cycle involves four piston strokes. Hinge joints, such as at the elbow, knee, ankle, or interphalangeal joints between phalanx bones of the fingers and toes, allow only for bending and straightening of the joint. d. Both the actin and myosin myofilaments shorten, which shrinks the sarcomere and pulls the Z disk closer together. The ability of the bones to move smoothly against each other within the joint cavity, and the freedom of joint movement this provides, means that each synovial joint is functionally classified as a diarthrosis. b. one H zone to the next H zone A synovial joint is characterised by the presence of a fluid-filled joint cavity contained within a fibrous capsule. True or False: Flexion of the ankle so that the superior aspect of the foot approaches the shin is called dorsiflexion. Which of the following are cartilaginous joints? a.

C osteoclasts Describe the characteristic structures found at all synovial joints. Synovial Joints: Synovial joints are joints in the body that are freely movable and classified as diarthrotic. The shallow socket formed by the glenoid cavity allows the shoulder joint an extensive range of motion. For example, in hip arthroplasty, the worn or damaged parts of the hip joint, including the head and neck of the femur and the acetabulum of the pelvis, are removed and replaced with artificial joint components. Planar Joints Planar joints have bones with articulating surfaces that are flat or slightly curved faces. Which of the following joints would allow no movement? a. produce red blood cells. In the classification of joints, which of the following is true? a. fibrous c. incomplete tetanus b. Tetany, because the muscle will fire excessively as the ACh attempts to find a receptor C ethmoid d. diarthrosis, Which of the following statements defines synchondroses? A few synovial joints of the body have a fibrocartilage structure located between the articulating bones. However arthroplasty can provide relief from chronic pain and can enhance mobility within a few months following the surgery. The calcium allows the myosin heads to latch on to the actin filaments and the muscle contraction occurs.
