The compression ratio of an Otto cycle is VA/VB=8.00V_{A} / V_{B}=8.00VA/VB=8.00. What caused this patients weakness? An example is the first carpometacarpal joint located at the base of the thumb. Adduction moves body parts the midine while abduction moves them. This type of joint is found between the articular processes of adjacent vertebrae, at the acromioclavicular joint, or at the intercarpal joints of the hand and intertarsal joints of the foot. Also classified as a synchondrosis are places where bone is united to a cartilage structure, such as between the anterior end of a rib and the costal cartilage of the thoracic cage. Freely movable (synovial) joints are most abundant and include six types: pivot, hinge, condyloid, saddle, plane, and ball-and-socket joints. This membrane produces a special fluid to lubricate the joint and prevent wear on cartilage while the joint is in motion.

The most common type of arthritis is osteoarthritis, which is associated with aging and wear and tear of the articular cartilage (Figure 9.4.4). 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.

Sarcomeres This type of surgery involves replacing the articular surfaces of the bones with prosthesis (artificial components). They are enclosed by a capsule. This type of joint allows only for bending and straightening motions along a single axis, and thus hinge joints are functionally classified as uniaxial joints. A ball-and-socket joint is a multiaxial joint. b. Bursae serve as cushioning fat pads between adjacent structures, while tendon sheaths reduce friction between adjacent structures.

B oseoblasts c. tibial collateral ligaments The mysosin heads propel the actin myofilaments toward the center of the sarcomere; this pulls the Z disks closer together, which shortens the sarcomere and the entire muscle, Which statement correctly describes the sequence of events in the muscle contraction? An extrinsic ligament is located outside of the articular capsule, an intrinsic ligament is fused to or incorporated into the wall of the articular capsule, and an intracapsular ligament is located inside of the articular capsule. The six types of synovial joints are pivot, hinge, condyloid, saddle, plane, and ball-and socket-joints (Figure 9.4.3). Pivot joints only allow for rotation around a single axis. A subtendinous bursa is found between a tendon and a bone. A tendon is the dense connective tissue structure that attaches a muscle to bone. An Introduction to the Human Body, Chapter 2.
