Becker's muscular dystrophy in the arms, neck, and other areas, but not as noticeably severe as in the lower half of the body. Calf muscles initially enlarge during the ages of 5-15 (an attempt by the body to compensate for loss of muscle strength), but the enlarged muscle tissue is eventually replaced by fat and connective tissue (pseudohypertrophy) as the legs become less used (with use of wheelchair). Possible complications associated with muscular dystrophies (MD) are cardiac arrhythmias. Becker muscular dystrophy (BMD) also demonstrates the following: The disorder is inherited with an X-linked recessive inheritance pattern. The gene is located on the X
Muscular hydrostat a constant diameter. Bending of a muscular hydrostat can also occur by the contraction of transverse, radial, or circular muscles which decreases the diameter. Bending is produced by longitudinal muscle activity which maintains a constant length on one side of the structure. The bending of a muscular hydrostat is particularly important in animal tongues. This motion provides the mechanism by which a snake flicks the air with its tongue to sense its surroundings, and it is also responsible for the complexities of human speech. The stiffening of a muscular hydrostat is accomplished by the muscle or connective tissue of the
