What is the consequence of Duchenne muscular dystrophy on skeletal muscle fibers?
A. Complete regeneration of muscle cells.
B. Uncontrolled muscle contractions throughout the body.
C. Damage to the sarcolemma leading to muscle fiber necrosis.
D. Increase in muscle fiber size and strength.
Answer (1)
Duchenne muscular dystrophy primarily causes damage to the sarcolemma of skeletal muscle fibers, leading to muscle fiber necrosis and dysfunction. This condition is characterized by the absence of the dystrophin protein, which results in progressive muscle weakness and the inability to regenerate muscle tissue effectively. The other options provided do not accurately represent the consequences of DMD. ;
