How are the effects of denervation and casting similar?

A. Both result in increased moment arms and decreased torque production.
B. Both result in large, sustained decreases in muscle EMG.
C. Both result in increased innervation ratios.
D. Both result in increased connective tissue formation and fibrosis.

Final answer:

Denervation and casting both cause muscle atrophy through decreased use, resulting in decreased torque production and increased connective tissue formation and fibrosis.


Explanation:

Denervation and casting both lead to muscle atrophy due to decreased use, resulting in decreased torque production and increased connective tissue formation and fibrosis. However, they do not result in increased moment arms or increased innervation ratios. Denervation involves the loss of nerve supply to a muscle, while casting restricts movement and leads to muscle disuse.
