Answer to Question 1

ANS: B
Duchenne muscular dystrophy is an inherited sex-linked disorder caused by a genetic mutation, which results in the absence of a critical protein, dystrophin, which stabilizes the muscle membrane during contraction. When this protein is deficient, muscles degenerate.



Answer to Question 2

ANS: B
In spastic hemiplegia there is involvement of the upper and lower extremities on the same side of the body with the arm more affect than the leg.
