90) How would blocking the activity of acetylcholinesterase affect skeletal muscle?
A)It would make the muscles less excitable.
B)It would produce muscle weakness.
C)It would cause spastic paralysis (muscles are contracted and unable to relax).
D)It would cause flaccid paralysis (muscles are relaxed and unable to contract).
