Expert Solution

Step 1: Introduction:

Muscle contraction is the activation of tension-generating sites within muscle fibers. In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length, such as when holding a heavy book or a dumbbell at the same position.

Step 2: Options:

Binding of acetylcholine to nicotinic receptors of skeletal muscle directly causes depolarization of skeletal muscle directly. Hence the fifth option is correct.
