Definitions:

Motor Units

A single motor neuron and all the muscle fibers it innervates, functioning as the basic functional unit in muscle contraction.

Muscle Twitches

Involuntary, fine movements of a small area of muscle, often caused by stress, fatigue, or mineral imbalances.

All-Or-None Principle

Chemical Process

A process involving chemical reactions in which substances are transformed into different substances, crucial in both biological and industrial contexts.
