Motor unit

- consists of a single motoneuron and the muscle fibers that it innervates. For fine control (e.g., muscles of the eye), a single motoneuron innervates only a few muscle fibers. For larger movements (e.g., postural muscles), a single motoneuron may innervate thousands of muscle fibers.

- The motoneuron pool is the group of motoneurons that innervates fibers within the same muscle.

-The force of muscle contraction is graded by recruitment of additional motor units (size principle). The size principle states that as additional motor units are recruited, more motoneurons are involved and more tension is generated.
