The ability of any motor task depends on more than a muscle simply contracting. Coordinated movement is largely based on the number and type of neural activation to the skeletal muscle. Once a group of fibers are activated, there must also be a constant method of adapting to the changes in the internal and external environments.
Explain what this all means to you in a comment on this post.

Muscle contraction is a lot more complicated then people make it out to be. When a muscle contracts, it is not just a simple movement of an arm but there are amny different components that all have to work to make it possible.
Muscle contracting is more than just a muscle contracting.=] A muscle being able to contract is based on many different things. One thing must happen in order for the next thing to hapeen. A chain reaction must occur in order to contract the muscle.
Muscle contraction is more complicated then people think it is. When a muscle contracts it is not just a simple movement of an arm but there are many different actions and body parts that all have to work to make it happen.
This means that there is more to muscle contraction than people normally think. It takes a lot of little things to make muscles move.
there is more to it than simply moving your arm. when your brain decides to move your arm, it sends a signal down the spine to the arm, and the ability for the arm to move well and strong relies upon how good the nerves are, not just the muscle.
