How do muscles work?

Answer 1

My second reference requires that you accept a download onto your hard drive - but it is worth it.

There are three types of muscle; involuntary (e.g. gut muscles), cardiac (heart) and voluntary (skeletal). I suspect you are mostly interested in the muscles attached to your skeleton.
Nerve impulses arrive at various places in a muscle, onto individual muscle fibres (there are hundreds within one muscle) at locations called neuro-muscular junctions. The electrical nerve impulse is converted into into a chemical messenger (acetylcholine) which crosses the neuromuscular junction and initiates a series of chemical changes within muscle fibres that result in the contraction of the muscle fibre.
