There are three types of muscles.

There are ones that you have to think about before they will move. These are called voluntary muscles. Some names for these are the biceps (upper arm), masseter (jaw) and quadriceps (upper leg).

There are ones you don't have to think about and these are called involuntary muscles. These are found in all hollow organs.

And lastly, there are ones only found in the heart and these are called cardiac muscles.

All of these muscles use the sliding filament model of contraction. The only difference is in the way that the brain and nervous system interact.
