**[Muscle Cells]** http://www.buzzle.com/images/diagrams/smooth-muscles-cells.jpg The function of muscle cells is to **[cause movement.]** They are arranged in **[bundles]** called **[muscle fibers]**. In order to do this, they have ability to **[contract]** (shorten) so they can pull on things (and cause bones to move). Energy is needed for muscle cells to contract, so they contain **[lots of mitochondria]** to release this energy via respiration.
