Muscular System  - Individual muscle fibers  - Made of filaments  - Muscle fiber and the motor neuron  - Nerves & muscle fibers that work together to contract  - Membranous network of channels & tubules of a muscle fiber, corresponding to the endoplasmic reticulum  - Neurons communicate with cells that they control by releasing chemicals  - Connective tissue around a muscle  - <span style="font-family: 'Iskoola Pota',serif;">Connective tissue around a bundle of muscle fibers <span style="line-height: normal;
