Human Anatomy and Physiology  Coordination of antagonist Skeletal Muscle Movement muscles to perform movement.  The Functional Unit of the Muscle The distribution of the sarcoplasmic reticulum and tubules around myofibrils of skeletal muscle.  Interrelatedness of Neuromuscular System The Mechanism of Contraction of a skeletal muscle requires the coordination of both the muscular and nervous systems. The initiation of a skeletal muscular contraction requires an impulse from a motor Muscle Contraction neuron of the nervous system to trigger a release of the neurotransmitter acetylcholine (ACh), which opens the sodium channels and sets the process of muscle contraction into motion. This all occurs at the neuromuscular junction. Muscular Fuel Thank you
