Muscle movement is controlled by motoneurons. These are nerves which target the muscle, forming junctions called neuromuscular synapses. When the motoneurons fire, they signal to the muscle to instruct it to contract. This image shows two neuromuscular synapses from a mouse muscle. In green are the incoming motoneurons, and in red are the targeted sites in the muscle. The characteristic branched shape of the neuromuscular synapse is often referred to as a 'pretzel'.
