For example, the neuron-neuron contact is called a neuronal synapse. while the neuron-skeletal muscle cell contact is called a neuromuscular or myoneural junction. The contacts made by nerve cells with cardiac muscle, smooth muscle, and gland cells are all neuroeffector junctions.
What happens at the neuromuscular junction? One motor neuron (nerve cell) may stimulate a few muscle cells or hundreds of them, depending on the particular muscle and the work it does. One neuron and all the skeletal muscle cells it stimulates are a motor unit. When a long threadlike extension of the neuron, called the nerve fiber or axon, reaches the muscle, it branches into a number of axon terminals, each of which forms junctions with the sarcolemma of a different muscle cell.
