Neuromuscular Junction Skeletal muscle cells contract as a result of impulses from motor neurons. The place where a motor neuron stimulates a muscle cell is called a neuromuscular junction. In order for skeletal muscle cells to contract each cell must be stimulated by a process of a motor neuron.Sliding Filament Theory The theory of how muscle contracts is the sliding filament theory.The contraction of a muscle occurs as the thin filament slide past the thick filaments.n skeletal muscle, the cells never contract individually. Rather they contract as groups of muscle cells that are collectively connected to a motor nerve originating in the spinal cord. The combination of the motor nerve cell (neuron) and the muscle cells it innervates is known as the motor unit.
FIGURE 5.35 Label: muscle fibers, endomysium, perimysium, epimysium, fascicle 11) The Neuromuscular Junction Voluntary muscle cells are always stimulated by motor neurons via nerve impulses. The junction between a nerve fiber (axon) and a muscle cell is called a neuromuscular, junction.
