Motor unit

Clean physiology-style schematic of a single motor unit: one motor neuron with a single axon that branches into multiple fine terminal endings, each contacting a different elongated parallel skeletal muscle fiber. The muscle fibers are shown as a small cluster of striated fibers, with small neuromuscular terminal contacts distributed along them. Stylized colors may depict the motoneuron in yellow and the skeletal muscle fibers in pink-red.
