Somatic motor neurons originate in the central nervous system , project their axons to skeletal muscles ( such as the muscles of the limbs , abdominal , and intercostal muscles ) , which are involved in locomotion . The three types of these neurons are the alpha efferent neurons , beta efferent neurons , and gamma efferent neurons . They are called efferent to indicate the flow of information from the central nervous system ( CNS ) to the periphery .

Question: all the motor neurons that control the skeletal muscles are
Answer: Somatic
