Detailed explanation-1: -Motor neurons of the spinal cord are part of the central nervous system (CNS) and connect to muscles, glands and organs throughout the body. These neurons transmit impulses from the spinal cord to skeletal and smooth muscles (such as those in your stomach), and so directly control all of our muscle movements.
Detailed explanation-2: -Efferent fibers are the axons of motor neurons, and carry data away from the CNS. The two primary efferent systems are the somatic nervous system (SNS) and the autonomic (visceral) nervous system (ANS). The somatic nervous system includes the somatic motor neurons, which innervate skeletal muscles.
Detailed explanation-3: -The somatic nervous system, also called the somatomotor or somatic efferent nervous system, supplies motor impulses to the skeletal muscles. Because these nerves permit conscious control of the skeletal muscles, it is sometimes called the voluntary nervous system.
