nerve cells that carry response information to muscles and other organs

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: -Motor neurons carry instructions from the brain along axons that stretch from the spinal cord to the muscles in the hands and feet.
Detailed explanation-3: -The dendrites of neurons receive information from sensory receptors or other neurons. This information is then passed down to the cell body and on to the axon.
Detailed explanation-4: -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.
