Specifically, the somatic nervous system is responsible for the movement of voluntary muscles and the process known as a reflex arc. This system carries nerve impulses back and forth between the central nervous system, which is the brain and the spinal cord and the skeletal muscles, skin, and sensory organs.
Smooth muscle cells are found in the walls of hollow organs like stomach, intestines, urinary bladder etc. Cardiac muscles are involuntary muscles.
