What is the difference between the functions of the somatic nervous system from the autonomous?

The somatic nervous system innervates the skin and the musculoskeletal system, establishes relationships with the external environment – perceives its effects (reception), causes skeletal muscle contractions. The autonomous nervous system controls the work of the heart and blood vessels, internal organs and endocrine glands, regulates metabolic processes, growth and reproduction.
The functions of the somatic nervous system: control of human consciousness, perception of the effects of the surrounding world and control of the activity of skeletal muscles. Functions of the autonomic nervous system: regulation of the work of internal organs, glands.
