- The peripheral nervous system is comprised of the somatic nervous system and the autonomic nervous system.
- The somatic sensory nervous system is responsible for afferent nerves transporting information away from the central nervous system.
- The somatic motor nervous system is responsible for efferent nerves sending information away from the brain.
- The autonomic nervous system has two branches: the sympathetic and parasympathetic.
- The sympathetic nervous system directs stress responses, while the parasympathetic system controls reactions occurring when the body is relaxed, such as digestion or defecation.
