Peripheral Nervous System (PNS) The sensory and motor nerves that connect the central nervous system to the rest of the body Peripheral means “outer region” The system is subdivided into the somatic and autonomic nervous systems.
Somatic Nervous System The division of the peripheral nervous system that controls the body’s skeletal muscles Contains the motor nerves needed for the voluntary muscles Ex. – your CNS develops idea to walk – your motor and sensory nerves in SOMATIC NS carry out the command
Autonomic Nervous System (think autopilot) The division of the peripheral nervous system that controls the glands and muscles of the internal organs Monitors the autonomic functions Controls breathing, blood pressure, and digestive processes (you don’t control these – they happen on their own) Divided into the sympathetic and parasympathetic nervous systems
