The Peripheral Nervous System includes both [[#Innervation - cranial nerves| cranial nerves]] and [[#Innervation - spinal nerves| spinal nerves]], and is commonly divided into the somatic nervous system and the autonomic nervous system. The [[Somatic Nervous System - Anatomy & Physiology|somatic nervous system]] co-ordinates body movements and also receives external stimuli. It basically regulates activities that are under conscious control.

The [[Autonomic Nervous System - Anatomy & Physiology|autonomic nervous system]] contains the [[Sympathetic Nervous System - Anatomy & Physiology|sympathetic nervous system]] and the [[Parasympathetic Nervous System - Anatomy & Physiology|parasympathetic nervous system]] as well as an enteric division. The sympathetic nervous system is the ‘fight or flight’ system which comes into role when an animal is under threat, it's main neurotransmitter is adrenaline. The parasympathetic nervous system is the ‘rest and digest’ system which is responsible for digestion; the primary neurotransmitter is acetylcholine.
