- divisions of the nervous system
- Somatic nervous system- Nerves which sends messages from the sense organs to the CNS to the Muscles and glands
- autonomic nervous system- body's involuntary activities such as breathing and digestion
- information conveyed through the NS moves along networks of cells called neurons. These Neurons can only send information one way e.g the sensory neurons and motor neurons
- motor (efferent) neurons
- sensory (afferent)
- peripheral Nervous system- consists of a network of nerves that connects the rest of the body to the central nervous system
- sympathetic Division / Branch- arouses an animal for flight or fight
- parasympathetic divisions/ Branch - returns the body to relaxed stage after the flight or fight response
- brain- responsible for coordinating sensation, intellectual and the nervous system
- Spinal cord- connects all parts of the body with the brain
