Organs of the Nervous System Brain= uses information it receives from nerve impulses to coordinate actions http://commons.wikimedia.org/wiki/File:Brain_headBorder.jpg
Organs of the Nervous System Nerves= carry messages throughout the body http://commons.wikimedia.org/wiki/File:TE-Nervous_system_diagram-la.svg
Organs of the Nervous System Spinal Cord= Central communication system. Nerve center Messages are sent to the brain through the spinal cord. Exception: Reflexes skip the spinal cord and go straight to the brain. http://commons.wikimedia.org/wiki/File:Spinal_cord.gif
Functions of the Nervous System Functions include: Control center Communication network Coordinates all actions and reactions Send messages as electrical impulses http://commons.wikimedia.org/wiki/File:TE-Nervous_system_diagram-la.svg
Functions of the Nervous System Functions include: Allows us to Think Evaluate Remember http://commons.wikimedia.org/wiki/File:TE-Nervous_system_diagram-la.svg
Functions of the Nervous System Functions include: Sensory Input- Senses send messages to the brain. Integration- The brain interprets and translates. Motor Output- The brain sends messages to body. http://commons.wikimedia.org/wiki/File:TE-Nervous_system_diagram-la.svg
Functions of the Nervous System Functions include: – Central Nervous System- Maintains homeostasis by regulating vital body functions such as breathing, heart rate, hormones, etc. http://commons.wikimedia.org/wiki/File:TE-Nervous_system_diagram-la.svg
Functions of the Nervous System Functions include: – Peripheral Nervous System- Sensory Neurons- Carry information toward the central nervous system Motor Neurons- Send impulses away from the central nervous system http://commons.wikimedia.org/wiki/File:TE-Nervous_system_diagram-la.svg
