Presentation Transcript

  1. Nervous System

  2. Nervous System • How did our nervous system work in the Impulse Activity we just completed? • We sensed the touch. • A message was sent to our brain. • Our brain sent a message to our muscles. • Our muscles squeezed the hand.

  3. Organs of the Nervous System Brain= uses information it receives from nerve impulses to coordinate actions

  4. Organs of the Nervous System Nerves= carry messages throughout the body

  5. 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.

  6. Functions of the Nervous System Functions include: • Control center • Communication network • Coordinates all actions and reactions • Send messages as electrical impulses

  7. Functions of the Nervous System Functions include: • Allows us to • Think • Evaluate • Remember

  8. 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.

  9. Functions of the Nervous System Functions include: – Central Nervous System- Maintains homeostasis by regulating vital body functions such as breathing, heart rate, hormones, etc.

  10. 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
