Nervous System

The nervous system carries messages to and from the brain, spinal cord, and all parts of the body. Learn about the Central Nervous System (CNS) and Peripheral Nervous System (PNS), including the role of the brain, spinal cord, and branching nerves.

Presentation Transcript

  1. Nervous System

  2. Nervous System Carries messages to and from the brain and spinal cord and all other parts of the body.

  3. The Nervous System Consists of the: Brain, Spinal Cord & Branching Nerves

  4. The Nervous System is divided into two systems: Central Nervous System & Peripheral Nervous System

  5. The Central Nervous System

  6. The Central Nervous System consists of the: Brain & Spinal Cord

  7. The Brain is a mass of Nerve Tissue

  8. 3 Parts of the Brain are: 1. Cerebrum 2. Cerebellum 3. Brain Stem

  9. The Cerebrum Controls: Ability to Memorize, Think, & Learn

  10. The Cerebellum Controls: Coordination of muscle activity.

  11. The Brain StemIncludes the Medulla - and controls Involuntary Actions

  12. The Spinal Cord Is a thick band of nerve cells that extends through the backbone. There are 31 pair of spinal nerves branching from it.

  13. The Peripheral Nervous System

  14. The Peripheral Nervous system consists of Cranial Nerves& Spinal Nerves

  15. There are: 12 Pair of CRANIAL NERVESThere are: 31 Pair of SPINAL NERVES

  16. Cranial NervescontrolSenses&Motor Activity

  17. Spinal Nerves TRANSMIT informationTo & From All Parts of the Body

  18. Neurons Are NERVE Cells. There are 2 types of Neurons: Sensory & Motor Neurons

  19. Sensory Neurons: Carry messages FROM sense organs TO the brain.

  20. Motor Neurons: Carries message FROM THE BRAIN TO MUSCLES & GLANDS

  21. Controls ability to memorize, think, learn Controls coordination of Muscle activity Contains the medulla which controls involuntary actions such as heart rate and breathing
