  2. Central NervousSystem • Itconsists of thebrain and spinalcord. • Itsendsout impulses and tellsthebrainthesensesyouperceive.

  3. PeripheralNervousSystem Itisdividedinto: • TheAutonomicNervousSystem • SensoryReceptors • 5 senses

  4. AutonomicNervousSystem Itregulatesourinvoluntaryactionslike: • Digestingfood • Keepingheartbeating

  5. Brain Itisdividedinto 5 parts. • Thecerebrum • Thecerebellum • Thebrainstem • Thethalamus • Thehypothalamus

  6. TheCerebrum • Responsable forvoluntaryacts. • Contains: intelligence, learning, judgment. • Dividedinto: Left and Righthemispheres. • Oneanalytic and theotherartistic.

  7. TheCerebellum • Located at the back of theskull. • It balances actions in themuscles.

  8. TheBrainStem • Itregulatestheflow of informationbetweenbrain and body. • Dividedintothepons and themedullaablangata.

  9. TheThalamus • Receivesmessagesfromthesenseorgans. • Ittransportsthemto a certainpart of thecerebrum.

  10. TheHypothalamus Locatedunderthalamus. Recognizes+ Analyzes: • Hunger • Thirst • Fatigue • Anger • BodyTemperature

  11. SensoryReceptors • PainReceptors • Thermoreceptors • Mechanoreceptors • Chemoreceptors • Photoreceptors

  12. Neuron • Cellsthattransmitelectricalsignalscalled impulses.

  13. Depressants • Slowdownheartrate. • Slowdownbreathingrate. • Lowerbloodpressure. • Relax muscles. • Relieftension.

  14. Stimulants Increase: • Bloodrate • Heartrate • Breathingrate

  15. Vision • Eye: senseorganthatwe use tosense light.

  16. Hearing • Ears: we can distinguishthe pitch of thevibrations in the air.
