Central NervousSystem • Itconsists of thebrain and spinalcord. • Itsendsout impulses and tellsthebrainthesensesyouperceive.
PeripheralNervousSystem Itisdividedinto: • TheAutonomicNervousSystem • SensoryReceptors • 5 senses
AutonomicNervousSystem Itregulatesourinvoluntaryactionslike: • Digestingfood • Keepingheartbeating
Brain Itisdividedinto 5 parts. • Thecerebrum • Thecerebellum • Thebrainstem • Thethalamus • Thehypothalamus
TheCerebrum • Responsable forvoluntaryacts. • Contains: intelligence, learning, judgment. • Dividedinto: Left and Righthemispheres. • Oneanalytic and theotherartistic.
TheCerebellum • Located at the back of theskull. • It balances actions in themuscles.
TheBrainStem • Itregulatestheflow of informationbetweenbrain and body. • Dividedintothepons and themedullaablangata.
TheThalamus • Receivesmessagesfromthesenseorgans. • Ittransportsthemto a certainpart of thecerebrum.
TheHypothalamus Locatedunderthalamus. Recognizes+ Analyzes: • Hunger • Thirst • Fatigue • Anger • BodyTemperature
SensoryReceptors • PainReceptors • Thermoreceptors • Mechanoreceptors • Chemoreceptors • Photoreceptors
Neuron • Cellsthattransmitelectricalsignalscalled impulses.
Depressants • Slowdownheartrate. • Slowdownbreathingrate. • Lowerbloodpressure. • Relax muscles. • Relieftension.
Stimulants Increase: • Bloodrate • Heartrate • Breathingrate
Vision • Eye: senseorganthatwe use tosense light.
Hearing • Ears: we can distinguishthe pitch of thevibrations in the air.
