Some Random Nervous System Trivia

• Two Parts of the Nervous System• Central Nervous System CNS (blue)

– Brain and spinal cord– Control center

• Peripheral Nervous System PNS (pink)– Made of nerves that transmit

information in the form of electrical impulses from the CNS to the rest of the body

• Brain is protected by skull• Avg. size of adult human brain: 3

pounds

Brain is divided into 3 MAJOR Parts

• Cerebrum– Orange, wrinkly

walnut looking part• Cerebellum– Blue cauliflower

looking thing• Brain Stem– Brown stem looking

thing

Cerebrum

• Largest part of brain• Divided into 2 “cerebral

Hemispheres”• Each hemisphere is divided

into 4 LOBES (FPO-t)– Frontal– Temporal– Parietal– Occipital

Match the picture with the lobe! (might match more than one!)

A. Frontalreasoning, planning, parts of speech, movement, emotions, and problem solving

B. Temporalassociated with perception and recognition of auditory stimuli, memory, and speech

C. Parietalassociated with movement, orientation, recognition, perception of stimuli

D. Occipitalassociated with visual processing

Cerebellum

• Second largest part of brain• “little brain”• JOB: – Coordinate Movements– Posture – Maintain balance– Damage or injury to the part of

this brain will make your movements jerky and uncoordinated

Brain Stem

• Three MAJOR Parts (M-P-M):– Midbrain– Pons– Medulla Oblongata

• Controls MOST important functions that keep us alive

• Automatically controls:– Breathing– Heartbeat– Blood pressure– Circulation

• Imagine if this wasn’t controlled automatically???

• What if you forgot to breathe?? Def NOT good!

• Midbrain– Voluntary motor function– Vision– Hearing– Eye movement– Body movement

• Pons– Motor control– Sensory analysis

• Medulla Oblongata– Maintains VITAL body

functions• Breathing• Heart rate

CerebrumEverything You Need To Know

Know the Different Views

Right Brained vs. left Brained• Right side of the brain is

connected to the left side of the body

• Left side of the brain is connected to the right side of your body

• Reason:– the nerves connecting the brain

and the spinal cord cross to the opposite side.

• Right handed people depend on left side of brain– Good at solving problems,

math, language, analytical• Left handed People depend on

right side of brain– good in music, art, creativity,

story telling
