3 Parts of the Brain
The functions of each part—their job
WS due February 19th
Brain

Brain- controls thinking, reasoning,
remembering, controls movement…..It is
the ‘Master Control’

It is the ‘computer’ of the body
3 Parts of the Brain
Cerebrum- This part is in charge of thinking,
learning, talking, memory, and the five senses
 Cerebellum- This part controls all voluntary
muscles, so it controls the skeletal muscles
 Medulla- This part controls breathing. It controls
all involuntary muscle movements. Heartbeat &
digestion
*** If the medulla is damaged, you will die

Diagram of the Brain
7. Cerebrum 85%-Green
8. Cerebellum 5%-Blue
9. Medulla 10%-Red
The brain is divided
into two hemispheres
DID YOU KNOW
Grinder-teeth, stomach, intestine
Motor-heart
Computer-brain
Camera-eyes
Medulla is also
called the ‘brain stem’

 What the spinal cord does
 What nerves do
 Draw a nerve impulse

Spinal Cord


Spinal Cord- bundle of nerve cells. Spinal
cord carries messages to and from the
brain.
If the spinal cord is damaged a person is
paralyzed
Nerves

Nerves- are threadlike cells throughout the
body that carry messages to and from the
brain.
Nerve Impulse
Dendrites, Cell body, Axon, End brush

 To Understand Sensory & Motor Nervous
 To understand how drugs effect the Nervous System
2 Types of Nerves in the Body
Sensory Nerve- Nerves that carry messages
to the brain
 Motor Nerve- Nerves that carry messages
from the brain to the muscles
 Reflex- is a special action which involves
only the nerves and spinal cord…keep you
out of danger.
***Example touching a hot stove

Drugs that Effect the Nervous
System




Drugs- are chemicals that cause change in
the body
Caffeine- a drug that will speed up the
nervous system- Example- pop & coffee
Nicotine- a drug found in tobacco. It speeds
up the nervous system
Alcohol- A drug which slows down the
nervous system. Example- beer & wine
