Nervous System Review

Front 1

What is the function of the Cerebrum?

Back 1

Where thinking and problem solving occurs, voluntary movements, and most memories are stored.

Front 2

What is the function of the brainstem?

Back 2

Connects your brain to your spinal cord, controls involuntary processes such as heart rate, blood pressure and body temperature

Front 3

What is the function of the cerebellum?

Back 3

Coordinates movements, keeps track of the body’s position

Front 4

What is the structure of the Dendrites?

Back 4

Short branches of the cell body of a neuron

Front 5

What is the function of the Dendrites?

Back 5

Collect messages from surrounding cells (move messages towards the cell body)

Front 6

What is the structure of the axons?

Back 6

Long extensions of the cell body of a neuron

Front 7

What is the function of the axons?

Back 7

Sends messages away from the cell body towards the axon terminals

Front 8

A cat scrathces your hand. What information is being sent by your sensory neurons to your hand?

Back 8

OUCH!! Your sensory neurons feel pain from the scratch.

Front 9

A cat scratches your hand. What information is being sent by your motor neurons to your hand?

Back 9

Your motor neurons tell you to move your hand away from the evil cat.

Front 10

You are at the pool and someone dives into the shallow area head first, even though it says No Diving! Explain what might happen to this person if their spinal cord is damaged at their neck.

Back 10

If the person’s spinal cord is damaged at their neck, they may lose part or all of the functions of their body parts below the damaged area. They could become permanently paralyzed and in a worst case scenario, they could die.

Front 11

MS, or Multiple Sclerosis is a disease of the Nervous System that affects the myelin sheath of neurons, which causes many problems for people who have the disease. Explain why this disease causes problems for people, be sure to describe both the STRUCTURE and the FUNCTION of the myelin sheath.

Back 11

Multiple Sclerosis affects the myelin sheath which is the protective covering around the axon of a neuron made of proteins and fats that insulates the electrical impulses inside of the axon. It keeps the impulses from exiting the axon and allows the impulses to travel to their destination quickly. If the myelin sheath gets damaged, the impulse or “message” could get lost on the way to a body part or could move very slowly, making the function of the body part ineffective.

Front 12

Label the following options with the appropriate part of the nervous system that it is describing: Includes the brain and the spinal cord

Back 12

Central Nervous System

Front 13

Label the following options with the appropriate part of the nervous system that it is describing: Carries messages to your toes

Back 13

Peripheral Nervous System

Front 14

Label the following options with the appropriate part of the nervous system that it is describing: Has two main parts- the sensory part and the motor part

Back 14

Peripheral Nervous System

Front 15

Label the following options with the appropriate part of the nervous system that it is describing: Part of this is protected by the vertebrae

Back 15

Central Nervous System

Front 16

Label the following options with the appropriate part of the nervous system that it is describing: Carries messages to your lungs

Back 16

Peripheral Nervous System

Front 17

Label the following options with the appropriate part of the nervous system that it is describing: Part of this is made up of the body’s central command organ

Back 17

Central Nervous System

Front 18

You are sitting outside when you feel a raindrop land on your face. Show how the message moves through your body.

Back 18

You feel the rain drop (stimulus), Sensory Neurons send the message, Your brain receives the message, Your brain processes the message, Your brain sends the message, Motor Neurons send the message, Your muscles receive the message and you run inside.

Front 19

State what type of cell is being used, and how its helps us : Sight

Back 19

Photoreceptors- Rods and Cones. Turns light into electrical impulses

Front 20

State what type of cell is being used, and how its helps us : Touch

Back 20

Touch Receptors. Allows us to feel things in our environment and protects us from things that could cause pain, such as fire or sharp objects.

Front 21

State what type of cell is being used, and how its helps us : Hearing

Back 21

Hair cells. Maintain balance and interpret sound

Front 22

State what type of cell is being used, and how its helps us : Taste

Back 22

Taste cells clump together to form taste buds. Allows us to detect the chemicals and molecules in food and to determine if something is safe to eat or not.

Front 23

State what type of cell is being used, and how its helps us : Smell

Back 23

Olfactory cells. Allows us to detect dissolved particles in the air and to smell if something is dangerous, like poisonous gases.
