1. Warm Up Introduction to the Brain and Nervous System by Jennifer Kenny
Answer both questions on the back in complete sentences

2. Nervous Systems

3. The Nervous System
Function - CARRIES MESSAGES FROM THE BRAIN TO PARTS OF YOUR BODY TELLING THEM WHAT TO DO MOVES INFORMATION THROUGHOUT YOUR BODY

4. The nervous system also allows you to react to a stimulus.
A stimulus is a change in the environment.
Example: A hot stove
Or… tripping over a rock

5. Importance
helps you move, feel, see, hear, taste, smell, learn, form memories and emotion

6. Parts of the Nervous System
Brain
Spinal Cord
Nerves

7. Parts of the Nervous System
Brain = Computer Spinal Cord = Central Cable that carries messages to and from computer Nerves = Keyboard, Mouse connect to spinal cord, carry messages to every part and also back to the brain

8. Stop and Think
Why is the brain like a computer?

9. Kids Health Video

10. Remember AXIAL and APPENDICULAR Skeleton?
Just like the Skeletal System, the Nervous System is divided into 2 parts as well
Central / Autonomic
&
Peripheral

11. Central/Autonomic Nervous System

12. The Central / Autonomic Nervous System
* Controls all of the body’s activities and movement.
* The Central/Autonomic Nervous System is made of two main organs.
1. The brain
2. The spinal cord

13. The Spinal Cord
* Function: carries messages between brain and nerves around body

14. The Spinal Cord
Importance:
connects the brain to the rest of the nervous system, without it brain couldn’t get messages to body

15. The Vertebrae
* The vertebrae are the many bones that protect the nerves in the spinal cord.

16. Stop and Think
Why is our spinal cord inside our vertebrae?

17. The Brain
* The brain controls/manages everything in the body.
The brain is made of more than 10 billion nerves and weighs about 3 pounds
* The brain is divided into three parts and is protected by the skull.

18. The Three Main Parts of the Brain
* The Brain has three main parts…
1. The Cerebrum
2. The Cerebellum
3. The Brain Stem

19. * Largest part of the brain. The top half
The Cerebrum
* Largest part of the brain. The top half
The cerebrum controls 1.thinking & emotions
2. memory
3. speaking.
4. movement

21. * Below and to the back of the cerebrum.
The Cerebellum
* Below and to the back of the cerebrum.
controls 1. balance.
2. posture.

24. The Brain Stem
* The Brain Stem connects the brain to the spinal cord.
* The nerves in the brain stem control all involuntary movements like your heartbeat, breathing, and blood pressure.

27. The Brain Diagram

The Nervous System
The Brain

29. Exit What role does the brain play in the nervous system?
What do you think life would be like if your spinal cord did not connect to the rest of your body?

30. Quiz Return
19 – 18 = A
17 – 16 = B

31. Warm Up – put hw on desk to be checked
Answer the questions below. 2 and 3 must be answered in complete sentences
The cerebrum controls
Thinking
Speaking
Movement
All of the above
2. What 2 organs make up the central nervous system?
3. Why is the vertebrae important?

32. 2. What 2 organs make up the central nervous system?
Brain
Spinal Cord
3. Why is the vertebrae important?
The vertebrae protects the spinal cord.

33. Goals Central Nervous System - what does that mean? - What does it do?
What parts are in it?
Brain > function and location of each part

34. Parts of Brain & Functions
Cerebrum > thinking, emotion, memory, speaking, movement *SENSES
sight, taste, touch, hear, smell
Cerebellum > balance and posture
Brain Stem > all involuntary movements
- Heart beat, heart rate, breathing, blood pressure

35. Video Brain = http://www.brainpop.com/health/bodysystems /brain/
Spinal Cord =
pinalcord/

36. 2 “parts” of the nervous system
Central / Autonomic = Brain & Spinal Cord Function = controls all of the voluntary and involuntary movement in your body

37. Brain & Spinal Cord Activities
The Nervous System – Brain handout (cross out #7)
What are the Parts of the Brain? handout
The Brain Poster
Your Nervous System – Ready for Action Article and Questions
Brain Origami
* After finishing an activity you must check for correctness before moving on
If answer are wrong, try again
If correct move on to next assignment

38. Exit Ticket
You are memorizing vocab words for a quiz, which part of the brain is working for you to memorize?
Your heart is beating, which part of the brain controls that?

39. Warm Up Put yesterday’s HW on desk
Copy the sentences and fill in the blanks.
The 3 parts of the brain are the ___________, __________ and _________.
Balance and posture are controlled by the _____
The Central Nervous system is made up of the ____________ and _________

40. The Peripheral Nervous System

41. Peripheral Nervous System
Made up of the nerves/neurons that come from the brain and spinal cord

42. Peripheral Nervous System
* and the sense organs.
Eye
Tongue
Ear
Nerves
Skin

43. Function
To connect the central nervous system to the limbs (arms & legs) and organs all around the body

45. Neuron
What is it?
A nerve cell, it is one of 2 main types of cells found in the nervous system.
Function
Carry messages to and from the brain through the spinal cord to every part of the body

46. Types of Neurons
Motor neurons – work with muscles to make movement possible Sensory Neurons – bring messages from senses to our brain

47. Other info
- human body is made of billions of neurons - Neurons connect to other neurons to make pathways or tracts for messages to travel down

49. What does a neuron look like?

50. Myelin
Dendrites
Cell Body
Axon

51. Functions of Neuron Parts
Dendrite = part of the neuron that receives messages from other neurons Axon = receives messages from the cell body and send the messages to dendrites of other neurons Cell Body = Controls whether a message is sent to the axon Myelin = fatty substance that covers/protects the axon

52. Messages are sent through Neuron chains
Synapse = gap between the axon of one cell and the dendrite of another

53. Dendrite Cell Body Axon

55. Sense Organs
Sense organs carry messages about the environment to the central nervous system.

56. What are sense organs? The organs in your body that allow you to sense
Eyes
Ears
Nose
Tongue
Skin

57. Vision is your ability to see.
*Optic nerves in the eye carry the image from the back of the eye to the brain

59. When a sound is made, the air around the sound vibrates.
Hearing
vibrations travel inside head and turn into signals.
*Vestibular nerves in ear send signals to the brain and a message telling us what the sound means is made

60. All of your movements are controlled by balance and muscles.
The Ear and Balance
*The liquid in your inner ear works with the brain to control your balance.
All of your movements are controlled by balance and muscles.

62. The sense of touch is located in the skin.
The sensory receptor nerves in the skin allow us to feel texture, pressure, heat, cold, and pain.

63. The nose is able to smell 80 different kinds of smells.
*Sense Receptors in the nose control your sense of smell.
Smell
The nose is able to smell 80 different kinds of smells.
Scientists don’t understand anything about how our sense of smell works !!

64. Your sense of taste comes from the taste buds in the tongue.
*Taste buds (small lumps of sensing tissue) are the parts on the tongue that allow us to taste.
The four kinds of taste buds are sweet, sour, bitter, and salty.

66. What type of neuron deals with the senses?
Sensory Neurons

67. Exit.
