3 The Nervous SystemFunction - 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 stoveOr… tripping over a rock
5 Importancehelps you move, feel, see, hear, taste, smell, learn, form memories and emotion
6 Parts of the Nervous System BrainSpinal CordNerves
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
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 brain2. The spinal cord
13 The Spinal Cord* Function: carries messages between brain and nerves around body
14 The Spinal CordImportance: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 ThinkWhy 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 Cerebrum2. The Cerebellum3. The Brain Stem
19 * Largest part of the brain. The top half The Cerebrum* Largest part of the brain. The top halfThe cerebrum controls 1.thinking & emotions2. memory3. speaking.4. movement
31 Warm Up – put hw on desk to be checked Answer the questions below. 2 and 3 must be answered in complete sentencesThe cerebrum controlsThinkingSpeakingMovementAll of the above2. 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? BrainSpinal Cord3. 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 *SENSESsight, taste, touch, hear, smellCerebellum > balance and postureBrain Stem > all involuntary movements- Heart beat, heart rate, breathing, blood pressure

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? handoutThe Brain PosterYour Nervous System – Ready for Action Article and QuestionsBrain Origami* After finishing an activity you must check for correctness before moving onIf answer are wrong, try againIf correct move on to next assignment
38 Exit TicketYou 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 _________
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
59 When a sound is made, the air around the sound vibrates. Hearingvibrations 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.SmellThe 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.How many parts does a neuron have?What is the job of a neuron?If the brain wants your big toe to move, how does that message get to your toe?
68 Warm Up – put HW on desk Copy the sentence and fill in the blank The peripheral nervous system is made up of _____________ and _____________.The 4 parts of a neuron are the _________,__________, _________ and _________.3. The 2 types of neurons are ______ and _____.
69 The peripheral nervous system is made up of Nerves/Neurons and sense organs. The 4 parts of a neuron are the DENDRITE,AXON, CELL BODY and MYELIN.3. The 2 types of neurons are SENSORY and MOTOR
70 Warm UpTake out both nervous system packets, copy and answer the following questions. No talking!!!!!!!The parts of the body that make up the Peripheral Nervous System are the _______ and __________.A _____________ has 4 parts and carries message sent from the brain all over the body.A __________ is the part of a neuron that sends the messages to the next neuron.
71 The parts of the body that make up the Peripheral Nervous System are the NERVES/NEURONS and SENSE ORGANS.A NEURON has 4 parts and carries message sent from the brain all over the body.A AXON is the part of a neuron that sends the messages to the next neuron.
