    • 1. NERVOUS SYSTEMPREPARED BY: FRANCIA G. BAJARO 1
    • 2. I. OBJECTIVES•The learners must be able to explain how the nervous system works.•The pupils are expected to identify and describe the main parts of the nervoussystem•Students will learn the locations and functions of the Central Nervous System (brain and spinal cord) and the Peripheral Nervous System 2
    • 3. II.INTRODUCTIONThe human nervous system is a system of nerves thatbegins in the brain and is part of every area of yourbody – from your fingertips to your eyes, from the skinon your toes to your bones, tendons and ligaments.The nervous system is designed to help humansperceive the world around them and to keep them safe.A simple example of the human nervous system iswhen your finger or hand gets too close to a heatsource and you instinctively pull back. Your brain andnerve endings feel the heat and signal your muscles toretract your hand. 3

    • 7. THE NERVOUS SYSTEM ∞ The nervous system is a very complex system in the body. ∞ It is divided into two main systems. ∞ The central nervous system (CNS) ∞ Consists of spinal cord and the brain. ∞ The peripheral nervous system is made up of all of the nerves and the wiring. 7 Copyright©2010 Companynamehttp://www.3dscience.com/3D_Models/Human_Anatomy/Male_Systems/Male_Nervous_3.php Free template by Investintech PDF Solutions
    • 8. The two main parts of the nervous systemhttp://morphonix.com/software/education/science/brain/game/specimens/images/nervous_system.gif 8
    • 9. Central Nervous System "Brain & Spinal Cord"The BRAIN keeps the body in order. It helps to controlall of the body systems and organs, keeping themworking like they should. The brain. also allows us tothink, feel, remember and imagineIn general, the brain iswhat makes us behave as human beings.The brain communicates with the rest of thebody through the spinal cord and the nerves.They tell the brain what is going on in thebody at all times. This system also givesinstructions to all parts o the body what to do and when to do it.http://library.thinkquest.org/5777/ner1.htm 9
    • 10. Parts of the Brain 1=olfactory lobe of • cerebrum, 2=thalamus, 3=pineal gland, 4=hypothalamus, 5=anterior pituitary, 6=posterior pituitary, 7=cerebellum, 8=brain stem 10Copyright©2010 Companyname http://loudoun.nvcc.edu/vetonline/vet111/nervous%20sys/nervoussysless.htmFree template by Investintech PDF Solutions
    • 11. Cerebrum (cerebral hemispheres): •This is the largest portion of the brain in higher animals, The cerebral surface appears gray and "furrowed" by the sulci (valleys) and gyri (hills ). •The cerebrum is the seat of the highest mental activity including: memory, language, reason, emotion (along with the limbic system), voluntary body control and interpretation of sensations. •It is divided into two halves by a deep mid line fissure. 11
    • 12. •Cerebellum: •The "little brain" located at the back of cerebrum and appears similar to the cerebrum but smaller. •It coordinates the execution of movement and is involved in the unconscious control of balance. (receives information from receptors in joints and muscles) 12
    • 13. •Pineal body: • It is located above the pituitary gland, deep in the brain. (It is actually an endocrine gland and secretes releasing factors to the pituitary gland and the hormone melatonin.)•Thalamus: • The thalamus is the "switchboard" to the cerebrum, it controls and integrates the millions of messages sent to the brain. 13
    • 14. •Hypothalamus: It acts in the regulation ofsome autonomic functions including hunger,thirst and body temperature. It is veryimportant in regulation of the pituitary gland. 14
    • 15. •Medulla Oblongata: The medulla or brainstem is a primary regulator of autonomicfunctions including respiration, bloodpressure, heart rate, coughing and vomiting 15
    • 16. Did you know…. The most brainless animal may have been the dinosaur, Stegosaurus. It weighed 1 1/2 tons, but its brain was only the size of a walnut. 16
    • 17. Central Nervous "Senses" There are five main senses touch, smell, taste, hearing and sight. These are the external sensory system, because they tell you about the world outside your body. Your senses tell you what is happening in the outside world. Your bodys sense organs constantly send signals about what is happening outside and inside it to your control center - the brain Sensory areas such as touch, smell, taste, hearing and sight receive messages from the skin, nose, mouth, ears and eyes. We feel, t aste, hear and see when these messages are received by the sensory parts of the brain . 17
    • 18. "Senses" 18Copyright©2010 CompanynameFree template by Investintech PDF Solutions
    • 19. Did you know…. Lizards are always flicking their tongues in and out. They "taste" the air and pass all the flavors back to a sense organ in the mouth. 19
    • 20. Spinal Cord Specialized nerves divide many times as they leave the spinal cord so that they may reach all parts of the body. The thickest nerve is 1 inch thick and the thinnest is thinner than a human hair. Each nerve is a bundle of hundreds or thousands of cells. The spinal cord runs down a tunnel of holes in your backbone or spine. The bones protect it from damage. The cord is a thick bundle of nerves, connecting your brain to the rest of your body http://library.thinkquest.org/5777/ner1.htm 20Copyright©2010 CompanynameFree template by Investintech PDF Solutions
    • 21. The peripheral nervous system•The peripheral nervous system carriesmessages to and from the central nervoussystem. It sends information to the brain andcarries out orders from the brain.•Messages travel through the cranial nerves,those which branch out from the brain andgo to many places in the head such as theears, eyes and face. Messages can alsotravel through the spinal nerves whichbranch out from the spinal cord.http://www.cyh.com/HealthTopics/HealthTopicDetailsKids.aspx?p=335&np=152&id=2612 21
    • 22. The Peripheral Nervous SystemThe nervous system is made up of nerve cellsor neurons that are "wired" together throughoutthe body, somewhat like communicationsystem. Neurons carry messages in the formof an electrical impulses. The messages movefrom one neuron to another to keep the bodyfunctioning.Neurons have a limited ability to repairthemselves. Unlike other body tissues, nervecells cannot also be repaired if damaged dueto injury or disease. 22 http://library.thinkquest.org/5777/ner1.htm
    • 23. Did you know…. The axon of one neuron doesnt touch the dendrites of the next. Nerve signals have to jump across a tiny gap. To get across the gap they have to change from electrical signals into chemical signals then back into electrical signals. http://library.thinkquest.org/5777/ner1.htm 23
    • 24. Dr. Amriel says… You can help your nervous system work well and be healthy by being active, having a healthy diet and keeping yourself busy and happy.What are the health habits that can make thenervous system healthy?http://www.cyh.com/HealthTopics/HealthTopicDetailsKids.aspx?p=335&np=152&id=2612 24
    • 25. Dr. Amriel says•Exercise releases a chemical, calledserotonin, in the brain which makesyou feel good, relaxes muscles andgets rid of stress.•Good food gives your body thevitamins and minerals needed to buildhealthy nerves and tissue.•Keeping busy and happy helps you todeal with life when things go wrong.http://www.cyh.com/HealthTopics/HealthTopicDetailsKids.aspx?p=335&np=152&id=2612 25
    • 26. What makes up the brain, the spinal cord oryour peripheral nerves? •Neurons are “the cell” •Cell body •Nucleus •Axon •Dendrite •What do you think surrounds the cell? • What other organelles would be needed? http://loudoun.nvcc.edu/vetonline/vet111/nervous%20sys/nervoussysl ess.htm 26
    • 27. ACTIVITIES Simple Neuron Model Picture description text Heres the most simple model of a neuron I can think of...and you dont need any supplies. Its your hand! Procedure : 1. Hold out your arm and spread your fingers. 2. Your hand represents the "cell body" (also called the "soma"); your fingers represent "dendrites" bringing information to the cell body; your arm represents the "axon" taking information away from the cell body. 27Copyright©2010 CompanynameFree template by Investintech PDF Solutions ALRIGHT!
