Presentation Transcript

  1. Aim: What are the major parts to the Nervous System? • Do Now: What is a neuron? • Vocabulary: Neurons, impulses, synapse, neurotransmitters, sensory neurons, inter neurons, motor neurons, Peripheral Nervous system, parasympathetic system, sympathetic system, Reflex • HW: due Wednesday read pages 432-439 in textbook. Answer questions 439 #’s 1-4 on loose leaf. Remember to write questions and answers!

  2. Function of the Nervous System • Process Information • Stores Information • Controls Voluntary movements • Controls Involuntary process and actions • Stimulus Vs Response

  3. Types of Neurons • Sensory Neurons • Interneurons • Motor Neurons

  4. Aim: How is the nervous system arranged and what is the function of the synapse? • Do Now: How does a neuron’s structure compliment its function? • Vocabulary: Neurons, impulses, synapse, neurotransmitters, sensory neurons, inter neurons, motor neurons, Peripheral Nervous system, parasympathetic system, sympathetic system, Reflex • HW: due tomorrow read pages 432-439 in textbook. Answer questions 439 #’s 1-4 on loose leaf. Remember to write questions and answers! • Journals due on Tuesday for those participating in the research project

  5. What is a Neuron? Sketch a picture in your notebooks Work together to label and define the parts of the neuron Cell Body

  6. The Synapse and Neurotransmitters…

  7. Synaptic Animation • http://www.bishopstopford.com/faculties/science/arthur/synapse.swf

  8. Parts of the Nervous System

  9. Aim: What are the parts to the nervous system? • Do Now: What is the function of a neurotransmitter? What would happen if a neurotransmitter stayed bound to a receptor site for a long period of time? • Hand in HW

  10. Review of HW pg 439 • List and Describe the role of the three kinds of neurons. • What two parts of the brain are responsible for controlling your balance and coordination? • The synapse plays an important role in the transmission of an impulse. What might happen if an impulse is unable to travel across a synapse for some reason? • List three feelings you might experience and describe what part of the autonomic nervous system will be most involved with each feeling.

  11. Discussion Questions… • Based on the information about the nervous system how do you think a drug like aspirin might affect nerve impulses? • How do you think it might affect the sympathetic and parasympathetic nervous systems?

  12. Aim: How do drugs affect the body? • Do Now: What is the difference between the sympathetic and parasympathetic systems. • HW: Pg 450 questions 1-5 due tomorrow. • Test next week on 12/12

  13. Activity • Define the difference between legal drugs and illegal drugs. • What are the different methods for administering a drug? • How do drugs affect the brain? • Describe the different types of drugs. • What is a side effect?
